- Continuous improvement mindset
Section 1: Core Technical Interview Questions
1. What are the key responsibilities of a Salesforce Technical Lead, and how do you prioritize them?
What They’re Looking For: Understanding of the multi-faceted role and ability to balance competing priorities.
How to Answer:
As a Salesforce Technical Lead, my responsibilities span technical, leadership, and strategic domains. I prioritize responsibilities based on a framework that considers impact, urgency, and alignment with business objectives.
My Priority Framework:
- Critical Issues First: System availability, data integrity problems, or security vulnerabilities take immediate precedence
- High-Impact Technical Decisions: Architecture choices that affect multiple teams or long-term scalability
- Team Development: Regular code reviews, mentoring sessions, and removing technical blockers
- Strategic Planning: Long-term technical roadmap and technical debt management
- Stakeholder Communication: Regular updates and alignment meetings
Example: In my previous role, when a critical data synchronization issue affected multiple departments, I immediately prioritized debugging and resolution while delegating routine code reviews to senior developers. This allowed me to fix the critical issue within hours while maintaining team productivity.
2. Can you explain the difference between Salesforce roles, profiles, and permission sets?
Technical Answer:
Understanding Salesforce’s security model is fundamental for a tech lead:
Roles:
- Define organizational hierarchy
- Control record-level access through role hierarchy
- Enable data visibility based on ownership
- Support the “Grant Access Using Hierarchies” feature
- Essential for OWD (Organization-Wide Defaults) implementation
Profiles:
- Every user must have exactly one profile
- Control object and field-level permissions (CRUD)
- Determine page layout assignments
- Set login hours and IP restrictions
- Define default record types
- More rigid and difficult to maintain at scale
Permission Sets:
- Extend permissions beyond the profile
- Provide flexible, additive permissions
- Enable role-based access without changing profiles
- Support better maintainability and scalability
- Can be grouped for easier management
Best Practice Architecture:
Profile (Minimal Permissions)
+ Permission Sets (Role-Specific Access)
+ Permission Set Groups (Department Access)
= User's Complete Access
Pro Tip: I recommend a “minimum profile, maximum permission sets” strategy for enterprise implementations, which provides greater flexibility and reduces profile proliferation.
3. How do you approach designing scalable and secure Salesforce architectures?
Comprehensive Strategy:
Scalability Considerations:
Data Volume Planning:
- Anticipate data growth over 3-5 years
- Plan for archiving strategies early
- Consider Big Objects for massive datasets
- Implement proper indexing strategies
- Use External Objects for external data access
Performance Optimization:
- Design selective SOQL queries
- Implement lazy loading in Lightning components
- Use platform caching strategically
- Minimize API calls in integrations
- Bulkify all Apex code
Integration Scalability:
- Use Platform Events for event-driven architecture
- Implement queueable Apex for async processing
- Design for idempotent API operations
- Plan for API limit management
- Consider MuleSoft for complex integration patterns
Security Architecture:
Defense in Depth:
- Start with restrictive OWDs
- Layer security with role hierarchy
- Add criteria-based sharing rules
- Implement field-level security
- Use Shield Platform Encryption for sensitive data
Integration Security:
- OAuth 2.0 for authentication
- Named Credentials for secure storage
- IP restrictions and session management
- API key rotation policies
- Regular security audits
Example Architecture Decision:
// Example: Implementing a scalable trigger framework
trigger AccountTrigger on Account (before insert, before update,
after insert, after update) {
// Delegate to handler for clean architecture
new AccountTriggerHandler().run();
}
public class AccountTriggerHandler extends TriggerHandler {
// Centralized trigger logic with bulkification
protected override void beforeInsert() {
AccountService. validateAccounts(Trigger.new);
AccountService. enrichAccountData(Trigger.new) ;
}
protected override void afterInsert() {
// Async processing for non-critical operations
AccountAsyncProcessor. processNewAccounts(Trigger. newMap.keySet());
}
} 4. What are the key differences between Lightning Web Components (LWC) and Aura components?
In-Depth Technical Comparison:
| Aspect | Lightning Web Components (LWC) | Aura Components |
|---|---|---|
| Framework | Built on modern web standards (ES6+) | Proprietary Salesforce framework |
| Performance | Faster, more lightweight | Heavier, more resource-intensive |
| Learning Curve | Easier for web developers | Steeper learning curve |
| Browser Compatibility | Leverages native browser capabilities | Requires Aura framework overhead |
| Component Communication | DOM events, pub-sub pattern | Aura events (component, application) |
| Data Binding | One-way by default | Two-way data binding |
| Testing | Jest testing framework | Jasmine, more complex setup |
| Future Support | Primary focus, future-proof | Maintenance mode |
| Interoperability | Can contain Aura components | Cannot contain LWC |
When to Use Each:
Choose LWC When:
- Starting new projects (always recommended)
- Performance is critical
- Team has modern JavaScript skills
- Building reusable components
- Need better testing capabilities
Consider Aura When:
- Maintaining existing Aura applications
- Need specific Aura-only features (rare)
- Heavy investment in existing Aura components
- Working with legacy integrations
Migration Strategy: For existing Aura applications, I recommend a gradual migration approach:
- Build new features in LWC
- Create LWC wrapper components for shared functionality
- Migrate high-traffic components first for maximum impact
- Maintain Aura for complex legacy components until fully understood
- Establish migration sprints in your technical roadmap
5. Explain the role of triggers in Salesforce. What are some best practices to follow when writing Apex triggers?
Trigger Fundamentals:
Apex triggers are powerful automation tools that execute custom logic before or after database operations (insert, update, delete, undelete). However, poorly written triggers are a leading cause of performance issues and technical debt.
Best Practices Framework:
1. One Trigger Per Object Pattern:
trigger AccountTrigger on Account (before insert, before update,
before delete, after insert,
after update, after delete,
after undelete) {
// Single entry point - delegate to handler
AccountTriggerHandler. handleTrigger();
}
Benefits:
- Predictable execution order
- Easier to maintain and debug
- Prevents trigger conflicts
- Cleaner architecture
2. Bulkification – Always:
// BAD - Not bulkified
trigger AccountTrigger on Account (after insert) {
for(Account acc : Trigger.new) {
// NEVER do DML in a loop
Contact con = new Contact(
LastName = acc.Name,
AccountId = acc.Id
);
insert con; // Governor limit violation!
}
}
// GOOD - Bulkified
trigger AccountTrigger on Account (after insert) {
List<Contact> contactsToInsert = new List<Contact>();
for(Account acc : Trigger.new) {
contactsToInsert.add(new Contact(
LastName = acc.Name,
AccountId = acc.Id
));
}
if(!contactsToInsert.isEmpty() ) {
insert contactsToInsert; // Single DML operation
}
}
3. Use Helper Classes:
trigger AccountTrigger on Account (before insert, after update) {
if(Trigger.isBefore && Trigger.isInsert) {
AccountTriggerHelper. setDefaultValues(Trigger.new);
}
if(Trigger.isAfter && Trigger.isUpdate) {
AccountTriggerHelper. updateRelatedRecords(
Trigger.newMap,
Trigger.oldMap
);
}
}
4. Implement Recursion Control:
public class TriggerHelper {
private static Set<String> processedTriggers = new Set<String>();
public static Boolean hasRun(String triggerName) {
return processedTriggers.contains( triggerName);
}
public static void markAsRun(String triggerName) {
processedTriggers.add( triggerName);
}
}
// Usage in trigger
if(!TriggerHelper.hasRun(' AccountUpdate')) {
TriggerHelper.markAsRun(' AccountUpdate');
// Execute trigger logic
}
5. Comprehensive Error Handling:
public class AccountTriggerHelper {
public static void processAccounts(List<Account> accounts) {
try {
// Business logic here
validateAccounts(accounts);
enrichData(accounts);
} catch(Exception e) {
// Log error
Logger.error('AccountTrigger Error', e);
// Add error to records if in before context
if(Trigger.isBefore) {
accounts[0].addError('An error occurred: ' + e.getMessage());
}
}
}
} Additional Best Practices:
- Avoid SOQL queries inside loops
- Use Trigger.newMap and Trigger.oldMap for efficient lookups
- Implement trigger frameworks (e.g., fflib Apex Common)
- Write comprehensive test classes with 100% coverage
- Document complex business logic
- Use platform events for async operations when possible
6. How do you handle governor limits in Salesforce, especially in large data processing scenarios?
Comprehensive Governor Limit Strategy:
Governor limits are Salesforce’s way of ensuring multi-tenant system stability. A skilled technical lead must design solutions that work within these constraints.
Understanding Key Limits:
| Operation | Synchronous Limit | Asynchronous Limit |
|---|---|---|
| SOQL Queries | 100 | 200 |
| SOQL Records | 50,000 | 50,000 |
| DML Statements | 150 | 150 |
| DML Rows | 10,000 | 10,000 |
| Callouts | 100 | 100 |
| CPU Time | 10,000ms | 60,000ms |
| Heap Size | 6 MB | 12 MB |
Strategies for Large Data Processing:
1. Batch Apex for Volume:
global class AccountCleanupBatch implements Database.Batchable<SObject> {
global Database.QueryLocator start(Database. BatchableContext bc) {
// Query runs once, not counted against limits
return Database.getQueryLocator(
'SELECT Id, Name FROM Account WHERE LastModifiedDate < LAST_N_DAYS:365'
);
}
global void execute(Database. BatchableContext bc, List<Account> scope) {
// Process up to 200 records per execution
// Fresh governor limits for each batch
List<Account> toUpdate = new List<Account>();
for(Account acc : scope) {
acc.Status__c = 'Archived';
toUpdate.add(acc);
}
update toUpdate;
}
global void finish(Database. BatchableContext bc) {
// Post-processing logic
System.debug('Batch job completed');
}
}
// Execute with optimal batch size
Database.executeBatch(new AccountCleanupBatch(), 200);
2. Queueable Apex for Chaining:
public class OpportunityProcessor implements Queueable {
private List<Id> opportunityIds;
public OpportunityProcessor(List<Id> oppIds) {
this.opportunityIds = oppIds;
}
public void execute(QueueableContext context) {
// Process opportunities
List<Opportunity> opps = [
SELECT Id, Amount FROM Opportunity
WHERE Id IN :opportunityIds
LIMIT 100
];
// Business logic here
processOpportunities(opps);
// Chain next job if more records exist
if(opportunityIds.size() > 100) {
List<Id> remainingIds = new List<Id>();
for(Integer i = 100; i < opportunityIds.size(); i++) {
remainingIds.add( opportunityIds[i]);
}
System.enqueueJob(new OpportunityProcessor( remainingIds));
}
}
}
3. SOQL For Loops for Memory Efficiency:
// Traditional approach - loads all records into memory
List<Account> accounts = [SELECT Id, Name FROM Account];
for(Account acc : accounts) {
// Process - could hit heap limit with large datasets
}
// SOQL For Loop - processes in chunks of 200
for(List<Account> accountBatch : [SELECT Id, Name FROM Account]) {
// Processes 200 records at a time
// More memory efficient
for(Account acc : accountBatch) {
// Process each account
}
}
4. Platform Events for Decoupling:
// Publish event instead of immediate processing
Order_Placed__e orderEvent = new Order_Placed__e(
Order_Id__c = orderId,
Customer_Id__c = customerId
);
EventBus.publish(orderEvent);
// Separate trigger processes asynchronously
trigger OrderPlacedEventTrigger on Order_Placed__e (after insert) {
List<Order__c> ordersToUpdate = new List<Order__c>();
for(Order_Placed__e event : Trigger.new) {
// Process event
// Fresh set of governor limits
}
}
5. Query Optimization:
// BAD - Queries in loop
for(Account acc : accounts) {
List<Contact> contacts = [
SELECT Id FROM Contact WHERE AccountId = :acc.Id
];
// 100 queries if 100 accounts
}
// GOOD - Single query with relationship
Map<Id, Account> accountMap = new Map<Id, Account>([
SELECT Id,
(SELECT Id FROM Contacts)
FROM Account
WHERE Id IN :accountIds
]);
for(Account acc : accountMap.values()) {
List<Contact> contacts = acc.Contacts;
// Process contacts
}
Monitoring and Prevention:
- Use Limits class to check limit consumption
- Implement logging for limit warnings
- Use Developer Console’s Limits tab
- Set up Event Monitoring for production issues
- Regular code reviews focusing on limit optimization
Section 2: Architecture and Design Questions
7. Describe the Salesforce sharing model. How do you implement it in a complex organization?
Comprehensive Sharing Model Strategy:
The Salesforce sharing model provides enterprise-grade, flexible security. Understanding and implementing it correctly is crucial for technical leads.
Core Components:
1. Organization-Wide Defaults (OWD):
Public Read/Write > Public Read Only > Private
Best Practice: Start with the most restrictive settings, then open access incrementally.
2. Role Hierarchy:
- Automatic access to records owned by subordinates
- “Grant Access Using Hierarchies” checkbox controls this behavior
- Essential for sales and management reporting structures
3. Sharing Rules:
- Owner-based: Share records based on owner characteristics
- Criteria-based: Share based on record field values
- Additive only (cannot restrict access)
- Recalculated when criteria changes
4. Manual Sharing:
- Ad-hoc record access
- Granted by record owners or above in hierarchy
- Use sparingly for exceptional cases
5. Teams (for Accounts and Opportunities):
- Collaborative access for cross-functional teams
- Independent of role hierarchy
- Flexible team member roles
Complex Organization Implementation:
Scenario: Global manufacturing company with regional sales teams, product specialists, and support teams.
Architecture:
OWD Settings:
- Account: Private
- Opportunity: Private
- Case: Public Read Only
- Lead: Public Read/Write
Role Hierarchy:
CEO
├── VP Sales Americas
│ ├── Regional Manager East
│ │ └── Account Executives
│ └── Regional Manager West
│ └── Account Executives
├── VP Sales EMEA
└── VP Sales APAC
Sharing Rules:
1. Share accounts with Regional Managers based on Account.Region__c
2. Share opportunities with Product Specialists when Product_Line__c matches
3. Share cases with Support Queue when Status != 'Closed'
Public Groups:
- Product_Specialists_Group
- Support_Team_Global
- Finance_Team
Implementation Considerations:
Performance Impact:
- Sharing rule recalculations can be expensive
- Defer sharing rule recalculation during large data loads
- Monitor sharing rule count (< 300 recommended)
Maintenance Strategy:
- Document sharing model decisions
- Regular audits of sharing rules
- Remove obsolete rules promptly
- Use public groups for flexibility
Testing Approach:
@IsTest
private class AccountSharingTest {
@IsTest
static void testRegionalSharing() {
// Create users in different regions
User eastManager = TestDataFactory.createUser(' East Manager');
User westManager = TestDataFactory.createUser(' West Manager');
// Create accounts
Account eastAccount;
System.runAs(eastManager) {
eastAccount = new Account(
Name = 'East Account',
Region__c = 'East'
);
insert eastAccount;
}
// Verify sharing
System.runAs(westManager) {
List<Account> visibleAccounts = [
SELECT Id FROM Account WHERE Id = :eastAccount.Id
];
System.assertEquals(0, visibleAccounts.size(),
'West manager should not see East accounts');
}
}
} 8. What are the key considerations when integrating Salesforce with other systems?
Comprehensive Integration Strategy:
1. Integration Pattern Selection:
| Pattern | Use Case | Best For |
|---|---|---|
| Request-Reply | Synchronous data exchange | Real-time validation, single record operations |
| Fire-and-Forget | One-way asynchronous | Non-critical notifications, logging |
| Batch Data Sync | Scheduled bulk transfers | Nightly data synchronization |
| Remote Call-In | External systems triggering Salesforce | Web-to-Lead, API integrations |
| UI Update | Real-time UI refresh | Live data displays, dashboards |
2. Authentication Methods:
OAuth 2.0 Flows:
// Example: Web Server Flow implementation
public class OAuthController {
public PageReference authorize() {
String authUrl = 'https://login.salesforce.com/ services/oauth2/authorize';
authUrl += '?response_type=code';
authUrl += '&client_id=' + CLIENT_ID;
authUrl += '&redirect_uri=' + EncodingUtil.urlEncode( REDIRECT_URI, 'UTF-8');
authUrl += '&state=' + STATE_TOKEN;
PageReference ref = new PageReference(authUrl);
return ref;
}
public void handleCallback() {
String code = ApexPages.currentPage(). getParameters().get('code');
// Exchange code for access token
HttpRequest req = new HttpRequest();
req.setEndpoint('https:// login.salesforce.com/services/ oauth2/token');
req.setMethod('POST');
req.setBody('grant_type= authorization_code' +
'&code=' + code +
'&client_id=' + CLIENT_ID +
'&client_secret=' + CLIENT_SECRET +
'&redirect_uri=' + REDIRECT_URI);
Http http = new Http();
HttpResponse res = http.send(req);
// Parse and store access token
}
}
3. Error Handling and Retry Logic:
public class ResilientIntegrationService {
private static final Integer MAX_RETRIES = 3;
private static final Integer RETRY_DELAY = 1000; // milliseconds
public static HttpResponse callExternalAPI(String endpoint, String method) {
Integer attempts = 0;
HttpResponse response;
while(attempts < MAX_RETRIES) {
try {
HttpRequest req = new HttpRequest();
req.setEndpoint(endpoint);
req.setMethod(method);
req.setTimeout(30000);
Http http = new Http();
response = http.send(req);
if(response.getStatusCode() == 200) {
return response; // Success
} else if(response.getStatusCode() >= 500) {
// Server error - retry
attempts++;
if(attempts < MAX_RETRIES) {
// Exponential backoff
Long delay = RETRY_DELAY * Math.pow(2, attempts);
Thread.sleep(delay);
}
} else {
// Client error - don't retry
throw new IntegrationException(
'API returned error: ' + response.getStatusCode()
);
}
} catch(Exception e) {
attempts++;
if(attempts >= MAX_RETRIES) {
// Log and throw
Logger.error('Integration failed after retries', e);
throw e;
}
}
}
throw new IntegrationException('Max retries exceeded');
}
}
4. Data Transformation and Mapping:
public class DataTransformationService {
// Map external system data to Salesforce
public static Account transformToAccount( ExternalAccountDTO dto) {
Account acc = new Account();
acc.Name = dto.companyName;
acc.Phone = formatPhoneNumber(dto. phoneNumber);
acc.BillingStreet = dto.address.street;
acc.BillingCity = dto.address.city;
acc.BillingState = mapStateCode(dto.address. stateCode);
acc.External_Id__c = dto.accountId;
return acc;
}
private static String formatPhoneNumber(String phone) {
// Remove all non-numeric characters
String cleaned = phone.replaceAll('[^0-9]', '');
// Format as (XXX) XXX-XXXX
if(cleaned.length() == 10) {
return '(' + cleaned.substring(0,3) + ') ' +
cleaned.substring(3,6) + '-' +
cleaned.substring(6);
}
return cleaned;
}
}
5. Performance Optimization:
- Use bulk APIs for large data volumes
- Implement caching for frequently accessed data
- Use compression for payload reduction
- Leverage platform events for async processing
- Monitor API usage and implement rate limiting
6. Security Considerations:
- Store credentials in Named Credentials
- Use custom settings for configuration
- Implement IP whitelisting
- Encrypt sensitive data in transit and at rest
- Regular security audits of integration points
- Implement token rotation policies

4. Managing Performance:
Constructive Feedback Framework:
Situation: During the recent sprint, I noticed...
Behavior: The code review feedback wasn't addressed before merging...
Impact: This resulted in production issues that affected users...
Discussion: Let's talk about what happened and how we can prevent this...
Action Plan: Moving forward, let's establish a checklist before merging...
5. Conflict Resolution:
Example Scenario: Two developers disagree on implementation approach.
Resolution Process:
- Listen to Both Perspectives: Hold a meeting, let each explain their approach
- Focus on Objectives: Redirect to business goals and technical requirements
- Evaluate Trade-offs: Create pros/cons list for each approach
- Data-Driven Decision: Use metrics (performance, maintainability, time-to-market)
- Document Decision: Record rationale for future reference
- Follow-up: Check implementation and outcomes
10. How do you communicate complex Salesforce concepts to non-technical stakeholders?
Effective Communication Strategies:
1. Use Analogies and Metaphors:
Example – Explaining Triggers:
- “Think of a trigger like a security system. When someone opens a door (insert record), it automatically turns on the lights (updates related records) and sends a notification (creates tasks).”
Example – Explaining Governor Limits:
- “Imagine Salesforce as a shared highway. Governor limits are like speed limits and lane rules – they ensure everyone can use the highway safely without one person causing traffic for everyone else.”
Example – Explaining Integration:
- “Integration is like a translator between two people who speak different languages. Our system speaks ‘Salesforce,’ their system speaks ‘SAP,’ and the integration translates between them so they can understand each other.”
2. Visual Communication:
Use Flowcharts:
[User Submits Form]
↓
[Validation Rules Check]
↓
[Trigger Fires] → [Create Contact] → [Send Welcome Email]
↓
[Workflow Updates Owner]
↓
[Record Saved Successfully]
Create Diagrams:
- System architecture diagrams
- Data flow diagrams
- Before/After process comparisons
- ROI and benefits visualization
3. Focus on Business Value:
Instead of: “We’ll implement a batch apex job with queueable chaining…”
Say: “We’ll automate the monthly report generation process, saving your team 20 hours per month and ensuring reports are always accurate and on-time.”
Instead of: “The sharing model needs OWD restructuring…”
Say: “We’ll ensure sales reps in different regions can only see their own accounts, protecting competitive information while enabling management visibility.”
4. Progressive Disclosure:
Start with high-level concepts, then drill deeper only if they want more detail:
Level 1: “We’re improving system performance.”
Level 2: “We’re optimizing how the system processes large amounts of data.”
Level 3: “We’re implementing batch processing to handle 100,000 records more efficiently.”
Level 4: “We’re using Batch Apex with optimized chunk sizes to stay within governor limits while processing data asynchronously.”
5. Documentation for Stakeholders:
Create different documentation levels:
- Executive Summary: One-page overview with business impact
- Manager Brief: 2-3 pages with key decisions and timelines
- Detailed Technical Spec: Complete documentation for technical review
Section 4: Scenario-Based Interview Questions
Since most Technical Leads grow from senior developer roles, revisiting structured preparation like How to Prepare for a Salesforce Developer Interview (Step-by-Step Guide) helps reinforce core concepts tested at scale.

3. Test Coverage Standards:
Minimum Requirements:
- 85% overall coverage (Salesforce requirement)
- 100% coverage on critical business logic
- All triggers must have test coverage
- All public methods must have tests
Quality Test Example:
@IsTest
private class AccountServiceTest {
@TestSetup
static void setupTestData() {
// Create reusable test data
TestDataFactory. createAccounts(200); // Bulk testing
}
@IsTest
static void testAccountCreation_Success() {
// Positive test case
Account acc = new Account(Name = 'Test Account');
Test.startTest();
insert acc;
Test.stopTest();
// Verify results
Account inserted = [SELECT Id, Name FROM Account WHERE Id = :acc.Id];
System.assertEquals('Test Account', inserted.Name);
System.assertNotEquals(null, inserted.Id);
}
@IsTest
static void testAccountCreation_ BulkOperation() {
// Bulk test case
List<Account> accounts = new List<Account>();
for(Integer i = 0; i < 200; i++) {
accounts.add(new Account(Name = 'Bulk Test ' + i));
}
Test.startTest();
insert accounts;
Test.stopTest();
// Verify all inserted
Integer count = [SELECT COUNT() FROM Account WHERE Name LIKE 'Bulk Test%'];
System.assertEquals(200, count);
}
@IsTest
static void testAccountCreation_ NegativeCase() {
// Negative test case
Account acc = new Account(); // Missing required Name field
Test.startTest();
try {
insert acc;
System.assert(false, 'Should have thrown exception');
} catch(DmlException e) {
// Expected exception
System.assert(e.getMessage(). contains('REQUIRED_FIELD_ MISSING'));
}
Test.stopTest();
}
@IsTest
static void testExternalCallout_Mocked() {
// Mock external callout
Test.setMock(HttpCalloutMock. class, new MockHttpResponseGenerator());
Test.startTest();
HttpResponse res = ExternalService.callAPI();
Test.stopTest();
System.assertEquals(200, res.getStatusCode());
}
}
4. Documentation Standards:
Code Documentation:
/**
* Service class for managing Account operations
*
* @author John Doe
* @date 2026-01-15
* @version 1.0
*
* @group Account Management
* @description Handles complex account operations including territory assignment,
* revenue calculations, and integration with external systems
*/
public with sharing class AccountService {
/**
* Creates accounts with proper validation and territory assignment
*
* @param accounts List of Account records to create
* @return List<Database.SaveResult> Results of the insert operation
*
* @throws AccountValidationException if validation fails
*
* @example
* List<Account> accts = new List<Account>{
* new Account(Name = 'Test Corp', Industry = 'Technology')
* };
* List<Database.SaveResult> results = AccountService.createAccounts( accts);
*/
public static List<Database.SaveResult> createAccounts(List<Account> accounts) {
// Validate accounts
validateAccounts(accounts);
// Assign territories
assignTerritories(accounts);
// Insert with partial success
return Database.insert(accounts, false);
