Hire Salesforce developers by skill

Which screening questions work for Salesforce roles?

Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the Salesforce library.

1. Q1 How do you make a trigger safe for 200 records at once?
2. Q2 When would you build a Flow instead of writing Apex?
3. Q3 Tell us about a deployment between sandboxes that went wrong and what you changed.

What does the Salesforce coding task look like?

Bulk-safe opportunity trigger. Write a trigger handler that updates account totals when opportunities close, safe for bulk updates. Time limit 60 minutes.

1. Collect affected account ids without queries in loops
2. Aggregate totals in one query
3. Update accounts in one DML call
4. Write tests for 1 and 200 records

public with sharing class OpportunityTotals {
    public static void recalc(Set<Id> accountIds) {
        Map<Id, Decimal> totals = new Map<Id, Decimal>();
        for (AggregateResult r : [SELECT AccountId a, SUM(Amount) s FROM Opportunity WHERE IsWon = true AND AccountId IN :accountIds GROUP BY AccountId])
            totals.put((Id) r.get('a'), (Decimal) r.get('s'));
    }
}

How much does a Salesforce developer cost?

Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior Salesforce developers. Treat them as a starting point and check current surveys for your market.

Salesforce developers with integration and architecture experience are in steady demand, and senior pay often sits near the top of the range.
