What makes the Platform Developer hard
Developers from other stacks often walk into Platform Developer expecting a coding exam and find a platform exam instead. Apex syntax is the easy part.
What decides it: governor limits and how to bulkify around them, the order of execution when a record saves, trigger patterns that avoid recursion, and knowing when the platform wants declarative automation instead of code at all. Add SOQL versus SOSL, the 75% test coverage rule and what actually counts toward it, and Lightning Web Component fundamentals, and the exam becomes a test of how Salesforce thinks, not how well you write loops.
60 scored questions plus 5 unscored in 105 minutes, with a 68% pass mark. This pack covers the exact limit, trigger and order-of-execution scenarios that fill the paper.
