How to actually answer the governor limits question in a Salesforce interview

Hey ,

The governor limits question comes up in almost every Salesforce developer interview. And most candidates answer it the same way.

They give a definition. Something about multi-tenant architecture and resource sharing. It's not wrong, but it's also not what the interviewer is looking for. They already know what governor limits are. What they're trying to figure out is whether you do too, in the way that only comes from building real things in real orgs.

Here's what a strong answer actually covers.

Why limits exist, not just what they are. Lead with the architecture. Salesforce runs on shared infrastructure. Every org is on the same platform. One piece of code running out of control affects everyone else. Saying that tells the interviewer you understand the environment you're building in.

The limits that actually matter in production. You don't need to memorize everything. But you should know the ones that come up most: 100 synchronous SOQL queries, 150 DML statements, 6MB heap size, 10,000ms CPU time. And for Batch Apex specifically, limits apply per batch chunk, not just per transaction. Most candidates don't know that one.

How you avoid them by habit. This is what separates a junior answer from a senior one. Bulkification, aggregate queries, moving work to async. And knowing which async option to reach for: future methods for simple offloads, Queueable for chaining jobs or passing complex data, Batch for processing large volumes across chunks.

A real story. Think about a time you hit a limit or caught one in a code review. Walk through what was happening and what you changed. It doesn't need to be dramatic. Even catching SOQL in a loop and refactoring it to use a map pattern is a solid story. It shows you've actually been there.

The bigger picture close. End your answer by connecting limits to code quality. Something like: "For me limits aren't just something to avoid. They're a signal. When I'm close to one it usually means the code needs to be rethought." That's a senior developer answer and interviewers remember it.
