AI's Superpower: Asking Questions for Tech Interviews
You just spent an hour debugging a gnarly memory leak in a microservice. Your brain's fried. Now you need to prep for a Google Staff Engineer interview tomorrow morning, and you still haven't touched the system design problem. This is where AI's real superpower kicks in for tech interviews: it excels at asking incisive questions. Forget about asking ChatGPT to solve the problem for you. That's cheating and useless for learning. Instead, make it your personal, tireless interviewer, probing your assumptions, pointing out blind spots, and pushing you to articulate your ideas under pressure.
Why Your Brain (and Most Mock Interviewers) Can't Compete
Most humans make terrible mock interviewers. They get bored. They have their own biases. They might even try to "help" you too much. A good senior engineer can give a decent mock, sure, but they're expensive and scarce. Your brain? It knows what you think you know, so it struggles to ask the truly probing questions that expose gaps. It’s like trying to tickle yourself—you anticipate the move. AI, on the other hand, operates purely on your input and its training data. It doesn’t care if you get the answer "right"; it cares about exploring the problem space effectively.
Think about a system design interview. You start sketching out components: a load balancer, some web servers, a database. A human might nod along. An AI, if prompted correctly, could immediately hit you with: "You've proposed an NGINX load balancer. How would you handle sticky sessions, and what are the trade-offs of that approach versus using a distributed cache for session state?" Or, "Your database choice is PostgreSQL. Why not Cassandra for this specific read-heavy, eventually consistent use case? What are the implications for data consistency and scalability?" These aren't trick questions; they’re fundamental considerations. An AI will ask them relentlessly, forcing you to justify every decision.
Prompting AI for Maximum Interview Pain (The Good Kind)
The trick to leveraging AI isn't just "ask me interview questions." That's too broad. You need to be specific. Tell it its role, the scenario, and what kind of feedback you want.
Here are a few starting prompts I use:
- "You are an interviewer from Google's Staff+ team. I'm interviewing for a Senior Staff Software Engineer role. Ask me system design questions related
