Interview Format

The process is hands-on and practical. Interviewers care more about how you think and approach a problem than whether you arrive at the perfect answer — so walk them through your reasoning as you go.

Topics Covered

Core Java, data structures, design patterns, OOP, databases, cloud systems, system design, scalability, and resilience.

What Interviewers Are Looking For

Depth over breadth. They want to see that you genuinely understand the technologies you've worked with — not just how to use them, but why: the trade-offs involved, the alternatives you considered, and when one tool makes more sense than another.
