It’s a mix of behavioral, managerial, technical, and domain-related topics - not DSA or system design.

With 10 years of experience in big tech and countless interviews, I’ve compiled this first-hand guide to help you understand the types of questions you’ll face in major interview rounds. This is about software development processes, decision-making, and real-world problem-solving—the stuff that truly tests your engineering competency beyond just coding.

After reading this guide, you'll have a clear idea of the types of questions you can expect in major interview rounds as a senior software engineer or tech lead.

For each question, I’ll break down:

This isn’t just a list of questions—it’s a practical, no-nonsense breakdown to help you think like an interviewer and answer like a pro.
