Interview Formats
One interviewer. Three rounds.
Pick the format that matches your next interview. Same AI, different muscle. You can switch formats any time - credits are shared.
01
Theory
CS fundamentals, algorithms, language deep-dives.
- Data structures and complexity questions.
- Language internals: memory, concurrency, runtime.
- Algorithm trade-offs and when to pick what.
Example question
Explain how a HashMap resizes - and what happens to in-flight reads during rehash.
02
Practical
System design, architecture, real trade-offs with follow-ups.
- Design under constraints: scale, latency, cost.
- Trade-off questions with concrete numbers.
- Production war stories and debugging drills.
Example question
Design a URL shortener for 10 billion redirects per month - where does the bottleneck move first?
03
Behavioral
STAR stories, leadership, conflict and ambiguity.
- Situation-Task-Action-Result framing drills.
- Leadership and influence without authority.
- Conflict, failure, and recovery stories.
Example question
