Level 1

Intern / Fresher

Foundational concepts and basic definitions. Questions focus on what you've learned, not production experience.

"What is REST?" "Explain arrays vs linked lists."

Level 2

Junior

Practical applications and hands-on scenarios. Expect questions about implementation and debugging.

"How would you implement auth in a web app?"

Level 3

Mid-Level

Architecture decisions, trade-off analysis, and system design. Deeper technical discussions that test your ability to reason about complex systems, evaluate alternatives, and communicate design choices clearly.

"Design a URL shortener. How would you handle database scaling for a growing application?"

Level 4

Senior

Advanced system design, scalability, technical strategy, and leadership. Complex trade-off discussions.

"Design a distributed cache for 1B users."

Adaptive

Auto-Adjusting

The interviewer tracks your performance in real-time. Consecutive strong answers push difficulty up. Struggles trigger simpler questions and guided hints.

Difficulty shifts mid-interview based on your responses.

Gets harder when you're strong. Easier when you struggle.

The interviewer tracks your performance and adjusts in real-time — so you're always practicing at the right level.
