Mock Interview

A random DSA problem. A countdown timer. Hints and solution stay HIDDEN unless you reveal them — just like a real interview. Submit when the timer hits zero (or anytime you want out).

Difficulty

14 problems

Duration (minutes)

How to use this: talk through your approach OUT LOUD as if explaining to an interviewer. Pretend you can't look anything up. The hints are there as a safety net, but using them counts as "needed help."

Tips for getting the most out of this

Repeat the problem back in your own words before writing code.
State your approach AND complexity before coding it.
Walk through a small input by hand to verify your logic.
If stuck for 5 minutes, reveal one hint — but no more.
Run the tests at least twice: once to find bugs, once to verify your fix.
