Practice the interview, not just the problem.
Start with free Practice Mode for DSA, then switch into AI Interview Mode when you want the interviewer to speak, challenge your thinking, watch your code, and score how you perform under pressure. Tia is ready when you want the real interview feel.
Free DSA practice with saved progress. One 5-minute audio preview included.

What Changes Here
LeetCode trains answers. Interviews test signal.
The hard part of real interviews is not just the solution. It is explaining the plan, surviving pushback, coding clearly, and still sounding composed when the clock is moving.
Why silent practice falls short
You never have to explain tradeoffs while you think.
No one challenges a slow or fuzzy approach in real time.
Testing often becomes optional instead of part of the evaluation.
You do not feel the pressure of voice + code + time all at once.
Communication is part of the test
Most prep only checks whether you can solve the problem. Real interviews also check how clearly you think out loud.
Weak approaches should get challenged
A real interviewer pushes back when your plan is too slow, too vague, or missing edge cases. Silent practice never does.
You need a realistic loop
The pressure comes from juggling voice, code, time, and testing together. That combined signal is what changes real outcomes.
Feedback should tell you what to fix next
Every round ends with a scorecard that pinpoints whether you missed clarity, rigor, speed, testing, or clean execution.
How It Works
A full interview arc, not a chatbot demo.
Each round moves through the same moments that matter in a real technical screen: understanding the problem, choosing the approach, coding clearly, validating edge cases, and defending complexity.
Adaptive interviewer behavior
If you stall, the interviewer can nudge. If your plan is weak, it pushes back. If your answer is strong, it raises the bar.
Built for repetition
Start on demand, finish with a concrete report, then run another round without scheduling anyone or waiting for feedback.
00:00 - 01:00
Quick intro and bar setting
Phase 1 · Introduction
The interviewer opens warmly, calibrates your background, and establishes that this is a real screen, not a practice sandbox with infinite hints.
01:00 - 02:00
Problem statement gets delivered live
Phase 2 · Problem
You hear the prompt, examples, and constraints the way you would in a live round, with enough context to start reasoning but not enough to skip thinking.
02:00 - 05:00
Clarify assumptions before you commit
Phase 3 · Clarification
Strong candidates use this window to de-risk ambiguity, confirm edge conditions, and show they know how to frame the problem before they touch the keyboard.
05:00 - 12:00
Explain the approach and defend it
Phase 4 · Approach
You walk through the plan, tradeoffs, and data structures. If the path is weak, the interviewer pushes back instead of letting you code into a dead end.
12:00 - 32:00
Code while the interviewer listens
Phase 5 · Coding
This is the long execution stretch: narrate key decisions, keep momentum, and recover cleanly if you hit a bug or need to change direction mid-solution.
32:00 - 37:00
Trace examples and hunt edge cases
Phase 6 · Testing
You prove the solution against concrete cases, talk through tricky inputs, and show whether you can debug systematically instead of hoping the code is right.
37:00 - 40:00
Defend time and space complexity
Phase 7 · Complexity
The interviewer pressures the analysis, checks whether the tradeoffs match the actual implementation, and looks for sloppy reasoning around scale.
40:00 - 43:00
Handle the harder variant if time allows
Phase 8 · Follow-up
Stronger rounds get stretched with a tighter constraint, a scaling twist, or a variant that forces you to generalize the original solution without panicking.
43:00 - 45:00
Close like a real technical screen
Phase 9 · Wrap-up
The round lands with a concise wrap-up instead of a vague ending, leaving enough signal across communication, execution, testing, and judgment to score credibly.
