Practice the interview, not just the problem.
Solve DSA problems free. When you are ready, run a 45-minute round with an AI interviewer that talks to you, reads your code as you type, and pushes back when your approach is weak.
The interviewer on one side. Your code on the other.
“Talk me through the brute force first, then tell me how you would get it to O(n). I care about how you reason, not just the final answer.”

LeetCode trains answers. Interviews test signal.
Plenty of people who fail a coding round could have solved the problem at home. They went quiet, skipped the clarifying questions, coded into a dead end, or never tested. Those habits only show up when someone is listening.
You have to think out loud
Interviewers grade how you explain the plan as well as the code. Practicing in silence skips half the test.
Weak approaches get challenged
Propose a nested loop and the interviewer asks if you can do better. Skip an edge case and it asks what happens on empty input.
The clock is real
A timer, a running editor and a voice waiting on your answer. That combination is what makes people freeze, so rehearse it.
Feedback you can act on
Every round ends with a scorecard: a score per dimension, written notes on what cost you points, and the transcript to check them against.
45 minutes, nine phases, from intro to wrap-up.
Quick intro and bar setting
Tone, confidence, and clarity get judged immediately.
The interviewer asks about your background and sets the tone: this is a real screen, and hints are limited.
Scored on five dimensions, with notes on each.
An overall score out of 100, a hire recommendation, written feedback per dimension and the full transcript. Behavioral and Engineering Manager rounds add a competency report graded against the value lens you picked.
Interview packs, not a subscription.
DSA practice is free. Pay once for full 45-minute AI interviews and use each credit on a coding, Technical Q&A, Engineering Manager or Behavioral round.

Before your first round.
How does the AI mock interview work?+−
You talk to an AI interviewer by voice while you code in a shared editor. A 45-minute coding round follows the shape of a real technical screen: intro, problem, clarifying questions, approach, coding, testing, complexity analysis, a follow-up and wrap-up. The interviewer sees your code as you write it and pushes back on a weak approach instead of approving whatever you say.
Which interview rounds can I practice?+−
DSA coding interviews, Technical Q&A, Engineering Manager and Behavioral rounds. Behavioral and Engineering Manager rounds are graded against a value lens you pick, such as Amazon Leadership Principles or Googleyness. System Design and Machine Coding are not available yet.
Which programming languages can I use?+−
Python and JavaScript run end to end, with test results shown in the editor. Java and C++ appear in the language picker, but running code in them is not supported yet. Use Python or JavaScript if you want to execute tests during the round.
How long is a session?+−
A full AI interview is 45 minutes. Practice Mode has no timer. Each new account gets one free 5-minute AI interview on an easy DSA problem, so you can try the voice format before buying a pack.
Do I need a subscription?+−
No. DSA Practice Mode is free and needs no card. AI interviews are sold as one-time packs of 1, 3 or 6 interviews, priced in your local currency, with no recurring billing.
Can I use it on my phone?+−
You can sign up and browse on a phone, but the interview room needs a laptop or desktop with a microphone. It shows the interviewer, the problem, your code and the tests side by side.
What do I get after the round?+−
An overall score out of 100, a hire recommendation from Strong Hire to No Hire, written feedback per dimension and the full transcript. Coding rounds are scored on problem solving, code quality, communication, technical knowledge and testing. Behavioral and Engineering Manager rounds add a competency report with evidence, gaps and STAR coverage for each competency.
