Adaptive difficulty, spaced revision, mastery tracking and role-specific scoring.

How it works

From cold start to first roundin under 60 seconds.

Four steps. No setup hell, no fake quizzes — just a real round, a real scorecard, and the next drill queued up.

  1. 01
    Sign up

    Drop a resume or pick a role.

    60-second onboarding. Choose target role, language, and stack — Dosti calibrates difficulty before round one.

  2. 02
    Practice

    Step into a live voice round.

    Saarthi or Vega listens, interrupts, and pushes back. Code on the same screen — exactly like the real round.

  3. 03
    Score

    See where you slipped, line by line.

    Transcript, code diff, scorecard, and one-line tips per moment — clarity, edge cases, depth, communication.

  4. 04
    Loop

    Drill the gap. Repeat tomorrow.

    Adaptive assessments + a study plan target your weakest topic next. Mastery tracked across all 12 domains.

First mock round is free — no card, no recruiter feed, no employer ever sees your scores.

    Walk me through how you'd design a URL shortener for 100M URLs/day.
  • Sure — let me start with the read/write ratio and then key generation strategy…

    Good. Push back: what if a single base62 collision costs you a duplicate?
