The journey

One mentor. Your whole engineering journey.

Seven stops, one Lala. Scroll through, and tap anything that moves.

  1. 01 · Learn

    Find your gap, then learn it

    Lala checks what you know and teaches the missing piece.

    Learn with Lala

    Sample: Lala asks a check question about caching, you answer, and she names the gap to learn next.

    Sample
    Quick check: after a write, your API still returns the old value. What happened?
    1 question · topic: caching

  2. 02 · Practice

    Solve DSA with hints, not answers

    Stuck? Get a nudge toward the bug, never the solution.

    Practice DSA

    Sample: a code snippet where a hint highlights the line with an off-by-one bug.

    Sample
    1. function findMax(nums) {
    2. let max = 0;
    3. for (let i = 0; i < nums.length; i++) {
    4. if (nums[i] > max) max = nums[i];
    5. }
    6. return max;
    7. }

    Stuck? Lala points at the problem. You write the fix.

  3. 03 · Prepare

    Draw the system, get it evaluated

    Sketch the architecture. Lala reviews it against a rubric.

    Practice system design

    Sample: a client, load balancer, API, cache and database connect, and the review flags missing cache invalidation.

    Sample

    Diagram: a client calls a load balancer, which routes to the API. The API reads from a cache and writes to a database.

    Five boxes, four arrows. Ask for a review against the rubric.

  4. 04 · Evaluate

    Mock interview, by voice or chat

    Speak or type. English, Hindi, Hinglish and nine more languages.

    Start a mock interview

    Sample: a voice round where Lala greets you and asks the first question.

    Sample

    Pick a language, then tap the mic. Lala asks the first question.

    Feedback that tells you what's next

    What went well, what to fix, why, and the next step.

    See how reviews work

    Sample review: a score of 78 out of 100 with what went well, what to improve, why, how, and the next step.

    Sample

    78/100

    Behavioral · a team conflict

    • Went well

      Clear STAR structure around one real project

    • Improve

      Your own role got lost in “we did”

    • Why it matters

      Interviewers score your decisions, not the team's

    • How

      Say “I” for each call you made and name one trade-off

    • Next

      Practise: a failure story in two minutes

  6. 06 · Get hired

    A resume that passes the first screen

    Tailor it to the job and check the ATS score.
