Mock interviews that teach.

Tell Whyloop the job you want and share your CV. Your interviewer asks what that role is really hired for, keeps asking why until it finds the gaps, then teaches you what you missed.

How a session works

Most mock interviews stop at the score. Whyloop keeps going until you actually know it.

  1. 1

    Tell it the job

    Enter the role, your level and your CV. Paste the job ad if you have one.

  2. 2

    Get interviewed

    Real questions for that role, many tied to projects on your CV.

  3. 3

    It asks why

    Shallow answers get up to two follow-ups, like a sharp interviewer would ask.

  4. 4

    See what you missed

    A score on four dimensions, and the points a strong answer would cover.

  5. 5

    Learn it, then get retested

    Missed concepts become short audio lessons and come back in a later interview.

    Includes audio lessons

It asks why.

A shallow answer gets a follow-up, the way a sharp interviewer digs deeper. Up to two, and only when there is something to find. Strong answers move straight on.

We deferred some initialisation and lazy loaded a few heavy screens.

Why were those the bottleneck? How did you know, before you changed anything?
