Upanotch

Interview practice

Learn the move.
Then nail the round.

Upanotch is a quiet practice room for the topics that show up in interviews: system design, cloud, Linux, Docker, Kubernetes, Git and CI, databases, networking, application security, and the tricky questions meant to slow you down. Miss one, and you get the why plus a reading list.

How it works

A set, not a course.

No video player. No 40-page module. One question at a time, then a reading list only when you need it.

  1. 01

    Pick a topic

    Pick the track you are weakest in. Each set is a short drill, not a course.

  2. 02

    Answer under points

    Easy is 1, medium is 3, hard is 5. The score is a signal, not a leaderboard.

  3. 03

    Read the miss

    Every check comes with the why. A miss adds public docs you can open next.

Topics

Start a drill.

Each set is original. We do not copy paid interview banks. Links go to AWS, Azure, Docker, PostgreSQL, MDN, and other public sources. Start 10 if 50 is too long.
