AI Go (Golang) interviewer

Goroutines, channels and interfaces — a live Go interview that follows up on concurrency the way real interviewers do.

Free 10-minute interview with a full report. Paid plans run full-length sessions.

Go interview questions you might get

A sample of the starting questions. The live interview follows up on your answer, so no two sessions go the same way.

  1. What happens when you append to a slice that shares an underlying array?

    What it tests: Slice semantics.

  2. Build a worker pool that processes jobs with a concurrency limit.

    What it tests: Concurrency patterns.

  3. How do you detect and fix a goroutine leak?

    What it tests: Concurrency debugging.

  4. When should a function return an error versus panic?

    What it tests: Error philosophy.

  5. How do you cancel work across goroutines?

    What it tests: context usage.

How a session works

About 20–30 minutes from setup to report. End any time and you still get feedback on what was covered.

  1. Set your target

    Pick a role, level and stack. Add a job description or your resume if you want questions about your real projects.

  2. Answer live

    Speak or type. The interviewer follows up on thin answers, raises the difficulty when you're doing well and switches to code when it fits.

  3. Read the notes

    A report scores every competency, quotes the answers that cost you, and gives you a prep plan for the next session.

A report that quotes you, not a pat on the back

Every score links back to something you actually said.

  • Competency scores

    Weighted to the role you picked, so a system design gap counts more for a senior backend role than for a frontend junior.

  • STAR check on every story

    See which part of each behavioral answer was missing — usually the Result.

  • How you sounded

    Filler words, hedging, "I" versus "we", and whether you cited real numbers — measured from your words, and compared between the first and second half of the interview.

  • A prep plan

    The two or three things to practice next, and a skill graph that tracks them across sessions.
