The interviewer cockpit during a live review: a code diff with an inline conversation and private interviewer notes, next to live candidate status and a scored findings checklist.

See the real product: diff to live interview

Real screens, about a minute. An interviewer imports a diff, prepares one reusable template, and creates a candidate session. The candidate joins from a link — no account — and the comment lands in the cockpit live.

Start the demo with a diff

Create one template. Run one session per candidate.

  1. 1

    Create the template

    Paste or upload a Git diff. Add the candidate-view description, redactions, expected findings, scores, private notes, and simulated checks. Frimbim saves this preparation as a reusable template.

  2. 2

    Create a candidate session

    Create an isolated session from the template. The candidate opens a private link, chooses a display name, and reviews the diff without an account or repository access.

  3. 3

    Run the interview

    Candidate comments appear in the cockpit when they are posted. Mark expected findings, add scores, and complete the evaluation before you archive the session.

What each side sees

The cockpit and candidate view show the same session. Interviewer-only material is never sent to the candidate's browser.

The candidate experience

Two candidate comments anchored to exact diff lines — one asking about a masked secret in the line above
  • A PR-style diff — file tree, description, checks
  • Inline comments on exact lines
  • Independent navigation, at their own pace
  • No account — just a private link

The interviewer cockpit

The cockpit score panel: expected findings with points and a running total
  • Expected findings and private notes inline
  • Candidate comments arrive live
  • A findings checklist with a running score
  • A read-only observer link for a colleague
  • End the session, finish evaluating, archive

Screen sharing

“Open that file. Scroll down. Go back.”

The interviewer controls the shared screen. The candidate cannot navigate or comment independently, and the review is not recorded on the diff.

frimbim

The candidate navigates, investigates, and comments independently.

You follow along in the cockpit and evaluate the actual review.

See how candidates reason about unfamiliar code

A review exercise can show how a candidate:

  • understands unfamiliar code
  • identifies bugs and risks
  • separates important problems from minor preferences
  • reasons about architecture and maintainability
  • communicates criticism
  • asks for missing context
  • discusses trade-offs

Frimbim does not score candidates automatically. It gives interviewers a consistent environment and rubric for evaluating the review.

Practical resources

Design the interview before you run it

Use a realistic diff, decide what evidence matters, and give every candidate a comparable review environment.

How to run a code review interview

A practical guide to choosing a diff, writing a rubric, structuring the hour, and evaluating consistently.

Frequently asked questions

Does the candidate need an account?

No. They join through a private link and choose a display name.

Do I need to connect a repository?

No. Frimbim works from a pasted or uploaded git diff.

Can I reuse an interview exercise?

Yes. Create separate sessions from the same template.

Can candidates edit the code?

No. Frimbim is for reviewing code, not implementing changes.

Can candidates see private findings or notes?

No. Interviewer material stays private.

Can colleagues observe an interview?

Yes. Share a read-only observer link.
