Karat Practice Guide: What to Expect & How to Prepare (2026)

A Karat interview feels different from every other screen, because the person on the other side is not a company engineer who happens to be free at 2pm — it's a professional interviewer who does this dozens of times a week, follows a structured rubric, and will not be charmed or rushed. Companies like Indeed, Intuit, and several others outsource early technical rounds to Karat for exactly that consistency. If your prep has been built around silent judges and timers, this page recalibrates you for a human who grades your thinking in real time.

The format, from the candidate's chair

Karat sessions run 45 to 60 minutes over video, with a shared code editor. A typical SWE session has one or two coding problems, chosen from a large calibrated pool, and the interviewer is watching the rubric dimensions as much as the code: problem decomposition, communication, code quality, testing discipline, and how you respond to hints.

That last dimension matters more here than anywhere else. Karat interviewers are explicitly instructed to help — and to note whether you use the help well. A candidate who hears a hint, integrates it, and moves forward scores higher than a candidate who ignores three hints and grinds silently. Silently grinding is a LeetCode habit. Karat punishes it.

There's usually a short wrap-up with time for your questions. Some companies add a second Karat session or pair it with their own onsite loop afterward.

What the rubric actually rewards

Having read plenty of candidate write-ups about Karat sessions, the pattern is clear about what moves the score:

• Thinking out loud, continuously. The interviewer can only log what they hear. Thirty seconds of silence is a blank cell in the rubric.
• A clean first plan. State a brute force, state its complexity, then improve. Karat interviewers consistently report that candidates who verbalize this progression score better even when the final code is identical.
• Self-testing before being asked. Run the example inputs, then propose one edge case unprompted. It signals engineering maturity that fresh graduates rarely show.
• Hint uptake. Treat every hint as a gift, not an interruption. "That's a good point — so I could keep a running max instead of re-scanning" is the sound of points being earned.

The one-week Karat crash course

If a Karat session lands on your calendar, this sequence gets you ready fast:

• Days 1–3: eight medium problems, one per 30-minute block, with one non-negotiable rule — narrate everything. Standalone voice recording helps; listen back and kill the dead air. Pair this with the Two Sum walkthrough for the narration script.
• Day 4: hint-response drills. Solve a problem with a friend (or an AI assistant), and instruct them to drop one hint at a fixed point. Practice the acknowledge-integrate-continue reflex until it's automatic.
• Days 5–6: two full mock interviews at 60 minutes, camera on, one or two mediums each. Review for rubric behaviors, not just correctness.
• Day 7: rest. Karat interviewers can hear a tired candidate.

Where the difficulty actually sits

Honest take: Karat problems are rarely the hardest part. Medium-level, well-specified, no trick input formats. The difficulty is performative — sustaining clear narration for an hour while solving under observation. That's trainable, and it's exactly the skill most solo-prep candidates skip. Tools that force the loop help here: Easy Code Interview's workflow — problem on your main screen, short answer plus detailed explanation arriving on your second device — doubles as narration practice, because explaining why the given answer works, out loud, in your own words, is the same muscle Karat's rubric measures.

Frequently Asked Questions

Who uses Karat for interviews?

A rotating set of mid-size and large tech companies — Indeed, Intuit, and others have used Karat for early technical rounds in recent years. The client list shifts, so you may only learn it was Karat when the invite arrives.

Are Karat interviewers engineers at the company I'm applying to?

No — that's the point. Karat interviewers are professional interviewers employed by Karat, trained on a shared rubric. They don't know team details and can't answer culture questions; save those for the company rounds that follow.

How should I handle hints during a Karat interview?

Acknowledge, integrate, and continue — out loud. Hints are a designed part of the session and hint uptake is scored. Ignoring hints to work independently is one of the most common ways candidates underperform.

Is the Karat coding editor any good?

It's functional: syntax highlighting, basic editing, no execution in some configurations — you may be asked to trace tests by hand. Practice writing runnable-looking code without a judge confirming it for you.

What score does Karat give, and who sees it?

Interviewers submit a structured evaluation against the rubric, which the hiring company uses alongside everything else. You typically won't see a raw number; the pass/fail signal goes to the company.
