What Karat outsourced technical interviews cost in 2026.

What Karat sells, and why it is quoted.

Karat operates a fundamentally different model from HackerRank, CodeSignal, and other assessment platforms. Where those tools provide infrastructure for hiring teams to conduct interviews themselves, Karat provides the interviewer. Karat is technical interviewing as a service: the company contracts with a network of expert interviewers, trains them to a standardised rubric, and conducts technical screens on behalf of hiring companies. The output is a structured rubric score, a written narrative report, and a hire/no-hire recommendation delivered to the hiring team within 24 to 48 hours.

Because the product is human interviewer time plus calibration, Karat sells it as a negotiated contract rather than a self-service plan. The assessment platforms on this site publish card-buyable tiers; Karat does not, so the only reliable Karat price is the one in your own quote. What you can control is the comparison: know your in-house cost per screen before the sales conversation starts.

Our model: the in-house cost of the same interview.

This is our model, not Karat data. Every input is visible so you can swap in your own. Loaded hourly rates are the levels used on our technical phone interview cost page (mid-level $90, senior $122, staff $176 an hour, built from base salary through a loaded multiplier). An in-house screen consumes 90 to 110 minutes of the interviewer’s time once prep, debrief, ATS notes and context switch are counted. With Karat, the hiring team still spends 5 to 15 minutes reading the report and deciding whether to advance the candidate.

How to read it: the break-even column is the in-house screen cost minus the report-review time you still spend. A Karat quote below that figure is cheaper per interview in engineer-time dollars; a quote above it can still be worth paying, but the case then rests on interview capacity and signal consistency rather than on per-screen saving. To rerun it, multiply your interviewer’s loaded hourly rate by 1.5 to 1.83 hours (90 to 110 minutes), then subtract the rate times 0.08 to 0.25 hours (5 to 15 minutes).

The engineer-hour-reclamation case.

The structural case for Karat is engineer-hour reclamation. In active-hiring engineering organisations, the binding constraint is rarely dollar budget; it is engineer-interview-hour capacity. Engineers in active interviewing rotation lose 8 to 24 hours per quarter to interview work, producing measurable declines in shipping velocity and elevated burnout risk. Adding hires to the team requires more interview-hours, which the engineers don’t have, which delays hires, which delays shipping.

Karat breaks this constraint by outsourcing the first technical screen entirely. The engineer never sits on the call. On the model above, each outsourced screen returns roughly 75 to 105 minutes of senior-engineer time to product work, worth about $150 to $215 at $122 an hour. The higher your interviewers’ loaded rates, the higher the quote you can accept: with staff-level interviewers the break-even rises to roughly $220 to $310 per interview.

What drives a Karat quote.

Karat does not publish rate cards or volume tiers. These are the inputs that shape a quote, and the questions worth asking so that two quotes can be compared like for like.

Once you have a per-interview figure, put it next to the break-even column in the model above for the level of engineer who would otherwise run the screen. Multiply the gap by your annual screen volume to see the yearly cost or saving in engineer-time dollars, then weigh that against the capacity and consistency benefits below.

What Karat pays its interview engineers.

A Karat interview is priced like professional services rather than like a $10 to $30 software seat because the underlying cost is human interviewer labour, not software. An experienced engineer runs the live interview and writes the report, and that labour, plus Karat’s platform, rubric calibration, report QA and margin, is what the client’s fee has to cover. Karat does not publish what it pays its interview engineers.

For the buyer, what the Karat interviewer earns is context, not the comparison. The relevant comparison is still the in-house engineer time the screen replaces, which is what the model above prices.

Signal consistency: the second value driver.

Beyond engineer-hour reclamation, Karat’s value proposition rests on signal consistency. In-house technical interviewing produces calibration drift over time: different engineers calibrate differently, rubrics get applied inconsistently, and the hiring bar can shift quietly across reqs. Karat’s standardised rubric, professional interviewer pool, and centralised calibration process aim to produce more consistent signal across candidates.

You can price that benefit with your own data. Count the candidates who passed your in-house technical screen last year but failed at onsite, and multiply by your onsite cost per finalist ($3,200 to $7,800 on our model). Every false-positive onsite a more consistent screen prevents saves that amount, so even a small reduction can outweigh the gap between a Karat quote and the in-house screen cost. Run a pilot and measure the change rather than assuming one.

The signal-quality benefit is conditional on the in-house team trusting and using the Karat report. Teams that adopt Karat but second-guess every report (rerunning in-house screens on Karat-passed candidates) don’t capture the cost saving and add cost. Successful Karat adoption requires explicit calibration with Karat upfront and discipline about treating the Karat report as the screen, not as one of several inputs.

Where Karat doesn’t fit.

Karat is not the right tool for every hiring situation. Three patterns where the cost case fails. First, low-volume hiring (under 50 technical screens per year) where the per-interview fee dominates and the engineer-hour reclamation doesn’t compound enough to justify the contract overhead. Second, highly-specialised hiring where the in-house team has unique domain expertise that the Karat interviewer pool can’t match (cryptography, embedded systems, niche language hiring). Third, early-stage startups where in-house calibration with founder-engineer involvement is part of the hiring process by design.

For these patterns, in-house technical screening or assessment-platform-augmented in- house screening typically wins on cost or signal quality.
