Replace technical interview as a service

Your own engineers run the technical interview in a shared VS Code workspace, with a terminal and the Claude Code CLI. Codility Screen builds the shortlist, and every AI interaction in Screen and Interview is captured as reviewable AI activity.

Today’s failing approach: technical interview outsourcing followed by a second round

That’s two paid conversations before anyone makes a decision.

Keep the structure, drop the middleman

Codility Interview is a shared VS Code workspace your own engineers run. The tasks come from Codility’s validated library, or you bring your own. Your team sets the rubric, and every session ends with rubric scores, a transcript, playback and reviewable AI activity.

Codility Screen takes the shortlisting, your engineers take the interview

  • Today you run three stages: your screen, the provider’s interview, then the hiring manager round that happens anyway.
  • Codility Screen takes over the shortlisting the provider’s round does today, using role-relevant engineering tasks.
  • Your engineers run the technical interview in Codility Interview, with the candidates on the Screen shortlist. Your team does not spend interview time on candidates who do not fit the role.
  • The separate outsourced round comes out of your process.

One session, one record, nothing left to schedule.

Your engineers interview where they work

  • The session runs in shared VS Code, with a terminal, package installs, autocomplete and the AI Copilot. Your engineers see the candidate work with AI, the way they would on the job.
  • Whiteboard and system design happen in the same window, so architecture and code are not split across two tools.
  • Your engineers run the session on tasks from Codility’s validated library or on their own, and score against one rubric your team sets.

You watch someone work on a Monday, and they meet the team they’d join.

The record is ready when the session ends

  • Rubric scores, a full transcript, step-by-step playback and the AI activity log are there the moment the interview finishes.
  • Nobody chases an engineer for a scorecard.
  • And when a hiring committee reopens the decision six months later, they can see how it was reached rather than take somebody’s word for it.

Feedback in minutes, evidence that survives an audit.

What changes when the round comes back in-house

Technical interview as a service Codility Interview
Cost model Per interview, billed on passes and rejections alike One volume commitment across Screen and Interview, credits returned for cancellations
Who writes the questions The vendor’s standardized set Your tasks, your rubric, your criteria
Who the candidate meets A contract interviewer The team they would join
Turnaround Buyers report days Rubric scores, transcript and playback at the end of the session

When technical interview as a service is still the better buy

Some teams should keep it. If your engineers truly can’t give up the hours, or you hire in two short bursts a year, or nobody internally will own the rubric, a vendor that supplies interviewers earns its money. Codility Interview is for teams who’d rather run the round themselves and want it structured and recorded when they do.

What candidates say when your own team runs it

87% rate their assessment experience good or excellent
Fairness stays above 83% across every demographic group measured
Candidates in the bottom quartile still rate the experience good or excellent 60% of the time

Codility post-assessment candidate feedback survey, 48,000+ responses, Oct 2025 to Apr 2026.

“Codility has streamlined how we evaluate technical roles at Trimble. Beyond a great product and its proctoring features, their customer success team is responsive and dedicated, offering deep-dive support and guidance every step of the way.”

Questions buyers ask

A vendor supplies trained interviewers who run your first-round technical interviews and sends back a scorecard with a recommendation. Most buyers keep it as a filter and run their own round afterward, which is where the second cost shows up.

  • Billed per interview, and buyers report $250 to $350 a session
  • The interviewer isn’t on your team and doesn’t use your tasks
  • The promise is engineering hours returned
