Hire better engineers
Stop wasting your engineers' time
Structured technical interviews. Run them yourself, or have our senior engineers run them for you. Either way you get a scored, auditable report the same day.
Alan demonstrated strong theoretical foundations but spent considerable time trying to prove whether the interview itself was decidable. Required moderate handholding on the manhole question, which he dismissed as "not a proper computational problem." Would have benefited from a whiteboard rather than an Enigma machine. Strong hire – assuming the role doesn't require social media presence.

What we do
We run your technical interviews
You send your candidate a link. One of our interviewers runs a live session with them in our browser IDE: real debugging in a working codebase, not LeetCode.
The interviewer records observations as they happen; the platform computes the score. The same day, you get the full report: verdict, checklist, code, keystroke replay.
Prefer to run them yourself?
Your engineers get the same library, rubrics and reports on plans from $99 a month.
How it runs
Your calendar stays empty
You send the candidate a link and read the report that comes back. Everything in between happens without you.
- 01
Send the candidate a link
Pick a role format, type an email address. That's the whole setup.
- 02
Read the report
Read the score, observation checklist, final code and keystroke playback the same day.
- 03
Make the call
We measure, you decide. Forward the report as-is to whoever needs convincing.
- Scheduling
The candidate picks a slot from live interviewer availability. Nobody plays calendar tennis.
- Prep
They get a brief before the session: what's assessed and how each question works.
- The session
A senior engineer runs it with them in our browser IDE, on camera.
- Scoring
Observations are ticked as they happen; the platform does the math.
- Write-up
AI can organize notes, suggest a draft and flag missed evidence. The interviewer makes every judgment, edits the draft and signs the report.
Who is interviewing your candidates
People who have shipped production systems for over a decade and spent years of it on the hiring side of the table.
Combined interviewing mileage across the pool: career sessions for some of the most demanding hiring bars in tech, plus every interview run on Coderbase.
We test what the job tests: unfamiliar code, a real bug, trade-offs that have to hold in production. If it doesn't happen on the job, it doesn't happen in our interviews.
Coderbase pays the best interviewer rates in the business and adjusts them each year for inflation. Interviewers can earn more through volume, quality and incentives. People who've run thousands of interviews for the most demanding hiring bars in tech don't moonlight for scraps, and paying them properly is how we keep them, so your next interviewer meets the same standard as the last one.
Customer story
"Your interviews and reports are excellent and really helping with the hiring project."
Tim Richardson · CTO, PayPlan
PayPlan ran its 2026 hiring push on Coderbase: 60 technical interviews across nine roles, 25 hires, and none of it on their engineers' calendars.

Candidate experience
An anxious candidate is a noisy signal
A candidate who bombs because they're terrified tells you nothing. We strip the anxiety out of the format so what you measure is ability, not nerves.
Prepared, not ambushed
Every candidate gets a prep brief before the session: what's being assessed, how each question works, what the timing is. No surprises.
A human in the room
A senior engineer who keeps candidates moving without giving the answer away. No bot voice, no lockdown spyware, no hidden test cases.
A no-penalty redo
When you enable it, a candidate can opt into a fresh second interview – you get both reports. The safety net alone calms nerves and cuts false negatives.
