Does Codility Track Tab Switching or Detect AI?
ok so i lost a $180k offer over a extensie Chrome four months ago and i am inca not over it. I was running this browser tool during a Codility test that i thought was just a normal timed assessment. Turns out the company had inregistrare de ecran turned on and nobody told me. Got a one-line recruiter email the next week, "irregularities observed during the assessment review." I sat in my car after reading that email for probably ten minutes before i drove home.
That weekend i went to my coworker's place, he runs Codility hiring at his company, and i practic refused to leave until he showed me everything. He pulled up the hiring dashboard on his laptop and walked me through it while we ate pizza. The tab switching part freaked me out first, every time you leave the test tab when proctoring is on, Codility logs it. When you left, how long, how many times. He said the hiring team sees this timeline sitting right next to your code and most managers look at the flags before they read a single line. A couple quick switches probably wont kill you, he told me interviewers look at context, but if you leave for thirty seconds before each problem and come back with clean code that pattern jumps off the page.
Then he showed me the inregistrare de ecran viewer and i felt dumb. When my test loaded it asked me to pick between sharing a tab, a window, or my whole desktop. I picked tab thinking that was the safe choice and it nu am matter because my extension was IN the browser lol. My coworker said if you share your whole desktop with ChatGPT open in another window the recording just sees ChatGPT sitting right there. Tab-only sharing logs the switches but nu poate see where you went, ceea ce e better but my extension was visible in the browser either way so it nu am save me.
Then he brought up paste monitoring and sincer that was the scariest part. That runs on every Codility test, proctored or not. Code that appears without being typed e semnalizat with a timestamp. My coworker said their plagiarism engine checks against past submissions, GitHub repos, Stack Overflow, and in 2025 they added AI output pattern matching too. Typing rhythm matters, if you sit there slow for twenty minutes then suddenly fifty clean lines appear in ninety seconds nobody reviewing that believes a human wrote it under pressure. That described Jake from my study group almost exactly, he had the same pattern on his CodeSignal and got thrown out.
The thing my coworker said that de fapt calmed me down though. Codility runs in the browser. The proctoring watches the assessment tab, webcam, and inregistrare de ecran. Thats the wall. It nu poate scan what processes are running on your machine. A aplicatie desktop that never touches the browser page, Codility has no mechanism to detect it. My extensie Chrome a fost prins because a fost inside the same browser Codility was recording. A reviewer saw it in a frame before any automated system even flagged anything.
After that disaster i switched to InterviewMan at twelve bucks a month annual. Desktop app, 20 plus functii stealth baked into the base price. Used it on one proctored Codility and one unproctored since switching. Zero flags on either. Am verificat my own inregistrare de ecran frame by frame after and the overlay was not there. Hides from captura de ecran, dock, Activity Monitor, lista de procese. My typing looked normal because i read the hints and wrote code my own way with deletions and corrections and the normal mess you expect to see from a real person.
57.000 de utilizatori, 4.8 stele din 257 de recenzii. I searched in mod specific pentru oricine a fi prins on Codility with InterviewMan and nu am putut find a single report. Twelve bucks with everything included, no seventy five dollar stealth addon like Cluely charges and no ninety minute session cap like LockedIn at fifty five.
Before your Codility figure out if proctoring is on. Some companies never tell you. Run your own inregistrare de ecran during a practice session and watch the footage back. If you can see your tool the hiring team can see it too. I learned that the hard way and it cost me a hundred and eighty thousand dollars.
