TL;DR
CoderPad live sessions and screen assessments use completely different detection methods. Live sessions record keystrokes in a playback timeline but do not monitor your desktop, apps, or browser tabs outside the editor. Screen assessments track tab switches, flag IP changes, run plagiarism checks, and can enable webcam snapshots. Browser-based AI tools get caught because they live inside the browser that CoderPad monitors. InterviewMan at $12 per month on annual billing runs as a desktop overlay outside the browser entirely, so tab tracking does not fire and the tool never appears in screen recordings or webcam snapshots. It includes over 20 stealth features at the base price with 57,000 users and zero confirmed detections. The key to passing CoderPad with any tool is typing code yourself at normal speed, since the keystroke playback catches pasted solutions and sudden jumps from stuck to solved. Test your full setup on coderpad.io/sandbox before any real assessment.
i ran a tool through two live CoderPad rounds and one screen assessment last week and nobody caught anything. i need to write this up because my buddy Jake was not so lucky and what happened to him is what pushed me to actually do the research before trying it myself.
Jake had a take home CoderPad screen assessment for some fintech company. He used a Chrome extension during it. What Jake did not know, and this is the part that still makes me angry for him, is that the company had turned on webcam snapshots. The recording caught him looking at his second screen through half the test. One sentence rejection email the next day. No details, no appeal, nothing. Just gone. When he told me i felt sick because i had two CoderPad rounds coming up and i was already thinking about using something similar.
so i spent that weekend at Marcus's apartment. Marcus interviews candidates on CoderPad every week for his company so he knows exactly what shows up on his end and what does not. i basically interrogated him for three hours lol. the single most important thing he said was that live CoderPad sessions and screen assessments are completely different and almost everyone confuses them. Marcus told me on a live call he sits there watching you type and the entire session gets saved into a keystroke playback. he said he busted three people last year because the playback pattern is always obvious, a candidate sits there stuck for two full minutes and then suddenly a perfect solution appears in ten seconds. pasted code shows up, cursor speed is visible, the whole typing timeline is recorded.
but then he told me something that changed everything for me. during live sessions CoderPad records nothing on your desktop. not your apps. not your browser tabs. nothing outside the editor window. i actually pulled up their documentation on his laptop and confirmed it right there. i felt like such an idiot for closing every single application on my computer before my first ever CoderPad round lol.
now screen assessments, thats what got Jake. those track tab switches, flag your IP if it changes, run your solution through plagiarism checks, and if the company enables it they capture webcam shots to verify you are the same person who started the test. Jakes company had all of that on and he walked in blind.
i finally asked Marcus the question i had been building up to all afternoon. what about AI tools. He told me CoderPad has no scanner that looks at extensions the way HackerRank does. No fingerprinting engine that reads your code and decides whether AI wrote it. What trips people up is the indirect stuff, pasting big blocks into the editor, leaving the tab during a proctored assessment, weird timing jumps from stuck to solved in seconds. He also mentioned they started pushing follow up questions designed to expose people who paste code they do not understand, the interviewer just tells you to change the approach and if you freeze thats it.
after talking to Marcus i crossed browser extensions off my list entirely. Sensei AI at eighty nine a month and Cluely at ninety five with their stealth addon both run inside the browser which means on a proctored assessment the proctoring can see them. That is literally what happened to Jake except his was cheaper and even more obvious.
i went with InterviewMan at twelve bucks a month because it runs as a desktop overlay outside the browser entirely. Tested it on two live CoderPad rounds first. Tab tracking did not fire because InterviewMan has zero connection to the CoderPad tab, it just floats on screen as its own thing. i had Marcus review a mock playback and he saw normal typing speeds because i wrote every line myself, just glanced at hints between keystrokes and coded things my way. Then i used it on a real screen assessment where webcam captures were enabled. Went through every snapshot frame afterward. Not in a single one. 20 plus stealth features at the base twelve dollar price, 57,000 users, 4.8 stars. I spent an hour on reddit and discord after that looking for anyone who got caught with it on CoderPad or elsewhere and found nothing.
before any CoderPad interview go play around at coderpad.io/sandbox and test your full setup there. If your round is a screen assessment just ask the recruiter what proctoring they use because most will tell you. And the thing Marcus drilled into me that i keep coming back to is that on live calls the human rewatching your keystrokes catches more cheating than any automated system ever will.
