We’ve seen Mercor care less about polished small talk and more about whether you can defend the technical choices behind your recent work. In the candidate experience we reviewed, the interview immediately anchored on the resume and profile, then kept narrowing into the specifics of AI and machine learning projects. That pattern matters: the conversation wasn’t broad or generic, it was built to test whether your background is real, current, and technically coherent.
A recurring theme is that Mercor seems to value depth over breadth. Once the candidate mentioned recent roles, the follow-up questions kept drilling into implementation details, tradeoffs, and why certain decisions were made. That tells us the bar is not just “have you done AI work,” but “can you explain exactly how you did it and what you learned.” Candidates who can only summarize projects at a high level are likely to feel the pressure quickly.
We also notice that the process is designed to feel efficient, but that efficiency is itself a signal: Mercor appears to want people who can get to substance fast and stay there. The strongest preparation priority is to be ready to walk through your most recent AI or ML work in concrete terms, because the interview will use your own experience as the map and keep probing until it reaches the technical weeds.

The most memorable part of the process was how quickly it turned technical. This was an AI interview, and it clearly used my CV and profile to generate the questions, so the conversation felt tailored to my background rather than like a generic screening. It started with my most recent roles and then kept pushing deeper into the technical details as I answered, which made it feel more like a live technical discussion than a standard recruiter call. One of the first things it asked was what technical projects I had worked on that involved AI or machine learning, and from there it kept drilling into the specifics of my experience and the choices I made on those projects.
The overall flow was smooth and surprisingly natural for an automated interview. I was able to talk through my background, technical skill set, and relevant project experience without the usual awkwardness you sometimes get with scripted screens. There wasn’t a lot of process overhead, and the system seemed designed to get to the substance fast. For me, that made it feel efficient and modern rather than impersonal. I ended up accepting the offer, and the main thing I’d tell others is to be ready to speak concretely about recent work, especially AI or ML projects, because the interview will use your own resume as the starting point and keep probing until it gets into the technical weeds.
Prep tip from this candidate
Be ready to walk through your most recent roles in detail, since the AI interview starts from your CV and keeps probing technically. Have a clear explanation ready for any AI or machine learning projects you listed, including what you built and the technical decisions behind it.
