Started with a zoom call with the hiring manager that was pleasant, then another call with the recruiter basically just asking if I'd like to keep interviewing. I was told the next round would just be a coding round, and then a take home project. I submitted my availability and then they threw 4 hours of interviews on my calendar for a single day. Not that it was unprecedented, but it was not communicated to me that this would essentially be the "virtual on site" interview. I asked to reschedule some of them so I could make time, but was met with silence. I went into the interviews anyways, the first two were pretty simple coding exercises, followed by one short conversation, and the interviewer emailed me the prompt for the take home assignment. Fourth interview was a behavioral with the head of Quality Engineering. The meat here is the take home assignment, which apparently I was the guinea pig for. The prompt was to essentially vibe code a HIL test management and dispatching stack, and then present it and ask questions about it. The prompt was pretty explicit about what they wanted, don't over engineer it, do what the prompt said. When I presented it, it worked for all the test cases, they all indicated that they were satisfied with what I had built. However the feedback was that I did not dive deep enough into some aspects of the manual and automated test side of things, and therefore did not get an offer. Feeling a little slighted because the prompt was to vibe code something that would take weeks to build out and make really robust, and be familiar enough with that you know how it works, the edge cases, and then to not be satisfied with a candidates familiarity with a code base they just AI'd like 2000 lines of code for at your request is a little ridiculous. My feedback is - if you want someone to demonstrate their programming skills on a complicated system, and then show off their ability to understand how it works and how to test it, give a stripped down set of requirements, have them write it themselves, and allocate more time so it can be done. The expectation that someone is going to be able to allocate the time to become intimately familiar with code in 2 days while working a full time job is ridiculous. Either simplify it or just do a more classical code interview.
