The first round was a video call with other engineers in the team. The conversation was rather shallow as we didn't delve into the details I consider important to gauge the candidate's experience, but as there was going to be a take-home assignment, I didn't push too far. Key points were: 1/ considering using Rust going forward, 2/ they're not wedded to any technology, but asked for specifics on nix, which wasn't mentioned in the job description. The take-home assignment was unrelated to the position, but I entertained it, as it sounded fun to do. Provided my solution within the timeframe, but didn't get a response in two weeks, so I followed up. The recruiter hadn't forwarded my solution to the team and asked for more time for them to review it. After more wait, they provided feedback that was also unrelated to the position. They seemed to value over-engineered solutions over the simple but functional code that a seasoned engineer can create. Considered replying, but decided not to. If you're an experienced engineer, don't waste your time here – their "senior" team is comprised of 20-year-olds who don't understand what they are looking for or how to assess it.
