I was screened by the VP of Engineering and then sent an architecture challenge that asked me to design a dbaas with scalable instances of the Qdrant engine. I spent about 2-3 hours thinking of solutions and drawing out diagrams, then had a video call with one of their Senior Engineers to discuss my approach. It was a fun conversation and seemed to go well. I had my interview at 7am on a Tuesday (time zones) and they said they'd get back to me by the end of the week. Two weeks later, I had to directly email that engineer to ask for an update. They'd gone with someone who was a better fit and failed to update me. Very unprofessional.

The interview process was not long, a call with the recruiter followed by an interview with the hiring manager, and a take-home challenge, The process was seamless, but scheduling was somewhat unclear. The interview with the hiring manager was good, I took the home challenge and went to the next step, an interview with two engineering managers, which I didn't enjoy. One of the managers constantly interrupted me while I was talking and always gave me comments like, 'This is not enough,' or 'This thing is missing,' etc. I haven't heard back from them after the challenge interview.
