Domande di colloquio presso Deepchecks

interviewers lack interpersonal skills. First step is a 30 min zoom call with the recruiter (could have been a 5 min phone talk, even though she is very nice) Second step was a 1.5 hour system design interview with the vp r&d, and a senior dev that joined half way through. The first question was to design a rate limiter, allow X requests from each customerID every minute. You should implement it with Redis and start out with: 1. Fixed-window algorithm (first X requests will take all of the capacity for the rest of the minute, so it's not good) 2. Make it better with a sliding window algorithm (this one will require o(X) for every request, so could be better) 3. Use a leaky bucket algorithm - have a counter for requests, and every minute reduce X from it. After that the senior dev has joined, and we discussed the architecture of something I worked on. He asked a lot of questions about it, which was a good sign. In the end, as we had like 5 minute until the end of the interview, I was asked if "I knew how to design their basic architecture". Then he explained an abstract workflow and asked me to do a system design for it. i thought it was some sort of a bonus question, as we had like 3 minutes until the end of the interview. I suggested a possible architcture, we discussed the bottlenecks and possible solutions, as it was very rushed, i didnt provide the right solution

A zoom interview of 20 minutes with the recruiter (which is my opinion kind of too much - most companies conduct a phone call) but the call was concrete and the recruiter was nice and willing to answer questions. There are 2 more technical interviews and I had an interview with the manager. The interview was with him and with another senior developer from the team. Looks like they don't even know what they're looking for. The software engineer was short on time and I was urged to speak fast and concrete which is kind of awkward and disrespectful. They also wrote things to each other about me during the interview and when I was "stuck" they just bothered to watch me. At the end of the interview the manager was very pressed to leave the meeting (although the interview finished earlier than expected), I just knew by the whole attitude that I didn't pass.
