Stack Overflow Senior Software Developer interview questions

i interviewed for SO in the summer 2022, and must say it was one the best processes I had in this round of interviews. The technical interviews were comprehensive without being insanely extensive. Computer science based, but not pointless memorization of leetcode exercises. Hands-on system design, with real world examples but also open-ended and conceptual. Behavioural questions that really made sense. Communication was always clear, frequent and flexible. I always felt accompanied through a fun process, rather than a boring or stressful barrier to the company. The company, well, is Stackoverflow :)

The interview process is easy although quite long with many steps. The interviewers are nice people and the conduct the interviews very professionally. However, HR is just horrible, they missed some of my emails with some questions and never replied. Then after wasting a long time completing the whole of their process they just don't write back. I guess I should take silence as no offer, but in my more than 10 years doing interviews I have never seen such a rude company that doesn't take the hassle of even writing a line to say you don't have an offer. I have sent them a some emails to get some feedback but after a couple of weeks I think it's time to give up. In fairness I read exactly the same already in other Glassdoors reviews, but I thought it to be maybe some exception, but I was wrong I think they don't write back after having completed the whole interview process.
