They contacted me. Process took 2 weeks, at reference stage. Interviewers were all EMs, and largely focused at system design interviews with AI. At the end of 5 stage interviews, they asked for references then they ceased all communication.

HR emailed me a link to 2 tests: A lengthy IQ test and a shorter personality test. Then HR schedules a pair programming interview. (Still no contact with a human being). The description of the programming interview was that we would pair up to solve a real world problem. When I joined the programming interview with an engineer, he told me to use ChatGPT or Google any resources if I wanted as much as I need and then asked me to code LRU cache. It was not a pair programming interview, but me leveraging online tools as much as needed. I was caught off guard because I was never told about this setup before this interview, and did not have time to clear my browser history and chatGPT history. Plus I wasn't sure how me googling the code for LRU cache directly would affect my interview score because that would have ended up being a <= 10 min. activity. ( Note: My chatGPT history had a lot of personal medical questions leading up to this interview). I told him I know an OrderedDict can be used to do a LRU cache in latest versions of Python and I didn't want to ask Google or ChatGPT the exact interview question directly. He said "ok" and I assumed (incorrectly?) that he was agreeing with my hesitations on chatGPT/googling-ing the direct answer. So I proceeded to only get the API for OrderedDict and somehow used that to finish the LRU cache with 10 min. time left for questions at the end. That is, I never searched for the question directly. The interviewed did say "since you got a decent solution, I can sell you on the company" when I asked about the company culture at the end. So I assumed it was a "pass." The next day I got a generic "After careful consideration, we have decided not to proceed further with your application at this time. While we recognize your skills and qualifications, our current needs and role requirements led us to this decision" from the HR that I never spoke to once during the whole process.
