OpenAI Member Of Technical Staff interview questions

The most frustrating interview process I've ever had. I was contacted via a recruiter. I applied and made it through the screening stage (two interviews) and did the next session, where they told me what to expect in the main loop. But then... crickets for four weeks and counting. During that time, and occasional pings from me, I got one reply from the coordinator that they were having headcount discussions and saying they would follow up, but they never did.
