Navan interview questions

Applied for a MOPs role in the NYC office. Very strange and disorganized interview process. Whole process took 5 weeks till I was rejected. First spoke on the phone with the recruiter, which was a nice, pleasant conversation where it looked like my skills would be a perfect match. The person I would directly report to was on leave, so 2nd round was with the head of the department instead (They were overseas, so my only real option was to meet with them on a call very early at 6am my time). Weirdly, they had me do an assignment immediately after only the second round and then do a brief presentation (with the same person from the previous round. Again at 6am my time) for a 3th round, both of which I was told went well. The assignment took me about 4 hours and I was given 3 days to complete it. 4th round I met on Zoom with a cross-team collaborator based in the West Coast I would be working with, which I was told also went well. Things started get strange after that. I was told by the recruiter that the previous person I spoke with felt like he needed more time to speak with me due to an audio glitch my computer was having at the start of our other interview that made it begin 8 minutes late, even though we still chatted for the full 30 minutes during that call that we were supposed to... so the 5th round ended up being me speaking to the same person again, alone with one of his direct reports (also on the West Coast I believe), which turned it into a panel. The call started off great, but then I was asked a very intense hypothetical question on mass system updates by the same person from the previous interview that really would have required me to see how their marketing system was specifically set up (of which I had no provided context for). The person criticized my answer very harshly, with a very different demeanor from my previous conversation with him. It semi-felt like a gotcha question. The two people on the call also assumed that I had spoken with other people directly on the Marketing Ops team for context on their systems, of which I did not ( I had spoken with zero people on my direct Marketing Operations team at this point in the process and had no direct context for my day-to-day from people hands on with the actual Marketing Operations process with the company, so I was flying half-blind). I feel like the last couple questions they asked me were under the assumption that I had spoken with different people at the company prior to the 5th round (when I clarified this to them, they seemed confused). I was sent a rejection email the following week. It was very odd that I never spoke with anyone else in my direct section of the Marketing Department, nor anyone else on the East Coast or the NYC office (never even got to see the office). It was overall a very odd process and the 2nd half of 5th round was a very awkward vibe compared to everything else. I wish I didn't have to waste all that time on the presentation that early on only to be rejected without even ever meeting the rest of the Marketing team.
