Uber Software Engineer interview questions

A recruiter was emailing me twice a year for two years about how interested he was in getting me in to interview, and if I was on the market yet. So when I finally decided it was time to start looking for my next role, I emailed him since I was interested in hearing more. He responded a month or so later after the roles I'd asked about had already been hired for, but pointed out that there were new ones out there now if I was interested. I said I was, and applied for several and followed up to let him know. Got absolutely nothing back at any point after that, even after following up again. What an absolute waste of my time. Also, their job app site is terrible. Why is there only a tiny, non-expandable text box to explain each role? Who designed this?

5 round of interview, 2 coding, 2 bq and 1 system design. The interview lasting for 5 hours. It is a virtual onsite interview and all 5 rounds of interviews are taking through zoom .
