Niantic interview questions

Interviewed with Niantic in February of 2021 through a referral. The interview process is very long, but the recruiters I worked with were informative, always quick to respond to questions, and always quick to schedule and communicate next steps. Unfortunately they weren't able to hire me, but said they'd "keep me in mind", which they did, and a year later reached out again. I had a few more interviews, and then was given an offer.

Ghosting after scheduling the interview at preliminary stages. This has happened twice for same position in two different intances. First time, I got a reply from niantic recruiter asking to schdule for first round of basic introduction interview. I had submitted my availability but the interviewer for some reason didn't bother to join or respond after that. Second time I at least got chance to connect at first exploratory interview and was informed to expect first round of tech interviews in following week. But then again no further response or updates. One can only wonder what's happening? But I ain't gonna bother for next time!
