Airbnb Software Developer interview questions

Phone screen interview for 45 minutes. Leetcode question, medium difficulty level. Interviewer was nice and professional, and received signals that I did well and would pass the phone screen round. However, didn't hear back from recruiter for any updates after the interview. Followed up twice but no updates.

Usual phone screen, followed up by a virtual coding challenge, then an on-site with a whole day of interviews, one of them was alien dictionary from leetcode (hard problem), also create a card game in react, the other interviews were a mix of behavioral and algorithms
