Received an email from the recruiter with some helpful tips how to prepare. I have not been practicing leetcode questions but the one I got was easy... if it was in python (was not an option)

After the university Hackerrank test, I received an email in about a week to do a 90-minutes phone interview. The questions were moderately tough compared to other FAANGULTAD interviews. The first interview went well and I was able to come up with a working solution within the given timeframe. The interviewer seemed to be satisfied with the solution and I proceeded to the second round. The second interview didn't go as expected though. The interviewer was nice but was inexperienced at interviewing candidates. I usually try to brainstorm a few ideas, discuss my solutions with the interviewer, and pick the best solution and code it up. However, whenever I verbally expressed my thought process, the interviewer intervened and asked if this is the best and tried to nudge me down towards his way of thinking. I really appreciate that he was trying to help, but not everyone's thought process works the same. I could've ultimately arrived at the same optimized solution but because the interviewer kept interrupting throughout my initial brainstorming stage, my thoughts got tangled up and did not perform too well. I was able to get to a working solution, but I think the second interviewer was dissatisfied that I couldn't think in his way immediately. I think Airbnb should train interviewers better to get the most out of their candidates.

Hacker rank -> virtual onsite -> onsite. They usually got back within a week of the interview. The technical questions varied a lot but were usually difficult. The office is really great!
