Met recruiters at a hackathon and received a call for a phone screen a couple weeks after. Had a coding challenge, two rounds of HackerRank phone interviews, and a final behavioral interview.

The first screening round is a hackerrank challenge. For me it had a question related to counting votes (hashmap and aggregation), fairly basic. Was told that I would be moving on to the next rounds. There were 3 rounds with members from the team I was interviewing for. Fairly standard LeetCode questions. Know your arrays, strings and graphs and you should be fine. Recruiters were very helpful and responded quickly as I had different offers.
