There are only two rounds - first round is 30 mins and just an overall screening, second round includes 4 separate 30 mins interviews. The second round has some behavioral / circumstantial questions, but nothing too difficult.

I interviewed in early October. Had a great first round and the interviewer instructed me to contact the recruiter for HR related questions (timelines etc). I emailed her directly after - never heard back. Followed up 2 weeks later and nothing. I know the interview went great and I have no idea why I heard nothing from them following it.
