I applied online and there were a number of rounds.
The first two technical interviews were with engineers that were helpful and easy to talk with. The last behavioral interview was slightly awkward like they did not want to be there and it ended early.
The difficulty of the technical interviews were average. The coding session is performed on your own development platform so make sure to pick something you are comfortable using and debugging with. Both are very collaborative.
Behavioral interview had very standard questions. (past challenges, project you are proud of etc)
I was given a rejection email 1 week after the virtual onsite. After spending a good amount of time on this process I would have liked to get some feedback on why my application was rejected. However after multiple times contacting the recruiter there was no response. It is disappointing to see companies do this.
API design: Payment system like CashApp, PayPal etc
Implement some of the API you designed
