OA -> 1-hour technical phone interview -> recruiter chat -> final round.

The response times between each portion were pretty long, so the overall process felt unorganized. I waited two weeks to receive a response after my phone interview.

The final round consisted of 2 technical interviews and 1 personality interview. The technical interviews weren't too bad, mostly medium-difficulty problems, although there were more difficult follow-ups. I wasn't asked any OS questions.

I would recommend brushing up on runtime/space analysis and data structures.

The phone interview was about duplicate files.
