The interview process is exactly how others have described it here.

It consists of two technical interviews, one case interview, and one behavioral interview. The technical interviews should be fairly simple and easy for most candidates. One is a code test, and the other involves system design questions.

I suppose the case interview was the only reason I didn't get an offer, as I performed extremely well on the other three out of the four sections. I had prepared well for the case interview, but unfortunately, my interviewer was simply not a good interviewer. They were not enthusiastic, did not explain the problem clearly or what I was supposed to be doing, and did not provide any helpful feedback when I asked for clarification (despite being encouraged to ask questions).

I am about 100% sure that this interviewer was the reason I wasn't given an offer. So, as a fair warning, be prepared for these types of interviewers and keep your expectations low, as they might be particularly picky at this moment.
