First, there was a phone screen where I was asked questions about CS fundamentals (data structures, mostly).

Then, I was asked to walk through a solution to an algorithm question over the phone.

Next, I had a take-home test which took me approximately 10 hours to complete.

Finally, I had an onsite visit which was approximately 7 hours in total.

I began by following a coding prompt that took a little over an hour to complete.

I was then interviewed by different parts of the company in 1-hour segments, mostly about data structures and CS fundamentals.

The interviewers had a pretty even balance of nice and aggressive personalities.
