I applied online. The process took 3 months.

The interview is quite long and demanding, and I recommend taking it only if you are fully aware of this and have strong motivation to join the company. Initially, you are given a set of tasks that test logical-mathematical intelligence, as well as purely algorithmic or behavioral questions. Then there are three interviews: one behavioral, one logic-based, and a final technical one, covering all topics related to computer science. Overall, I found it enjoyable and different from the usual online assessments of other big tech companies.

I cannot say anything about it as I have signed an NDA.
