I applied through their website career page and I've had three technical rounds so far, all done online via Google Meet. One of their HR then updated me a few months ago that they are still in the midst of interviewing others, that's the last update I'd received from them.

Questions about past experience and then more in-depth questions based on those. Mostly computer systems-related, like "why is cache coherency important in a multi-core system?", and some of the easier ones like "what's the use of static, volatile, ...?"
