I applied through college or university. The process took 2 months.

its was an on campus drive, there were multiple rounds- coding, apti, hackathon part a, elimination round(online meet interview a DSA q was given whose ans was to be discussed and further optimise), hackathon part b(it was an 8 hr slack chat where code for part a was discussed and i was asked to make it thread safe and DSA Q were asked), final offline interview at the office.

DSA Q were asked such as a light bulb, one was bit manipulation, tree of life.
