I applied online and was contacted by the recruiter. I had a total of two technical interviews. The first interview was conducted via Google Hangout, and the second was a phone call.

The onsite interview took about one whole day, from 10 am to 4 pm. There were 5 rounds in total: 4 technical questions and 1 about your research project.

After your resume is accepted, you will take an online code assessment. Then, a few rounds of virtual phone interviews will be waiting for you. I'm not sure about what happens later, because I didn't pass the second round.
