First shortlisted with a telephonic interview. This was followed by a whole day of interview with various teams interviewing me. Began with a description of the role and the work the team does, questions on my projects and previous work experience, technical rounds on communication systems, C and some probability.

Interview process is simple and asked about the standard questions found on the internet. Design a rate limiter using sliding window algorithm. And interviewer is friendly. HR took time to respond and after all rounds they released the offer.
