Standard process. Technical interviews: * One phone interview. * On-site: Five back-to-back interviews. On-site, it was a bit chaotic. You could see that the interviews were business as usual. Even so, everybody was very nice and open to answering

On-site followed by one phone screen round, rejected later. The interview questions seemed basic. However, higher skills were expected, such as large-scale system design and professional coding proficiency.

Many different rounds. Interviewed by 5 people for 45 minutes each. Interviewed based on role-specific fit and company-related fit. The interview process is well-documented on many different websites. I recommend you practice coding beforehand.
