They asked some pretty advanced questions for an intern role, more so than for a full-time position the following year. The interviewer didn't seem very engaged from the beginning of the conversation.
Had 1 virtual presentation and screening with HR, then 1 call with the hiring manager. This was followed by 3 days of on-site interviews. Day 1 was about 'your' (presumably the candidate's background/experience). Day 2 involved a presentation and a tour. Day 3 was a full day of interviews with a total of 16 people.
The interview process was good and went really well. You should prepare well and attend for the technical interview. The rest goes smooth. There were a total of 3 rounds: technical, management, and HR rounds. It takes 2 weeks time. Be prepared. All the very best.
