The interview process consisted of:

• 1 HR call
• 1 online test
• 1 phone screen
• 1 on-site interview

For the on-site interview, there were 3 rounds in the morning. This was followed by lunch with 2 employees, which was explicitly stated to be not part of the interview process. I did not make it to the afternoon rounds.

The interview itself was conducted professionally, but the HR coordination was a mess. I had to interact with 4 different HR people during the process, and it was no surprise that something went wrong.

On the day of the on-site interview, I was instructed to go to the wrong building in the morning. The interviewers were given a very out-of-date version of my resume, which created a lot of confusion (I sent them my latest resume early in the process).

I got the impression that they interviewed a lot of people and either didn't have the resources or didn't bother to make the process smoother for the candidates.
