Google

First of all, they asked me to explain my current situation and background. In a next step, he asked me to explain the solution and write programming code on the Google platform, given certain problems.

Professional and enjoyable, though not as intense as I expected. It was definitely too lengthy and time-consuming. It would be much better if the interview process didn't always have to be 4 or 5 rounds, but I do understand why.

5 minutes asking about resume/ 10 minutes walking through an algo question, and 10 mins for another one/ 10 min self introduction/ 10 min letting me ask questions about company.
