Google

The interview process was fair, given the skill level I was at. However, I didn't prepare enough, so I wasn't ready. It's very long; be prepared to solve problems for 5 hours, which can be kind of draining.

The process was quite rigorous, but with enough LeetCode preparation, it is definitely doable. Other than that, they asked a few Fermi questions, standard interview questions, and normal background questions.

Good. It is something that they guide you through their office and help you know their working culture to examine the match between you and Google. It is more like communication to collaborate on a topic.
