I first passed a phone interview, then went onsite.

The phone interview was typical, with some questions about hash tables and trees.

For the onsite interview, we first had a little tour around the company.

Then, there were two technical rounds, and I didn't manage to pass those.

My recommendation is to grab some snacks before the interview, as there is no lunch provided.

I spent a lot of time trying to explain that the complexity of building a priority queue is O(n), but the interviewer seemed unconvinced.
