I had one 30-minute screening interview, and in a couple of days, I got an email with an invitation to a full interview day.

An interview day is 4 interviews in one day, each 1 hour long, with 30-minute breaks after each.

First part of each interview was about introduction, where I was asked to describe some important or critical functionality I developed for my past project.

On the first 3 interviews, there was a difficult coding challenge where I needed to talk to interviewers and clarify details.

The last interview was about system design, again, nothing super difficult. I designed an API with user sessions handled by many machines.

Pleasant experience overall, and all interviewers were quite friendly.

Did you have conflicts during code reviews?
