I was contacted through LinkedIn.

I then had two phone interviews. After they were satisfied, they invited me to a hiring event scheduled in Chicago for an in-person interview.

A "Meet & Greet" session was scheduled a couple of days before my actual interview. This gave me the opportunity to interact with team members, some of whom were on the interview panel.

The in-person interview consisted of four one-hour interviews. They were focused on problem-solving, writing programs, discussing approaches, and designing data structures.

The interviewers were very friendly and encouraging, guiding the entire problem-solving process.

Nothing specific.
