The problem was easy, with a medium follow-up. I was able to solve the first part, but I needed hints to optimize it. The interviewer looked like he didn't want to be there. He was a little rude and didn't make me feel welcome.

The interview process was pretty simple. I visited the on-campus recruiting booth and secured an interview a week later. The on-campus interview covered behavioral aspects and included one technical question, which was not too difficult.

I took a ride, and the app suggested a code on the road. I used it, and they sent me an email asking for my resume. Two weeks after that, they interviewed me over the phone and later scheduled another phone interview for the following week.
