I was contacted on LinkedIn by a university recruiter about an opportunity. I was offered a first-round interview over Skype. The interview went well.

I was asked a variety of questions, including generic interview questions and technical questions.

Less than a week later, I was contacted about a final-round interview out of town. However, I was asked to fly cross-country with less than two days' notice.

After a couple of days, the recruiter set me up with a different position located in America. The interview took place in Redmond, but due to the snow, the interviews needed to be conducted virtually. I was interviewed four times, with each interview lasting about an hour. I was mainly asked technical questions and coded a couple of solutions.
