It was pretty straightforward and quick. I received an email from my interviewer about a month after I had applied, and we set up an interview for the next day. There was only one round (no Hirevue), and I received my offer a few days later.

Had a one-on-one interview with the internship supervisor. It was pretty lax, and she was accommodating with my schedule to find a time to interview. She was pretty friendly, and told me all the following steps post interview as well that I should expect. I was interviewing at ADA for a marketing research and strategy internship.
