I interviewed with 7 people! 5 of them were there in the conference room and 2 of them were over the phone. It was a good interview but very overwhelming because I didn't realize I was interviewing for 3 different positions at once.
Just a note to anyone who applies there:
When you upload your resume it will change format. So make sure you let them know you have the resume in the proper format at the interview, have enough copies for about 8 people.
