Pursuit Mid-Level Role interview questions

Interview was easy, conversational, and behavioral. The weird thing was it was on a Saturday morning and there were a bunch of people in the office on Skype--red flag? The absolute sketchiest part was they wanted me to complete a very complex project for them for the "2nd round" interview and put it on their Google Drive--the kind of project that could eat up a whole summer-long internship. I said I'd bring a flash drive, as it was my product I spent many hours making. They really, really wanted me to put it on their system. I got a weird feeling I was being used for free consulting/labor and pulled out of the interview process, no longer interested.
