Google Creative Specialist Interview Questions

I was first contacted by an HR person, then had a phone call with someone from the department I'd be working in, and then an on site interview. I stopped here at the process, but had I gone further, there would've been a few more on site interviews. Overall the process was really long and unsatisfying. HR took a lot of time to get back, and the person who interviewed me didn't appear to have much experience with interviews. The feedback I got from it didn't make much sense.
