So today I had a second interview with an in-bound call center, it's a sales like position, answering the phones for certain infomercials. The first interview was on Tuesday and it went so well, they called me 3 hours later to schedule the second interview. Then the interview today happened and I was so happy and excited. Then I go in, and he asks me just a few questions like why I think I'll be successful and a about my resume and any sales experience, I felt I was eloquent in my answers. But he keeps asking me if I have any questions, literally probably 7 times in the 20 minutes we talked. I felt so stupid that I didn't have any questions but the girl in the first interview answered every question I had really well and I told him that. It ended with him telling me the next steps and I asked him how long until I would hear something and he said one to two weeks. Given how quickly they let me know about the second interview I took this as a bad sign. Am I just overthinking things or does it sound like it went kind of badly?

@naangel- Thanks so much, it really makes me feel a little better. I feel stupid in interviews too when they ask if I have questions, I always have a list prepared but they usually cover it!
