I sent in my resume on a Thursday, received a phone interview request (with an availability calendar attached) on the following Monday, scheduled a call for Friday the same week, so roughly one week between my application and our first talk. Emails were very friendly and almost casual (but still professional), and so was the phone interview. My interviewer briefly introduced herself, then asked me to do the same. We talked about the position, the reasons for my being interested in it, about team sizes and culture, and she asked some questions here and there. The overall feel wasn't very much like a strict, structured interview (although I am sure it was in fact very structured), but it felt more like a conversation in which my interviewer was genuinely interested in what I had to say. She explained the next steps (a QA assignment via email, and then potentially an on-site interview) and asked for any remaining questions. I had none because she had answered all of them in the course of the interview already. Right after the phone call, I got the QA assignment (which basically asks you to describe how you would do QA on a specific object). I didn't end up finishing the assignment because I got another offer that I took. When I communicated this to my interviewer, she was very friendly about it. Overall very friendly, professional and positive interviewing experience.
