It's hard to explain. I spent about a year in my last job validating a code migration a different vendor had done for our client. It's not really the same as what I'd be doing at this new job, but there are similar principles at play.

The job is basically entry-level testing (0-2 years experience, the ad - which was otherwise inaccurate -said). The technical interviewer did mention that experience wasn't necessary and that they regularly interview people with literally no experience - they just look for people with the right mindset.

She seemed to indicate that my technical background was a plus, and I definitely showed that I understood what the job required.

Still, in the first interview, the HR woman noticeably hesitated before giving a salary range, indicating that she was probably aware that it would be a pay cut for me (also, if HR feels the need to give a number first, that's probably a bad sign in terms of expectations of overqualification). As I said above though, going into the technical interview I really didn't care if I got the job or not, and it wouldn't kill me if I didn't get it, especially since it would be very obvious that the reason wasn't underqualification.
