I applied to a job online in the very beginning of the month. The next day, I was contacted by an HR rep at the company and pre-interviewed over the phone. During this conversation, he asked me my salary requirements. I wish I had given a range, but instead I blurted out a non-padded number. He replied, "I think we could get close; probably to $____ ($5k below the number I stated). I felt it was too early to be entering into salary negotiations since I didn't know enough about the job, which I also wish I would have stated. Instead, I said "I'll have to consider commuting costs and all." We moved on and he scheduled an in-person interview with me for the following week.
It went really well and a little less than two weeks later (two days ago), I got a call that they want me back for a second round of interviews. They said I'm one of three candidates they're asking back and he asked me if I was still interested. I stated I definitely was and we hung up.
The NEXT DAY, I found out from my current employer that I got a small raise as a result of my year-end review. This essentially changes my salary requirements by about $3k. I'm expecting a call today from the prospective employer to schedule my second interview for early next week. When do I tell him of this change? Should I tell them DURING the second interview, before or AFTER I've received an offer?
Update: I edited my original question, because I realized I was asking the wrong question for the answer I was seeking. I'm trying to determine whether it's even prudent at all to mention the fact that my current employer gave me a performance-based raise and whether I can leverage it in negotiations with my prospective employer, even though I'd already given a salary requirement during our initial pre-interview over the phone. Based on my raise, my new requirement would be $3,500 more.
