I interviewed with a firm I really liked two months ago. I wasn't confident in the interview as I felt I was being "drilled" by one of the attorneys. Since I also speak another language, I was tested on my language skills, and forgot the word for "ladder".
Needless to say, I sent a thank you letter within the next two days, and received a response from one of the attorneys about the pleasure of meeting me, and that they'd inform me of a decision in the future. Naturally, after not hearing back after a couple weeks, I moved on and applied/interviewed elsewhere. (I also thought I saw a blind ad from possibly the same place reposted on a job site.)
Earlier today, I received a phone call for a second interview later on this week. I was surprised at first, but also relieved for getting another chance, even if it seemed like a long time. I guess there's no timetable for second interviews?
