Third Bridge Associate interview questions

The initial phone screen lasted about 15 minutes and was pretty standard—they asked about my experience and told me about the position. The interview—a phone interview—was a behavioral interview that lasted about a half hour. Perhaps it was due to my inexperience with behavioral interviews, but I found it quite tough. I can't remember the exact questions very well now but they were all in the format of "tell me about a time when you..." (helped a teammate who was struggling, had a difficult client, etc.). I had prepared answers for most of them and delivered them, but after every one, the interviewer would ask for more specifics. One of my stories was from over a year ago so I didn't have an answer to his question because I couldn't remember a detail.
