I didn't feel it at all. In fact, I can personally vouch that all of the big banks are happy to include older candidates on their closed interview lists. I can't think of a single bank that had any reservations about inviting older candidates to private events. I'll also say that of all the career-switchers interested in banking here this year, the two people that had the most success were me and a younger guy with a few years of experience in consulting. Naturally, people with prior banking experience had the advantage in many cases, but age was a non-factor as far as I could tell. I'd say that networking and schmoozing skills are 1000% more important than age. So I didn't observe age as a factor throughout the recruiting process, and once you get into the interview room, it's up to the individual to win the job offer.
