I went to the SF one, presented by Akiba Smith-Francis of
MBA Mission. Same turnout - about 25 people. The presentation was pretty straightforward - mostly what I think is common sense for interviewing for jobs. If you're a recent
MGMAT student, you'll be able to find the presentation online.
They touched on a few things that might be more applicable to certain schools. For example, applicant-initiated vs. school-initiated interview. Basically, some schools (like Tuck) allow applicants to sign up for interviews before they submit their app. It's basically a blind interview. After you submit, it's invite only. I'm applying to mostly Euro schools, so I don't think it's something I can take advantage of, but wanted to share it with the rest of gmatclub. If you can sign up for a slot while they're still open, the consensus is that it's in your favor. (As opposed to waiting for the school to invite you.)
Akiba also went over knowing your story, preparing a few extra stories, and telling your story in reverse chronological order. That was interesting to me. Every time I've interviewed for a job (and working at a few startups that didn't take, I've interviewed for plenty of jobs) I've always started from oldest experience first and worked my way to the most current. Her reason is that with limited time, better start with your more recent experiences. Food for thought...
Another minor note - dress appropriately for the interview. Meaning, if it's at Starbucks on Sunday, don't wear a suit. If it's in a more formal setting, vice versa.
Good luck to all!
