The process begins with a phone interview: pretty basic name/date of birth/employment history questions. He/she then asks about a time when you went "the extra mile for a customer," or something along those lines. This interview lasts for about five minutes or so. It's pretty straightforward.
The tougher cookie is the group interview. My group was a bit large, 14 people or so, directed by one interviewer, who was refreshingly pleasant and made everyone feel at ease. You're asked to fill out a form, which consists mostly on your current availability, nothing complicated or too long. You hand that in along with one copy of your resume. Then you're given a project; you team up with a partner and then you introduce your partner to the group and give a little background information on him or her. The only people who seem remotely interested in what you're saying are the other applicants; The interviewer hardly looks up from her paper, asks one question at most, and reacts indifferently to the answers. Understand that the interviewer doesn't care about what you have to say about your partner, but about how you "sell" your partner. This presentation lasts about twenty minutes depending on the size of the group.
The video that's played after that is ten minutes long, cookie-cutter "Wells Fargo is the happiest place on earth" kind of video, but make sure you pay attention, because you're going to get asked questions on it.
The next thing is a series of questions that are directed to whoever wants to answer, and it's the longest part of the interview. Obviously, this is your chance to participate and sell yourself, so be outgoing and memorable. In fact, the entire interview is all about you being proactive and memorable, so ask lots of questions, show your interviewer that you're genuinely interested. Remember, they don't have to hire somebody from every group, so you're not just competing for that position with the people in that room with you, but with hundreds of other applicants so, look the part, be participative and leave a lasting first impression. You may think you have extensive experience, but if the interviewer doesn't remember you, you're probably not going to book that job.
Two hours later you're set free, and this is when you practice SHINE. It's basically eye contact, smile and a good handshake. Call your interviewer by name, express how appreciative you are for the opportunity, and please feel free to over-do it.
After the group interview, be prepared to wait a while for a 1-1 interview, or a rejection e-mail for that matter. You're supposed to receive a follow-up from them during the upcoming week, but unfortunately, that is not always the case. I waited about twelve days before a branch manager contacted me by phone.
