the order of importance in terms of getting the interview

1) Ability for analyst at BB bank to vouch for you to get an interview. This entails networking.

2) School / work experience brand name. Work experience brand is probably more important for internship than for full-time recruiting, since for full-time you're either trading up (i.e. going from UBS to Goldman) or you didn't get an intern offer. Either way, the resume selectors aren't going to be that impressed with your work experience.

3) What you say on the bullets -- only when the BB can't come up with enough applicants via recommendations or brand-name experience applicants will they actually read the bullets and select you based on what you did.
