I am preparing how to walk through my resume for my upcoming MBB interviews. I have been asked to give a brief overview of my own resume many times before, but I am always wondering the best way to do this. Instead of going through everything by the chronological order, I usually get three most important bullets and make a theme to present myself while trying to limit my response under 40 seconds. I am also an experienced hire with several years of work experience, so I can't possibly go over every employer on my resume. The purpose of this exercise is for the interviewer to get to know you but also to see how concisely one can present a set of very familiar information. Any insights?
