I have learned a couple things that I am happy to share with other job searchers:
1. Balancing an interview "pipeline" with companies you're waiting to hear back from is tricky to say the least.
2. Don't assume that you'll be juggling multiple offers and will have to turn away one of the companies nicely. Get over that assumption, pick your ego off the floor and move on.
3. You know you aren't that psyched about a job when the thought of interviewing with them seems like the most annoying chore on your to-do list, and you wish the hiring manager would just pick up the phone and tell you that they are canceling your interview because the position has been filled.
4. People expect a lot more from MBA candidates than they do from undergrads and pre-MBA job switchers.
5. Have questions for your interviewers. Good smart questions. Write them down in the notebook you're bringing to the interview so that you don't go blank.
6. Having a put option on yourself (i.e., an offer to return to your old company) can make you really jaded/lazy.
7. Remember when I said not to pursue crap you're only marginally interested in? That was good advice.
8. Stay hydrated.
I'm off to the GSB show, which should be highly entertaining. Have good weekends!
