I offer two sides to my answer...
1. Considering the heap of debt that I (and most others) am in due to this whole process, I have to agree with the above posters who say TAKE THE JOB!!!! If you can get all your present bills paid off and actually have tuition money left over, you'll be doing bit better than the rest of us!!
2. THINK about what that (pharmacutical) job will entail and whether you will have enough time to full-fill you job related duties AND deal with the admissions process (the MCAT is just the BEGINNING!!) The reason I say this is because my good friend, study-mate, and fellow applicant recently accepted a position with a well-known pharmacutical company. She went through a month of intense on-sight and off-sight (had to travel) training and is finally "learning" her routes. She spends 50-60 hours a week doing her routes and then several hours a night doing follow-up paperwork. Of course, she's being paid well, but ended-up failing to return two different secondaries because she just didn't have time to finish them before deadlines. Naturally, this has severely limited her chances of getting in this year (she only applied to 4 schools) and even if she does get an interview, she doesn't know HOW she's going to be able to get time off to go to them. In addition, if she doesn't make it in, she won't have time to study for the April MCAT and probably have a hard time preparing to apply next year. There's also the issue with the pharm company hiring you in the first place...you don't want to tell them that you're planning to go to med-school in the fall, because those companies don't want to waste their money training you if you're just going to be gone in a year...and that is where the problem begins. You take the job, you're too busy to concentrate on applications, and even if you get an interview, you're going to have a hard time finding an "excuse" to go (without losing your job).
Unfortunately, this is the reason I'm working for a "temp" agency right now. I haven't obligated myself to any one employer and I have the freedom to take off from work when I need to. The pay's not great but it's the only thing I could find that would allow me the time off without the threat of unemployment.
Good luck!
