I just graduated with my BS in physics and applied math this December 2009. I'm currently taking 2 mechanical engineering classes right now through my school's extension program for BA/BS degree holders. After taking these ME classes for 3 weeks now, I'm certain that I want to enter ME for my career. I know I want to eventually go for a MS in ME. But I'm debating whether to seek employment right now, even if it means dropping those classes in the middle of the semester, or to just take the classes. The problem is that I wish the most to work on tanks, weapons, and missiles for a defense contractor, but I'm not getting any job offers from them. I have gotten a few interviews for other technical positions, such as computer programming/math for economics/finance and website-design companies, but none of them sounded very interesting. If I get future offers for these positions, should I take them, so that I could put them on my resume as work experience so that I can eventually obtain an engineering position? Or should I just wait until I get an offer for a position related to engineering at a defense contractor, not just because the work is more interesting, but because they can also reimburse me to work on a MS part-time? Another dilemma that I'm having is that I applied to the government labs, such as Sandia, for the SULI summer program. When I applied, I wasn't sure I wanted a phD or MS. But now after thinking it through, I'm sure I want a MS. If I get offered a position at one of those labs, should I take the offer? Sorry my situation sounds so complicated, but I'd really appreciate it if any one could help, probably physics BS -> engineering MS people could help the most.
