Ballpark figures on your salary are dependent upon the company, your background, your skills, your achievements at school, your internship between your first and second year, the market conditions at the time you are looking for the job, your interviewing ability, .... Get the idea?If you want to trudge through your job and MBA, go for the part-time route, but you'll have absolutely no life outside of work and school for 3+ years. Then, you'll be tied to your company for another 3 years or so. If they are only paying half, though, I don't see why you would have to commit so much to them. If they paid all up front, or via reimbursement, then it's par for the course.Go full-time and take the risk of no income and footing the bill for a couple years. You'll enjoy the experience 10x more and probably have a better chance making the career transition you're looking for.
