Should I get a master's degree or a full-time job?
However an MBA is a different story. Getting an MBA at a good school can be extremely expensive and only you can decide if the opportunity cost is worth it. I have several friends who wanted to switch careers after spending a few years in technology and used an MBA to make that leap. But even they will tell you today that you don't need to spend 2 years and $150K to make that happen.
Hope that helps.
Today I'm a software engineer at a company that requires MS degrees for all their developers and it's a good environment - although I'm still looking for a place where I can leverage both my master's degrees.
In short, I'm happy I chose a job. Granted, I was lucky to get one that is doing work I consider meaningful. But having that job has made it much more clear to me what I'd like to do in the future. The MS I'd apply to now is dramatically different than the one I'd have applied to before having the experience. Which is a good thing I think.
If you can't get a job upon graduation, then go to grad school. But know that graduate degrees (in computer-related fields) offer a poor ROI. You should probably only pursue one if there is specific research that really interests you and you don't mind being in debt for a while.
