STEM is huge, which major did u graduated on?....
I would suggest.....If you do not have any computer background ( means..if you didn't took any programming class in school like C, C++...) go for QA/BA... its easy to learn but hard to find job.
If you have little programming knowledge or interest, take risk and go for Java or .Net. There is quite a lot learning curve but its worth it in the long run.
