Whatever you do, do not join a startup, unless you really, really know what you want to do and the startup has work in that area and you get a sense they'd have really good mentors in the company. The reason I'm saying this is that, if you are only going to be around until January, that's not long enough to upskill on anything meaningful. Sure, you could get some good keywords on your resume, and if that's what you want, that's fine. But if your goal is to improve in a meaningful way, that's not going to cut it, unless the startup is truly exceptional with amazing people. Most startups aren't like that.
