I'm currently studying my M.Sc. in computer science and will be done with it in a bit more than two months. I got a job offer from a big and well-known company, but the position is not really related to things I'd like to do, and I don't even have a good understanding of what I would need to do there. My potential boss is aware of this, but he liked my performance during the interviews and he believes I'll learn and be a good fit in their team.
I don't have any other offers, because I applied to a small number of companies, got rejected by most of them and still waiting for a reply from one company where I got to the final round.
I'm afraid I won't find anything better, and I don't want to end up being unemployed after finishing university. So I'm inclined to accept the offer. However, I'm not sure if this experience would help me to find a job later in the area where I want to work. I also don't want to just work there for a few months until I find another job, because that's a bit unprofessional.
I can't decide what to do: Should I accept this offer and hope that I'll either like the job or will at least gain some experience? Or should I keep searching for something in my area, although there is not a lot of time left?
