I used to work as a junior developer for more than half a year at a company which ended up firing me. The reasons are irrelevant but no conflict occurred - at least as far as I can judge, it was handled professionally.
In my town, there are only few possibilities, and fewer are the ones I can find online. One of these involves a company also looking for junior developers, and my town being somewhat small, the location is the same office building, just one floor below my previous employer.
Maybe it's my fault, but I can't help myself: I feel uneasy because of it. I know have very strong reasons to accept the first incoming possible job offer, but in the same time, it's just awkward to imagine meeting my ex-colleagues.
From an outside view, are my concerns valid, or it's just paranoia?
