I've started working at a technology startup remotely as a programmer. The startup is small, around 10 people (including all the higher hierarchy). I've been approached and hired mainly by the CTO of the company. The initial Skype calls looked positive, but once I've agreed to work for them I haven't heard back from anyone except the actual team lead that I work with. So no "is everything fine", "we're happy with your work so far" or any of the like. The only few times that I've been contacted back was regarding payment info and again no "So how are things going, is everything ok?" type of questions, just a plain "Let me know your payment info, bye.". And I'm not even talking about performance feedback which seems non-existent - even the lead never says anything regarding my work - just here's a task, thanks, bye.
I've been working for 3 months so far and they're planning to move me to an on-site position, but I'm starting to have doubts and thinking about cancelling the deal. The cold communication approach of the higher hierarchy is sending a really bad signal. Am I being paranoid?
