I've recently switched jobs around 1 month ago. I am now in a type of company I've never worked in before, in an industry I've never worked in before, but the money was a big step up for me and the role seemed to be a good fit by how they were describing it.
I went through ~ 5 video interviews, a HackerRank and Calliper test, and various other phone calls.
The problem is... I think they got the wrong guy for the role. I can't tell if I was just good at interviewing or they were just really bad at doing interviews, but the more I am in the role the more I realise that their expectations of what I can do are different than what they think I should be able to do. Mind that I didn't lie at all on my resume or during the interview process. I answered all their questions etc to the best of my knowledge.
The thing is, as of now (3 weeks and ~ 2 days), I didn't do much, just trying to read documentation, meeting people, etc. The company flew me out to their main HQ in the US (I live in Europe) for two weeks, all expenses covered, and I feel very uncomfortable knowing how much they spent on me in terms of money and time (the interview and background checks took 2 months).
Since I've been here in the HQ my boss and my boss' boss told me their vision for our department and how key a role I play in making everything happen. I told them that everything feels overwhelming, that it's going to take time, etc. They played it off saying I'll get the hang of it and that they don't expect a miracle by tomorrow.
Yet the more time passes the more I feel overwhelmed and out of my league. Before you say it, I don't think this is the impostor syndrome talking, I think their expectations when they hired me are different from what I can actually do.
I'm now waiting to finish these 2 weeks overseas before evaluating quitting, as it would be awkward to quit while in the US.
I'm just not sure how should I proceed and what kind of repercussions would I face. Like: could the company expect me to repay them back for the travel expenses if I quit immediately after or during my trip?
While I do live in Europe where employment laws are stricter when it comes to firing employees, I'd like for it to not come down to my employer deciding to fire me because he thinks I'm incompetent, so me resigning might be a better deal for the employer also...
