Do not trust your gut. You're new to the industry and full of insecurities, doubt, impostor syndrome etc. Many people are. Your gut is telling you all sorts of things that are completely false. Do not trust your gut.
Now, WRT trusting your gut... You aren't in a position to know for sure how things will turn out with this company, and you won't know for sure until someone tells you ;) You deserve to be in a place where you feel secure.
