Another hypothetical scenario that could be taken into consideration is the following: Before hiring you they had either interviewed another candidate that matched their needs and was more experienced than you, or expected a friend of theirs to join their team, but did not reply back for a while and due to their tight schedule, they had to hire someone urgently, thus leading to your hiring. After hiring you, between the end of second and third week, this aforementioned candidate or friend replied and said "I'm available now" and decided to let you go; the only thing that had to do is to figure out a way to use as an excuse to fire you. I have been there myself and I know first hand how it feels; therefore I will repeat myself: discuss the matter with a lawyer and feel happy that you dodged a bazooka, not just a bullet!
