Don't worry, it's not robbing you of the the evenings and weekends, which "maybe you like", it's a fun new challenging opportunity. Have you had a chance to panic yet on Saturday morning at 3 AM? Would you like to? It's such a thrill.
(edit: and by "hackathon" because I realize there's a bit of room for ambiguity, I mean internal corporate Hackathons where the company "allows" dev teams to take a "break" from "regular" work in order to ideate and build new features and functionality that--if their idea gets chosen--becomes "regular" work in and of itself. It's those kinds of hackathons I've started removing myself from)
