legal – I sent codes and assets of my unity game as zip to potential employer, is there a risk of stealth?

I sent my indie game (just %10 completed) to a potential employer so they can look at my code, they didn’t want the whole code but I had little time so I shooted the whole game as a zip(My bad). Would they demand rights (wrongly!) in future that they own the game when I actually complete the game and release it?
