dealz; did this information that he quit come from him? or other sources that were not from his conversations.
I suspect the guy wasn’t trying to mislead you, though I doubt any guy would feel comfortable going on a first date announcing hey btw I am unemployed. Especially if he wasn’t sure it’s nogeah meeting you for the first time. Especially these days.
If after showing an interest and requesting a second date he continues to mislead you on the second date, then I feel you should ask him if he’s currently working there. If he lies point blank, then he is lacking integrity and you should act accordingly.
