Was he unreliable as a person before? Was he combative with his previous employer and colleagues? Was he actually in prison all this time? What if this guy is a corporate spy?
I’m not sure you will get that information by asking about a gap.
I believe it would be more acceptable to ask questions more specific to your concerns. “Can you tell me why you left x position?” Even then, you are not going to get the information you are so suspicious about, you will get a bullshit interview answer.
I don’t keep them in the fridge, I’ve got my own hens and I didn’t before when I got shop bought eggs. I have 0 concern about salmonella or anything like that.
The fridge egg holder is for keeping hard boiled eggs, not raw ones.
