I had no clue there are laws dictating that you can't ask how an employee was at a pervious job. Seems like a terrible idea to me. Is this a state by state basis?Where there are laws governing what can be asked and said. And yes people try to
get around these laws and try to use other ways, but a lot of companies have policies preventing employees from saying too much due to the ability to get sued. They'd just rather not deal with that shit.
In general mostnew employers just call to confirm you actually worked where you said you did. However listing someone as a referral is a different story.
Frankly you are under no obligation to give a two weeks notice or pretty much any notice. Its a bullshit made up thing, and any company not willing to hire someone because they didn't give notice at their previous position is kneecapping themselves.
Hell a lot of people land new jobs before even leaving yheir previous so notice is pointless
