Is anyone else noticing a big disconnect between what’s said in an interview and a contract?

Is anyone else noticing a big disconnect between what’s said in an interview and a contract? I noticed recently that companies are not being transparent about job requirements in the interview but including additional duties in the contract. Seems like a waste of time for both parties. A company was looking for freelance help with a project but sent a contract wanting me available every weekend but couldn’t promise any set hours of work. This seems like an on- call position without wanting to pay for it. They also wanted me available for same day turnaround for projects but didn’t want to pay a rush fee. Not my idea of being transparent. No thanks!
