Very easy, just tell the boss you have hands and legs then they will hire you and request you to work the day after. I refused the offer because it makes me feel uncomfortable

The whole process is very quick, I applied the job, then they call me the day after I applied, and have interview in next few days, confirm offer to me immediately, and request me to work as quick as I can. It is wired and strange....and the interviewer is harsh and demanding, seems not good company. I rejected the offer.
