Good interview , fast progress and process, seems nice but have so many questions as far as job security and pay ,longevity and work shifts … interested candidate but need answers on this matter

It was a great interview about ten minutes then i did the assessment that evening and had the longer interview the next day with being offered the position.. was told there is three day onboarding then a month of training…after reviewing reviews im concerned about taking this position..they need weeknights filled 6-3 or 10 to 5..and u choose which two off days u have ..can’t be the weekend
