hotel job interview

Went for a job interview in the hotel, everything seemed legit he had my Resume and everything, they said they would give me a shot after it and asked me to provide my social security number and ID, they took photocopy of my id and I wrote my SSN on it and they said they need it for background checks and will inform me on drugs test soon, baring in mind I have no job offer yet but applied through official website and person had his card,name tag and everything in the hotel
