To the Management I received a job offer and they want me to scan my documents.. Was it your management or not?

you don't know and think they are going to answer you on Google.

If you're receiving an email that doesn't have @ritzcarlton.com, it's probably a scam. I don't work there but it's a 5 star luxury hotel and luxury hotels can probably afford their own domain name.

Was it the hotel or its a scam?Decent and clear answer please?

The best

Not sure about this question......
