De Vere Grand Hotel Brighton — Inquiry about job opening

Few weeks ago I got an email from
De vere Grand Hotel regarding job opening and recruiting. I send my CV in reply.

Then in second mail, they ask me to fill interview form and reply with copy of passport. I followed steps and done process.

In Third mail, I informed that I am selected and I need submit my documents with scanned copy of attached form.

This process is going smoothly from beginning. So I doubted it and start searching on internet about this entire thing. And I found many other people complaining on same topic and had same procedure as I had.

I am still doubting this entire thing and found same thing here too. So, can you please about this recruitment?
