I believe they are using the Sheraton Hotel name to post jobs in the indeed site (in Brazil). I sent my resume and they sent me an Interview Form with the Sheraton Park Lane London logo. And in the form they asked me If I would pay to acquire a U.K. work permit visa. But since I thought the position was for Brazil (as stated in the job post), I said I was not intereseted. But then I got suspiscious and started to look in the internet and got this scam alert.
The e-mail was: Kieran Quinn [sheratonrecruitmentworldwide@consultant.com]. I hope others don't get fooled by this false post.
