I've reported these guys to the UK CAA Whistle-blower line. They are looking into this Airline and will get back to me sometime next week. I checked the registered domain address on whoisinfo. I turns out that the domain is registered in Amman, Jordan. They haven't bothered assigning a name to it either. The English in some places i.e on the contractual agreement is poor. I had a friend who at present lives in Dubai to drive over the Ras Al Khaimah airport, the airport duty manager has never heard of the Airline/Company ever before. The website seems to suggest that they are a recruitment consultancy firm, which is fine, although they don't have any affiliations with other airlines.
I think by doing what they are doing they aren't breaking any laws as such. You're simply paying 3800AED-5000AED for a Assessment day of which they pocket 60% with no Job at the end which contractually they aren't obliged to offer you.
Stay Away Guys!
