Got an email from this so called company. tried searching online about company so i can be prepared for interview. No website, first Red flag. No Digital presence.
But thanks God these reviews saved me. In reviews it was mentioned that they charge 200 Dirhams. Gave them a call to confirm. They said you please come than we discuss what is the job and how much salary. I asked is there any registeration fee the lady said its 200 Dirhams. I hung up the phone.
How are they even doing business in UAE?
