  • •Never pay any amount of money — for a file, a training, a uniform, or an interview. A real employer never asks the candidate to pay.
  • •Never send a photo of your ID card, passport, or banking details before you have physically verified the employer exists.
  • •Always meet in a public place, during the day — never an isolated address, a private home, or a location you cannot verify in advance.
  • •Tell a relative or friend exactly where you are going, with whom, and at what time — and share your live location if possible.
  • •Search the company name online before going: a real business has a trace (website, reviews, other employees, an official address).
  • •A salary that is far above the market rate for the position and the city is a red flag — be extra cautious.
