I live in Saudi Arabia. I applied online for a job at a company in the UK through an agency. The agency sent me back an online job interview application that I have to fill in and sent back to them. After a couple of weeks the agency sent me a job offer to be signed from my side, and it asked me to contact a travel agent working with them so that they can furnish me with details on how to get the named document and help in the procurement of my UK Visa and other travel documents that will be needed from me to proceed to the UK.
The agency did not ask me for my certificates, and did not conduct an online interview through telephone or Skype.
Should I worry? Should I ask them to conduct an interview?
