I applied through an employee referral. The process took 1+ week. I interviewed at Co-op (Shrewsbury, England) in Aug 2015
Interview
I handed in my application form and was offered a phone interview a week later. I was contacted and was asked a few basic questions on how the company was run and what I would do in different retail scenarios. I passed this test and was invited to a face to face interview a few days later. We discussed my availability and I was offered the job. Quick and easy procedure.
