I applied online. The process took 1 week. I interviewed at Tesco (Northampton, England) in May 2016
Interview
When you arrive, you will meet your selection board (usually two or three people, including the supervisor of the position and a representative of Human Resources). The team leader will tell you what to expect, and will explain that the board will be recording your answers for later review. Don't let this recording process distract you—it’s a normal part of the interview and necessary to make a complete assessment later on.
Interview was around 2.5 hours in total. Started with a group interview then 20 minutes on the shop floor shadowing a checkout colleague then finally a 1 to 1 interview with a manager.
Very easy, just asked a few questions about my experience and my availability on time etc. what days i can work and my flexability on the dates i can do
Nice environment. Kind people. Asked the right questions and I felt I could ask any questions i had. Overall I enjoyed the experience and would recommend to other people to do an interview with them.
