I applied online. The process took 1+ week. I interviewed at Tesco (Belfast, Northern Ireland) in Mar 2016
Interview
The interview was very brief with not much pressure. Very easy to answer some questions with some caveats within the interview. Also gave you a glass of water to make it less formal than you would have first thought
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.
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.
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
