try to answer the questions first, group interviews you are only asked 2 which is good. examples from anything in your life not just work related stuff which helps. be friendly and engaging, usually everyone is a bit nervous and quiet at first but people tend to relax once things get started. tesco also like to to be flexible with your work hours- they told us that it is often the people with the best availability that get the jobs, so try to put down as many hours you can realistically do but bare in mind that if you get the job you may be asked to work in these hours so if you really cannot do nights or 6am starts don't put that down. also with the sop floor exercise, if there are customers around you try to engage with them, for mine it was a little tricky to do so as i didn't actually see any customers where we were working! also if the managers are around when doing the shop floor exercise ask them questions tell about your interests, just make conversation and appear helpful and friendly
