Tesco interview questions

Prior to the one on one interview, a group task was set in which we were required to build a tower using paper, masking tape and pens that should stand for 60 seconds. People with clipboards watched and made notes while we worked. I am not sure what they were writing, but I must have impressed them, as I was told that I had the job before my one on one interview began.

Applied through recruitment agency. Phone screen with general resume based questions and some statistics questions. Then two interviews on-site, supposed to have 3, but I did not have the behavioural questions. Very nice atmosphere, a lot of questions on statistics, simple math, and an interesting case study to discuss. One needs to be familiar with basic data science ideas - machine learning algorithms for supervised and unsupervised learning, time series analysis.
