dunnhumby interview questions

A recruiter contacted me and we had a brief phonecall. I sent them on my CV and I then had an interview the following week with the Head of Media and one other. I then was invited to a second round where I had to present a case study. In the end I was told I didn't have Marketing experience, despite the job spec not listing Marketing experience.

The whole process was professional managed by the HR team. It was a day- walk-in process for various analytical profiles. All rounds are elimination round. Round 1- R/ Python Test Round 2- Post clearing test, is a introduction, current education, past experience and technical round either with one interviewer/ a panel of 2-3 interviewers. Round 3- Post second round, One more technical round with some cases (to check your approach) Round 4- HR round
