I applied through university. The process took 2 weeks. I interviewed at dunnhumby in Oct 2011
Interview
Contacted company through university career services office. Went to two "pre" nights which consisted of a meeting at a bar and another presentation and receipt activity where we were put in groups and given different receipts and had to draw certain conclusion/ analyze different trends in the receipts. Never really felt like our answers were right, only half right. Interview followed up 3 weeks later and was two people from recruiting who asked a lot of behavioral questions. Used confusing language to try and lead me to an answer they already had in their minds. Once again my ideas weren't right, only half right. Good practice though. Be prepared totalk about previous experiences.
Interview questions [1]
Question 1
How would you decide what quality of clothes to have at different stores
I applied online. I interviewed at dunnhumby (Oslo) in Jan 2026
Interview
The interview process consisted of four stages: phone screening, Teams interview, case interview, and a final interview with the manager.
Overall, the process felt unnecessarily long for a role that pays well below the industry average. I was also required to travel for the two final stages, but they did not cover my flight expenses.
I was rejected, and the same position was posted again the day after I received the rejection email.
While the interviewers were professional, the time and cost involved made the process disappointing. I would think twice before applying.
Hr email me first, and schedule a date for phone interview. They asked about my salary expectation. Maybe it was out of their budget, anyway there were no follow up next
Long interview process, even did an entire presentation based on fake data provided. After three rounds of interviews and putting together an entire presentation I never heard back. Very unprofessional, especially since they said I was one of three people still in the process.
