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.
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
