Contacted by a dunnhumby Recruiter, and a first interview was scheduled with a Senior Shopper Insights Manager (experience based questions only). Following this, a second interview was scheduled with the Hiring Manager and Senior Shopper Insights Manager (case study and presentation - you have 1 hr before the interview to review the case study and prepare your presentation - followed by competency questions ). Both interviewers were approachable and friendly. Never heard back, so presumed it was a rejection.
