I was internally referred and heard back from a recruiter after 2 weeks. The initial HR phone interview was straight forward: talked about my education, explained my resume, experience using data, how have I used Excel. At the end of the phone call I was scheduled for an assessment day interview. The assessment day was 4.5 hours long. I had three 1:1 interviews and 1 panel interview with two other candidates. There was a case question on inventory that I had to work through with a group while the interviewers observed and asked questions. Overall the experience was intense but positive. The staff was friendly, helpful, and organized. I wasn't offered the position since there were many candidates with extensive retail backgrounds.
