Marakon interview questions

The first round includes two in-person interviews, very standard fit/behaviour questions for warm-up, followed by a case study. Cases are okay; one of them is a written case. The written case interviewer was friendly and engaged, while the other was 20 minutes late and seemed quite lethargic throughout the interview. They sent a travel reimbursement form for me to fill in, but I never received my travel costs, lol. Also, no feedback (even though they make it clear before the interview).
