Mars Manager interview questions

The interview process is really long it took about a couple of months. There was very vague feedback and responses were slow. Two interviews and the second one was to present a Case Study

Initial phone screening and then second interview included two Mars representatives (hiring manager and counterpart). Interview was extremely cold and unfriendly. Understand that virtual interviews can be tough to gauge emotion and tone but I immediately knew in the first 5 minutes that the hiring manager wasn't the type of person I would enjoy reporting into. Not a culture fit. It then took over 3 weeks for Mars to notify me that I wasn't selected. I think this is an area they need to improve on given the competitive job market right now - it's crucial to update all candidates in a timely manner. It's only considerate and respectful.
