Mars Product Manager interview questions

telephone call with HR that covered a lot of what the role entailed and what the company was like to work for. some great benefits offered, looks like a great company to work for

Interview process took several hours and the use of a panel interview made it incredibly stressful for me, particularly considering many of the questions were duplicated. The panel interview definitely needs to be shortened; a 2 hour interview in the working day is not very reasonable to expect of possible candidates. Process was as follows: 1) Screening call with talent agent 2) 1-hour interview with hiring manager 3) 2-hour panel interview with 4 peers + project management presentation
