BIOTRONIK Sales Operations Associate interview questions

One 1.5hr interview with 3 people from the managing team. Brought in for a second 2.5hr interview with the same 3 people as well as hr and the person in the current position. Pretty standard interview - no reason to take 4 hours total to ask the same questions. Did not receive offer or even a follow up with a denial. Overall a waste of time and no respect for the interviewers time.
