Too many interviews - I had to talk to 5 people in individual sessions. Then for the assignment part (which is not paid), it's extensive and I could see one of the LT interviewers was barely paying attention or doing something else while I was presenting. You are encouraged to ask questions to other team members, but their ill will to answer was a problem. Then they came back with a generic response of "we decided to go with someone else" instead of giving valid feedback (and I know it was a lie because the role remained open).
