HARMAN Developer interview questions

Reverse a linked list as well as optimise it along the way. Next was a topological sorting question, basically had to tell if there is a cycle in the graph . The edges were given in an array and there was no time constraints

The interviewers were friendly and asked relevant questions through out the interview. I feel my answers were good enough even though I did not try too hard. ALthough, interwiewer kept changing dates after confirmation so that kinda messed with my scheduled a little.
