Q1: Matching brackets problem, used stacks to solve in under 10 minutes. Gave detailed explanation because I was pretty familiar with the solution. PS: Interviewer asked some data structure problem during this one, forgot the question but it was something about which data structure is best for removing and adding items? (linked list)

Q2: Candy crush 1-D problem, thought it'd be easy but it was actually tricky. Spent 20+ minutes on my naive solution but wasn't able to finish. After the interviewer gave lots of hints etc. was able to finish 99% of it.
