onsite interview 1. with two VP. They are very friendly and will give you some hint if you're able to catch it. sadly i was nervous and missed out the hint during discussion. the question is about currency conversion. i wasn't able to think of a proper data structure to solve it at first. my solution was to build graph and find a path in the fastest way. they said i was on the right track. but i didn't finish it. i should have used bfs, but i used dfs and didn't complete the algorithm. so i guess there will be no 3rd interview. 2, with a PM and associate. 1st question is simple and it's find common elements in two arrays and optimize your solution. 2nd question is to find a sub array that has the largest sum. i solved this problem by brute force and wasn't able to optimize it. then the associate asked me some system design questions and network questions, which i didn't answer well because i have limited knowledge in network.

In a list of songs, the i-th song has a duration of time[i] seconds. Return the number of pairs of songs for which their total duration in seconds is divisible by 60. Formally, we want the number of indices i < j with (time[i] + time[j]) % 60 == 0
