It was a nice experience. There were 2 back to back phone interviews. The questions were mostly related to Linked List, Binary Tree, algorithms and their complexities. One question was about difference between Stack and Linked List followed by their complexities. Also there were two programming questions.

system design and leetcode style question. It told me to design a system and walk through how everybody would be using it, what kinds of implementation it would need. As for the leetcode it combined a lot of leetcode problems together into one for an product recommendation system.
