Google

It's long and hard, lasting about two months. It contains two rounds, with the second including three interviews. I have to say some interviewers are friendly, but some are not good. I'm looking for another opportunity.

4 rounds Data structure and algorithms: * Depth First Search * Breadth First Search * Arrays and Linked lists * Recursion * JSON patching * Heaps * HashSets * HashMaps * Lists

First round - phone call - asked about technical projects, current org work, coding experience, and preferred language. Second round - coding interview. Two questions - a graph and a BST question.
