The process involved an online test, followed by a virtual onsite interview.

One LeetCode Medium question was presented.

Rather than the actual code, they were mostly interested in how I approached the problem, and I had to speak aloud about my thought process in solving it.

Number of Islands

Level Order (and Zigzag) Tree Traversal

Word Series (Word Ladder 1 & 2, Word Break 1 & 2, Word Search 1 & 2)

"parking lot" OOD question

Remove all duplicate numbers from a list. Given a huge database of sentences, write a class to find the most frequently used words.

Questions on data structures like ArrayList, LinkedList, HashTable, Binary Search Tree. Discuss the differences between these data structures and when you would use each one. Discuss Inheritance and Composition.

First round: 2-3 behavioral questions followed by a coding question. The question was: given a binary tree, find a subtree within the binary tree that adds up to a certain target sum.

Second round: 2-3 behavioral questions followed by an OOD question. The question was a bit vague, and I had a hard time understanding their English, but essentially it was to design a warehouse class with certain constraints such that the particular warehouse could only store certain products.
