They asked standard data structure questions. For example, search times and design decisions.
Write code to find the next least node in a binary search tree given a node.
The second round of interview I was asked to calculate the product of three highest numbers in an array. The interviewer kept further questioning me about giving a more generalized answer.
Basic coding and algorithms.
Good coding question
There are a lot of questions that can be solved by arrays, sorting can be done in O(nlogn)... but they are looking for more than just correct answers, having an answer with a high time / space complexity won't help you. There was a tough question about linked lists with next and arbitrary pointers.
What's the difference between the stack and heap when they are initialized.
The technical problem wasn't something very difficult at first sight, but the trick was finding out the most efficient solution, which involved using tries. This solution was not implementable in 45 minutes, so the interviewer asked me to implement a specific part from the solution. There were very few behavioural questions, and nothing unexpected.
