The interview starts with a phone screen from a recruiter. It consists of a few basic multiple-choice questions that any mid-level software developer should be able to answer easily.

The next interview is online with a shared coder pad. The interviewer will be an engineer, and they will give you about an hour to code a solution to an algorithm question. Be prepared to give optimization suggestions and runtime analysis.

If you make it to the final round, you will be invited to go onsite. The onsite interview consists of 4-5 separate interviews and lunch.

The technical questions are difficult. Be prepared with experience answering questions on a whiteboard. Master all of the data structures and algorithms concepts.

Given an nxn matrix of numbers 1-4 (drawn on the board), write an algorithm that will return the identifying number of the largest cluster in the matrix and the number of items in that cluster.
