There was one question with 3 colors of balls in an array. You needed to sort the balls so that they would appear in the same group within the array, with a complexity of O(n).

There were three interviewers, each asking me one algorithm question. The first was in Python, the second in C, and the third in Python. It was pretty nice, and they are generally looking for your thinking process.

This was a straightforward and honest interview. It's the best place to work. Thanks for the opportunity. They were professional, courteous, and on time. I didn't have to wait, and communication was very good. The application process was easy.
