I got the interview through a recruiter who contacted me on LinkedIn.

My first interview was a 1-hour Skype call. The first 20 minutes involved general questions about my CV, followed by 40 minutes for three coding exercises.

After this, I had an on-site interview. This consisted of three separate interviews, each lasting almost an hour, conducted in the interviewers' offices. All of these focused on programming on a whiteboard and were very different from each other.

At the beginning, the usual ones:

• Given a string, shuffle it so that no two same letters are together.
• Sorting with low memory and its space/time complexity.
• Given a random list of integers, write a function that returns sets taken from the list such that the sum of these numbers is equal (if possible).

A lot of abstract questions about the fundamentals (sorting, etc.) and some very tricky ones about how to design efficient algorithms to enumerate some special type of linked lists.
