The first step of the process was a HireVue recorded interview and a set of puzzle games.

The interview consisted of 5 behavioral questions for which I needed to record video answers. The questions were common behavioral interview questions (e.g., "Tell me about a time that you had to learn something quickly," "Can you tell me about a difficult situation and how you overcame it?", "What is your greatest accomplishment?").

The puzzle games were a quasi-intelligence test that assessed the ability to do arithmetic, match patterns, and other basic cognitive activities. If you do fine with games on the app JobFlare, then you should do fine here.

The second step of the process, about a week later, was a coding test from HireVue. I had to solve two coding questions in a programming language of my choice, with 30 minutes given for each. These were very simple questions that seemed to be aimed at testing basic programming competence. I wouldn’t even call them LeetCode Easy.

The third step of the process, about a month later, was a phone interview with an IT manager at the company. I was only asked a few simple questions like "What makes you want to work here?" and "Which city would you prefer to work in?". The rest of the interview was the manager giving information about the position.

The last step of the process, a week later, was two one-hour Skype interviews, each with a different senior IT person. They mainly asked ordinary behavioral questions like "Tell me about a time you worked with a difficult person." I was also asked about the projects on my resume and one technical question ("What is a REST API?"). There were no coding questions.
