The interview process was standard one. There were three stages. The first stage is the screening interview where they wanted to hear a little about me, and where I had to describe a project I did in the past. Why I chose certain methods and such.
The second interview was the take-home task where I had to design a solution. And then in the third interview we discussed my solution, how I did X, why I did and such. They are interested in learning about your process of designing a solution.
