You will be required to do an small coding assignment if they reply to your application.
Then, on interview day, you will be webcamming with three of their staff members.
You will have to make some additional modifications on the spot to your technical assignment. You will have your code editor under their examination.
Good luck. It was not made clear how this assignment is transferable to what they are doing in production and will override your qualified work history if you cannot code under time pressure to the minute.
