The Interview process is ridiculous. There are 50 questions that you need to anwer in 15 minutes. Many of those questions require calculous and/or abstract analysis that takes up quite some time. I would say 50% of the questions are irrelevant to the role. I understood that it does not matter how good you were at the test, if they are already filled with the required position, they will just fail you. Very unprofessional.
