I applied online. The process took 3 weeks.

As you can read, the process can be long and difficult. I can write about only the logical/reasoning quiz step and the coding quiz step. They were both hard for me to do. I did well in the logical one; you just need to be focused and have enough time to take the tests. The coding was pretty difficult. I was not mentally prepared at the moment I took the test. It's not so hard; you just need to be focused and be prepared beforehand on what to use and what you need.

I cannot disclose the actual questions of the quiz, but on the coding part, be prepared to work with bit representation.
