So it's the hardest application form I have ever seen. Just a tip: copy their questions, to notepad, try to answer them there, because they may close their application before you will be able to write your answers. When they open next time, you can just copy paste your answers. Each answer has a limit of 1000 characters, so make sure to fit to it. As they say in their application page you need to give complete and detailed answers covering everything what their questions asks, if you are just writing short answers, or forgetting about some parts of a question, your application will be refused.
