How many documents does an aircraft need?

Tell me about yourself. Why did you decide to become a pilot? How was your training, and what was the most challenging aspect of it? What are your strengths and weaknesses? What are your hobbies? What was the last plane you flew, and how do you handle crosswinds? What is the difference between the 800 and the MAX? Can you tell me about the anti-ice systems in the 737?
