I) Interview with a recruiter. Talk about yourself (skills, past projects, etc.).

II) Exercise: Write a simple application about the stock market. Pay attention to the implementation of the exercise because they want to see what you know about OOP. Therefore, I suggest you use:

• Hierarchy
• Composition
• Interfaces and Abstract classes
• Integration Test

Bad Stuff (Don't do it!!):

• Large use of static methods
• Use of complex conditional statements
• Use of long, complex methods
• Implementations of unuseful test cases (e.g., read/write on file)
• Avoid logs (IF NOT REQUIRED).

III) Technical Interview

1. OOP: What is it and which are its pillars?

2. Lists and Collections in Java: Definition and complexity of operations.

3. HashMap in Java: Definition and complexity of operations.

4. Why JP Morgan?
