Online assessment: 5 problems - 2 leetcode hards, 1 relatively easy SQL query, 1 refactor-a-class problem and 1 design problem Technical interview: How do you create a bean? No, I don't mean that. How do you create the bean? What type of bean is it? That's not what scope means (it actually is). Ok, and how does Spring do that in the back? Tell me the implementation.
