Is the order of middleware calls predefined? Have you used it? 8. How do you use dependency injection? 9. How do you know if you are using a logger as dependency injection because the setup had an error or which specific service is used for logging? 10. Isn't it redundant to add ref to a function's parameter? 11. What makes you say that a function shouldn't be refactored to be ready for Unit testing? 12. What other communication protocols have you used besides REST and GraphQL? 13. Any difference between this in .NET and this in JavaScript? Second interview discussion with light live coding: -simplified version of the Polish notation that only consisted on paranthesis - write an algorithm that takes a string and returns a bool if the paranthesis are correctly open and closed Ex.
