Altimetrik Interview Question

The basic stuff from programming • OOP questions | What is polymorphism, inheritance. • What's is overloading and overwriting (even I gave him a clear example of the virtual ToString method and he could not understand me, and overloading with method with same name but different arguments or type of value that the method is returning, the guy mentioned that I had no idea with that but I even gave him an example). • Entity Framework questions (what is a migration file?) • SQL | What is a view? (I mentioned that it was a virtual table that we can share to specific group of users in SQL to hide complex queries implementation and the guy did a bad expression in his face, he cannot think out of the box and doest not know that this is correct as he mentioned I was wrong.... Even there were no question regarding SOLID or design patterns....
