easy interview write a program to find the duplicate data from array. c#,oops,mvc, middleware,routing, dynamic vs var,using,sp vs function,partial view,temp vs view data,out vs ref, union vs sp ,session,exception handling,filters in mvc

First discussion on telephonic asking about salary expectation and then Technical virtual interview. All was good .and then again HR round was simple discussion and salary expectations. but I guess they don't have budget to hire experience candidate. Overall very bad experience.
