Sportz Interactive Senior Developer - .NET interview questions

First i got call from Sportz Interactive then Saturday i give the machine test and After 1 month i got the call for 2nd Round. in 2nd Round they are ask a outside technical question like why u r used this and What is Problem of this and That . they are totally disappoint to us. i would Suggest don't give a interview here it's Totally Waste of time.... HR Process is Very Slow....
