Focus Softnet .NET Developer Fresher interview questions

They conducted a apptitude test in our institution.after that they called to the office for technical face to face. They asked me the simple logical programs regarding prime numbers,array,factorial . Some SQL queries about joins,N th highest salary.i answered 95% questions perfectly. They finally they said thank you. I didn't understand what are they thinking.at least they have to give feedback. Interview persons are not good.they don't have full pledge knowledge . they did not single question from asp.net and mvc.
