Interview was very good and interviewer was polite and good but getting result was too late literally it takes 6 months for results after interview else every thing was good

Technical interview conducted. Java questions: - Polymorphism; method overriding, overloading - Inheritance and it's types - Exception handling SQL questions - 1 simple query based on filtering data with where clause - Joins types - Aggregate functions General questions based on previous experience But after that got an email from talent acquisition saying the there was a mismatch in the position to hire and the interview candidate.
