Very long waiting time...less number of panel..I felt panel itself was exhausted or not well prepared. Lack of basic java concept. Make sure panel is strong enough to take someone's interview As per the panel 1.overloading can never happen in parent child class. Only overriding is possible. 2. Final doesn't ensure a variable to be constant. 3.confused about Singleton and immutable class. 4. No class is derived from Object class. 5. Not aware of the concept of constructure chain. As per him object class constructure never called.. Above are basics and he is not aware of java concept. He will make you feel that you don't know java. I told I m not good in a particular area, he started asking questions on that.multiple times I told I never worked on this particular are, but he was like you try to answer something. Don't know what he was expecting. Pathetic interview. If you really want to make jokes of what you have learnt, then go here. Don't waste your time here. I will suggest at least having system while taking interview make sure , interviewer should Google and know the correct answer.
