They called me for face to face interview for Senior software engineer in c++. Company seems to be OK but my interview experience is horrible or comical. I dont know what suited best . This guys asked me some basic questions about c++ and Linux. One of the most idiotic question asked . Suggest me any good practice to achieve late binding polymorphirmsm. I was like good practice is to be, take care of function signature , it should be same and even no const difference. But he said there is one more thing, i said what , he said, you have to place virtual. OMG how on earth he is going to achieve late binding without virtual keyword. He said that is a good practice. I said that is a must condition. He even doesn't know about c++ in depth . Other question asked : What is copy constructor and == operator overload , strstr function . They asked such silly questions to 8 years exp. guy. I have answered all questions.
