Domande di colloquio per Java Software Developer presso InputZero

I was interviewed on july 2019 in bengaluru. So, actually in 1st round they took mcq questions on java, it was 40 qs in 30 mins of moderate level with negative marking of 0.5 if 3 wrong. In the next round it was f2f. I believe that interviewer was not so much interested so, after asking formal intro he asked me oops concept polymorphism which i explained and then again he asked me about overloading and overriding. This time i explained him in paper. Next he asked me one question which i wrote and described him but he told it can't be solved that way and told me wait outside. I waited for about an hr and the hr was busy in something else only then she told me that no one is available for the interview today so wll call again next week upto which i replied I am working can't take leaves every week so she arranged the interview any how. Third round f2f started with formal introduction and he asked me 3 coding questions to write. I wrote all three with optimized solution of two. The stupidest thing i ever heard from hr that time was "you were good at the rounds and everything was fine but we are looking for some 1-2 years experienced developer" So, basically you called me to waste my time. It was just waste of time and worst experience of interview.

first round was written exam where basic aptitude and java questions asked. second round is technical which is basically on skype and the third is also technical round through skype
