Infosys Systems Engineer interview questions

Great! The interview was scheduled after clearing the online test which contained aptitude; verbal, puzzles, English grammar, numerical reasoning, logical reasoning and technical; Programming. In the interview I was asked about my projects and was asked couple of programming questions.

They saw my resume and asked to explain one project. Mine was related to java so they asked how confident are you in java. I said 80% (big mistake) , they said even they dont know that much (neither did i). I had the idea that they will ask very basic qns related to cs or core java max , but after i said 80% they started with inner working of hashmap , prepared statements , future keyword , autoboxing etc etc. i said most i could but it was not to my level of answer because i hadnt done revision on these topics at all. Got the role nonetheless as i think interview had 10% say in getting the role , if you are selected for interview you are passed already.
