very nice job. Thanks to uploader. Interviewer voice is very hazy, whoever understands his questions, can you please mention in comments. Thanks to interviewee for repeating the question sometimes before answering.

[@anjaangupta9519]

Can you just upload recent as possible sir

[@dileepmaurya9009]

you should listen whole question at least. in every question you always start speaking in between

[@paragranjan8818]

Its Maybe Annoying For The Interviewer but in the Same time it gives the impression of How Confident he is in his Java Concept

[@rexsam3134]

@@paragranjan8818 who cares about impression. Any developer had to listen first. It's called over confidence, over smart etc
