Tata Consultancy Services Software Developer Java Developer interview questions

Interviewer was highly unprofessional, i tried to clarify on what he was asking and he proceeded to reply me condescendingly on how can i not have heard about the terms before. Which was what i tried to clarify with him as i do not know the official naming terms of the things he was talking about (even though i've worked on it before after looking up what he was referring to, although the questions he asked are rather basic, just that i did not knew the technical term for it like method referencing and functional interface) Some clarification would have helped a lot. Then because his mic is also really muffled, it was difficult to make out what he was saying, plus he had an indian accent which added to the difficulty of understanding. When i asked him to repeat his questions a few times as a result, he told me he cannot keep repeating his questions and that his mic was fine and it was clearly my problem. If u encounter an indian interviewer for ur technical interviewer, i wish you good luck.

Had a technical interview. I should open my desktop for writing some codes for answering their question. It was about coding and object oriented concepts and sql queries. Some question about my previous expreience.
