Paxcom Software Engineer interview questions

Horrible Interviewer. It was a telephonic interview. The interviewer came 10 minutes late. Didn't ask for an introduction, went straight to questions. The duration of the interview was 30 minutes. First question: What is a string? I answered: String is a sequence of characters and a data type. Interviewer: String is a class. (get rude now, starts switching languages between Hindi and English). Gets adamant that the answer is a class, gets me to google "what is a string?". Top google answer is "It is a string of characters." Gets mad and 5 minutes later asks to specifically open some site where it is written that it is a class. Rest of the interview goes in the same way. At the end, I asked for feedbacka and rudely replied "Why do you want feedback? I will give feedback to HR. Go read GFG and get some knowledge." P.S.: String is a sequence of characters, definition of string on GFG.
