poor standards of interview, initially asked couple byhearted interview questions, and then came reverse a LinkedList question, so i took couple minutes and presented solution, initially he didn't say anything, and then he said my solution is wrong, so i went through the code and an example as well, still not able find the flaw, then he said conditions while loop is not right, again i thoroughly checked not able find error, i asked why it is wrong and tried explained my code as well, but he is not trying understand and conducting interview as if interrogation and not uttering a word as if he revealing something, in-between he is saying its simple question, and he is typing something, seeing and comparing, finally i said ok, i don't know and assume i am wrong lets move next question, as i am losing time, he did similar stuff following questions, later i checked in google and finally realized that he is checking geekforgeeks code and comparing my code, first of all a question can have multiple solutions and later run my code it works the same, but he comparing loop to loop and variable to variable, saying my code is wrong, i tried to explain he does not even understand how to reverse linked list and saying very easy question and treating like interrogation, so disappointed.
