Air India IOS Developer Interview Questions and Answers

Interview preparation tips for other job seekers - Though the interview questions were good however the interviewer's attitude was very bad from the beginning of the interview it seemed he was taunting the candidate also it seemed that he was laughing at the answer if it was not according to him.
First, he asked to write a code and went away from the call and I asked him to reply he might be doing some other work too. further, he asked a question and when I tried to answer then he told me "I am not asking definition", So how should I explain that without giving a definition? He should motivate the candidate not demotivate.
TBH this was my worst interview experience ever.
The interviewer might have more knowledge but was not professional.
