My interview got postponed twice and even I joined late in night. Third time when we connected interviewer started asking questions saying he only had thirty minutes, started with basic questions and raised the difficulty of questions when I didn't answer the last two questions he stopped the interview there where still 10min left and when I said I will explain about my project he said you don't have to you don't even have the knowledge and said there are people who have more knowledge with less experience. I know I am not an expert and I don't know all the things but you shouldn't judge people solely because they don't know something. I am a full stack developer it is hard to know everything in each language.
