The interviewer was not interested to take the interview. She asked me to wait for 5-6 minutes. Then I started with my background and technologies. She was interrupting me again and again like I have been lying on the face. Then she asked have you worked on kafka and as I said No, she totally lost her cool. No She gave me to write code to fetch login details from KafkaUtils class in case of multithreaded environment. I tried writing some code in a pseudo code form and she was constantly pin pointing the mistakes and that too in non constructive way. Then she asked me to write a code for ds problem. It was a medium problem. I made a little mistake in the code and she said ok we are done. Later on right after the call I saw that its a variable that I took incorrectly but she didn't understood or didn't bother to advice on that. She asked multiple questions on Microservices and monolithic applications as well. I answered well but she only wanted to hear the answer she knows.
