Interviewer asked many questions on spark, Python, scripting, architecture etc. On answering each questions, he was raising multiple cross questions. I kept answering them fully/partially as per my knowledge. He asked multiple scenario based questions. On one question, he gave me lot of time to hear that one answer which I didn't know. I gave him number of answers but he wasn't satisfied. Interviewer was least interested to know what I have worked on. Finally, they ghosted me. No updates, no interview feedback, nothing.
