Visa Inc. Senior Staff Machine Learning Engineer interview questions

2 interviews back to back, both 45 minutes. 1st Interview was coding round: Asked me to go through and explain one of my projects from Github. After that asked a few technical GenAI related questions. 2nd round System Design: The interviewer was weird. The tone of all of his questions was as if he was trying to challenge me, and to make it worse he was all the time. He was not getting what I was trying to explain and was laughing and when finally understood then he stopped. but I didn't like the attitude. Question wasn't a very difficult one.
