Optum Technical Lead interview questions

3 Rounds, all theoretical questions on product architecture. 1st round was a good discussion, the interviewer listened what you were trying to explain. 2nd round, the interview was in a hurry. He asked about the class name we were using for business logic, not sure if he checking the naming conventions we are using for class name. For SQL queries, he wanted me write the exact query he had in mind, even though the my query was correct he told it was wrong. He questioned the architecture of my current companies product even though he did not listen fully. Overall it was a easy interview, but depends more on the interviewer whether you get selected or not
