TIAA Technical Lead - Java interview questions

Did the mistake of going for the interview in such company who don't value the candidates time , it was clear that they are only interested in doing marketing of the company with no intention of hiring. Process starts with the lecture about the company after that written coding test following by 3 technical and one HR rounds. They will take your all day, will provide you lunch(not good). Interview panel - Two inexperienced overconfident guys panel with attitude issues.
