Uber Software Engineer interview questions

Got onsite interview after a simple phone interview. There are 5 rounds of interviews in the onsite day with lunch. 1. go deep into your projects 2. coding Lunch 3. culture fit (behavior questions with the manager 4. System design 5. OOD and coding I got rejected after 5 days of the interview. Since I think I did well in the interview, I asked the recruiter twice about my weakness in the interview, so that I can improve the next time. However, the recruiter never replied my email. Bad experience.

The first interview was with the recruiter ,then I talked to the hiring manager. He asked me technical questions about motion planning and decision making and some data structure. Then they sent me a homework assignment which was a project on data structure in C++.
