Waymo Software Engineer interview questions

The interviewer provided an overview of the role and its responsibilities before diving into my resume. They inquired about my recent projects, previous work experience, and the technologies I have used in those projects.

I've got a chance to get through all the steps of the technical part. First technical screen call - great experience, I felt like I could give 100% of myself. Next round was 3 calls - coding, behavioral and home assessment. I've got the feeling that it went very well (I've answered all questions), I've got a very positive feedback after the first technical screen call. But unfortunately I didn't pass the second round. This time HR was not able to share with me a feedback - which I found a bit unfair - I have spent 1.5 months on interviews (feeling like it went well). I was left confused and still don't understand what exactly went wrong. Overall interviewing for Waymo it's a great experience and I will try one more time in the future.
