Google Associate Project Manager Carbon Offsets interview questions

Applied for the job in April and didn't hear anything until October. Out of the blue got an invitation for a phone interview not with a recruiter but with the hiring manager. Recruiter was friendly and scheduled the interview quickly. I had a good chat with the hiring manager from the sustainable operations team. She was hard to read at first and not particularly chatty. Asked only specific questions related to the job. Both experience working with different internal company groups (accounting, legal, etc.) and technical. How to evaluate additionality of a carbon offset and given some parameters, was a certain project a good investment. By the end we were having more free dialogue. About 4 days later recruiter contacted me via email to chat via phone. Spoke candidly on the phone. I guess they thought I was a good candidate and wanted to fly me out for the next phase of interviewing, but had 2 others scheduled for in-person interviews that week. Following those interviews, they called to let me know that they were planning to make an offer to another candidate and would keep in touch if that fell through. The recruiter was very friendly and forthcoming with details and kept in touch well. Ultimately I'd love to work for Google but the stars didn't align this time.
