onsite之后hr给我约了一个hiring maneger interview 请问这是什么操作? (startup 公司)

Thank you again for taking the time to meet with everyone.
As a next step, I’d like to coordinate a 45 min. Hangout interview with the hiring manager, John Smith, Lead Developer, and wanted to see what your availability is for this week.

请问大佬们可能会问什么东西和这一轮的目的? 谢谢

Most likely on your experience and the culture fit.

thank you!
