They really didn't ask any questions of me in the technical interviews. They ran exercises. In the hiring manager interview, she asked "what was your most impactful project" and "what did you do to contribute?" Fun fact - when I described a project and described how I contributed, she wanted details - like she didn't believe me. I get it, people are trying to sell themselves in interviews. But, I would challenge that the approach of the hiring manager here was more off-putting than helpful.
