> nervous in interviews, or underlying general issues such as anxiety, or just being a very quiet person?

Yes, all three. The nervousness and anxiety are especially heightened during interviews, but I don't experience either on the job. Does that make me not a culture fit?

Well, if you have solid technical experience, but are being very nervous and quiet, and a recruiter tells you straight to face that "culture fit is more important", then the reason for failing 30/30 interviews seems fairly clear.

Why don't you A/B test yourself? Take double dose of your favorite anxiolytic and dress more casually to next interview and see what happens. If you fail again then it's 31/31 and not a big loss.
