I'm not concluding that it's simply ageism, because this is feedback I'm getting from mock interviews, not real ones. Professionals tend to be more honest and open about how you interview if it's just for practice.

However the fact that you are using numbered levels instead of broader decscriptors like "junior" and "senior" means that we are thinking on different wavelengths. I guess you're talking Google-ese because it is harder to know what is "L3" without context.

I have obtained various kinds of feedback and working on some of my weaknesses, but "underqualified" and "repeating the same basic experience many times" are the most common themes.
