For those interested in a career in academic mathematics, it's of course interesting to read interviews with mathematicians such as in Mathematical People etc. However, as far as I can recall, these are all extraordinarily successful elite mathematicians who have done groundbreaking or Fields-medal-calibre work. However, I do believe that "geniuses are not like the rest of us," and that it would also be beneficial to learn from people with a solid career in mathematics who did not reach such extraordinary heights. This could give a more realistic picture of how someone's career might shape after obtaining a Ph.D.
Has anyone had this idea before? Are there collections of interviews of not-particularly-famous research mathematicians anywhere?
