Elements of Programming Interviews: authors include an algorithms professor, a software engineer, and an engineer/CTO.
Programming Interviews Exposed: authors include software engineer, a CEO & VP Technology, and a radiologist. (Note that this book was written a long time ago. The radiologist probably was a programmer at the time.)
Ace the Programming Interview: software developer
Data Structures and Algorithms Made Easy: software developer
Out of 9 authors (including myself), 8 are/were software developers or something else very, very deep in technology. Possibly all 9.
