All RF Cafe quizzes would make perfect fodder for employment interviews for technicians or engineers - particularly those who are fresh out
of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons
who are going to be interviewed for a job.
Some of these books used in quizzes are available as prizes in the monthly
RF Cafe Giveaway.
Note: Many answers contain passages quoted in whole or in part from the text.
