Very good! The candidate should tell: a. the parts are historical and not compliant for new designs (but very good for hobby). RoHS is not a problem of basic principles of electronics but a manufacturing one. b. power supply, signal generator, oscilloscope, DVM is must for solving any problem involving electronics (those are given by default). c. at least the following things can be designed with those parts: repeater, inverter, integrator, derivator, log amplifier, comparator with enhanced output current d. some more passive components would be necessary for a precise design Such question involves basic knowledge and creativity. The same types of questions should be defined for embedded systems or other electronic field (such RF, mixed electronics, etc). I have somewhere a test given in 1960-1970 to the US military technicians. Is a very good one, I will search for it. The multiple choice test will never tell if the candidate will be able to design something in his lifetime, just that he has good memory, fortune or knowledge.
