1) Showed me a waveform and asked me what kind of radar emitted this kind of waveform. 2) Showed me a Darlington pair and asked me what kind of characteristics this circuit had. 3) Asked me how long it would take a battery (with a stated capacity) to drain when connected to a resistor of given resistance and two LEDs (of known voltage drop and current draw). A total of 12 questions.
