I had an interviewer ask me to picture a cube of wood painted on all sides, cut three times through each face (like a Rubik's Cube). How many of the resulting pieces are painted on two sides? Three sides?
Engineers find it difficult to believe that non-engineers have difficulty visualizing things like this.
If I understand this correctly its essentially a voltage divider circuit, where you want Vcap to be within 10^2 / 2 of Vsig. Vcap / Vsig = 1 / sqrt(1+(2*pi*f*C)^2).. Seems like a pencil would come in handy.. Unless I'm totally mistaken
The problem with 'questions that a real engineer would know the answers to' is this: I'm most emphatically NOT an engineer, damn, I can hardly keep pico, femto, nano and nono farads straight - I'm a hobbyist. But I know the answers (yes, without cheating) to the 'DIP' problem, 0 = 32 and 212 = 100, -40 = -40. So there's some right, right off the bat. The 'high voltage' question I'm guessing is lower current, reduced copper required, lower heat (and I'm hoping that whoever corrects me is polite) and the most important question, the difference between static and dynamic ram? The static ram is dead, the dynamic ram is frolicking with the sheep.
At one job interview I was asked to the lab to demonstrate I could use a current probe and digital storage scope to measure the startup current surge of a piece of equipment. Did that easily, but still no job.
Another interview I was drawn a diagram of RF amplifiers, attenuators, splitters and was asked to determine the final output with 10 dBm input. The interviewer did not agree with my answer, he had forgotten that a 2 way power splitter is -3 dB, not -6 dB. After we discussed his error he said "Do you realize how many candidates cannot do this?" Got the job.
The Other Tesla David Blaza5 comments I find myself going to Kickstarter and Indiegogo on a regular basis these days because they have become real innovation marketplaces. As far as I'm concerned, this is where a lot of cool ...
