I was asked about a simple light bulb circuit and how to test it. Also asked about troubleshooting a line of switches in series with 1 open/ not working. Next time I think I will tell them it is stupid and that all switches and bulb or call button would be in Parrellel. It was confusing

I am older 50's and hope it wasnt age discrimination. I also was offered a job in 1993 but had smoked some pot. Not good. I since havent smoked anything and really hope that that isnt why I am not given another chance. Less

Pertaining to the switch question: They were trying to get you to say, "you would have to isolate each switch, because a continuity test would be inaccurate in a parallel circuit, and ultimately would not help detect which switch was open/not working." Less

Actually, the question was for a series circuit. Although, yes, it would be stupid to wiring switches in a series; basically one switch would be directly powering the following switch and so on, rather than splicing the main hot and using a jumper to each switch (i.e. parallel). If said switch actually was stuck open all subsequent switches would not receive any potential( i.e. power). Depending on the scenario, there are a number of possible ways to solve the problem. If all switches are exposed (i.e. testable), then you turn all switches on and you could simply test the output terminal for each switch. Eventually, you would find a switch that is not receiving any power on the output terminal. If you were testing the contacts of a relay you would have to follow the same type of procedure, but you would also have to refer to the schematic to ensure that the contacts are not supposed to be "normally open." If the contacts are supposed to be "normally closed", but they are stuck open it might be due to the contacts simply being stuck open, or there might be a short across the relay coil which has caused the contacts to become open for some reason.

I indicated that I could do a variety of jobs but was unwilling to make the trip in unless they were trying to fill a specific position. I'm too busy to run a wild goose chase. Less

Wise move not to bother with them... their recruiters are required to interview a specific number of people in office per week, regardless if they have an actual position or not. Telling you there were several you might be a fit for is just a lure to get you to come in. Less
