Pre employment test

Several large companies in Georgia are always hiring, Rogers Electric, Bryan Electric, Knight Electric out of Texas, and many others.

I wasted a year because somebody didn't embrace this idea.

As an incoming freshman, I took a placement exam. I didn't score well because my expertise in trigonometry was weak. The college looked only at the overall score, assumed that everybody took the same classes in the same sequence, and placed me in college algebra, which was a redundant waste of everybody's time. Next quarter, Calculus I, in which I just squeaked by. Next quarter, failed Calculus II. Finally took trig the second quarter of my second year and got back on track.

I like job-interview exams. Every time I've been given an exam, I've gotten the job.

I failed the math exam going into devry because I had never heard of a "j" operator and there were a bunch of problems involving it. Imagine my annoyance at having to take a remedial class in "j" operators. Turns out that for some reason in some electronic curriculums, complex numbers use "j" instead of "i". I did pass the rest of the test though. Fortunately, the "j" operator remedial class was only a few weeks long.

That's to avoid confusion with 'i' as current

 

[jim dungar]

In electrical engineering the "j" is used in complex numbers. I believe it came from the days of hand calculations and sliderules.
For the most part it is used to tell the difference between he resistive and the reactive components of numbers.

I find many of these types of general tests are better at finding out what is not known rather than what is known.

Good questions. In all fairness #12 has nothing to do with electrical work but I like the question and #9, assuming the answer is C, is incorrect for MC cable.

We also have an entry level quiz. Question #12 is a general knowledge question that displays a candidate's depth and the Moral Dilemma reveals outside the box thinking. We have had good success separating the wheat from the chaff.

So what's the answer to #12? And what do you think about question #9 being incorrect?

 

[petersonra]

Moral dilemma is not a dilemma at all. Any of the answers is morally defensible.

More to the point, if you find your soulmate waiting for a bus on a dark and stormy night, why would she get in your strange car, and what kind of soulmate is she really if she does.

Especially after your friend who you know, is also there, and you owe a big one to, says this other lady needs a ride to the hospital (right now).

I didn't like any of the #12 choices. I would get out of my car and let the friend drive the old lady to the hospital while I got to spend time hitting on my soulmate.

I am more interested in the answer to #8. In my opinion, it can't be A or B, because controlling current and voltage are integral, so either answer is every bit as valid. I am curious what the OP considers the correct answer.

 

[__dan]

I selected d. none of the above for 8. Actually I think "all of the above" would have been the correct answer.

If you are only offered one correct choice it would be, "as required by the manufacturer as a combination assembly", which would be 110.3 b in the NEC, and the ballast controls Voltage and limits current inrush to the lamp(s).

But the choice of "all of the above" or "as required by the manufacturer for their assembly" was not offered, hence d.

It could also be, "You are on a service call in a company truck so you better keep driving and get to your next location. I am not paying you to dawdle!"

#12

Moral DilemmaYou are driving along in your car on a wild, stormy night. You pass by a bus stop, and you see three people waiting for the bus: 1. An old lady who looks as if she is about to die. 2. An old friend who once saved your life. 3. The perfect man or woman you have been dreaming about. Circle who would you choose to ride in the car, knowing there is only room for one?

Easy, WIN, WIN, WIN

You give your old friend your car, to take the old lady to the hospital. That way your friend is out of the rain, and the old lady gets the needed medical help.

You stay at the bus stop with the "perfect mate" and keep them company. Everybody wins!

Marked wire, Nice one.
What if no marks?

"An example of this would be when you have Coil of wire come to site. Measure the mean dia (center to center) 36".
Count the number of wraps 44
How long is the cable in Feet?"

In reality the supply house reel set up is usually a 22" to 24" dia.
So use 23 mean dia and 24 wraps. Feet?

These are fun work questions. Get them thinking.

What if they memorized Table 8, and pull out a dmm with a calibration cert, and ohm out the coil, then do the math in their head, and give you the length +/- .1% in less time than the mean circumference math? Hired?

Knowledge is power, or at least, that's what I'm told.

MA. requires that HVAC techs have xhours of electrical code to get their HVAC license. I taught at the plumbers/pipefitters local some years back.

Amazing how hard it is to teach relays and motor starters. The Code was Greek to them. I taught a little Code. Stressed equipment grounding, wire size and breaker size MOCP and MCA.

I used to say if the circuit is grounded correctly and had the right size breaker and wire, and the wiring method was ok then it was probably ok.

Time was limited. I tried to keep them interested and teach them enough not to get hurt.

When it finally sunk in to one student that on a relay the coil was not connected to the contacts the light bulb finally lit up.


Unfortunately, most of them at school at night after working all day would rather play on their cell phones so I finally gave that up.
