A friend who works at a startup was recently explaining that the company’s biggest problem at the moment is its inability to find suitable engineering talent.
As a barometer, one of the "questions" it poses to interviewees is this:
You have a 10V ideal voltage source in parallel with a 5Ω resistor. What is the impedance?
So far, no one has answered correctly. (The answer is provided at the end, in case you want to take a shot at it.)
My friend says, “Engineering students today can't answer basic engineering questions. And we aren't talking about tier 2 or 3 universities, either.”
She tells the story better than me, so here are her words:
This is a well-known problem, one which I have discussed/commiserated with friends from two other firms with the same issue. One is in Massachusetts and the other is in Texas, so clearly this isn’t just a regional thing.
When you look at these people's resumes, all is sunshine and rainbows. When you ask them questions about their accomplished projects, it becomes clear that they have no clue what these so-called projects were really about. They can't answer. And not just undergrads; we rarely interview undergrads. We are talking about folks with MSs and PhDs.
Some are specialized to the point of absurdity, which I suppose makes some sense if you are going to be writing a thesis, but because they lack basic understanding of the underlying physics, they really don't know their specialties all that well, either. Plus, many have difficulty communicating in English.
The bottom line is that the schools are to blame. They should not be graduating people who do not understand the material they were taught.
She went on, including what she considered unrealistic salary expectations, but you get the gist of it. Are you seeing a similar situation out there? Tell us about it in the comments section below.
Spoiler alert: The answer to the question is 0. It's a trick question. The amount of the voltage is irrelevant. The key phrase is "ideal voltage source." The real purpose was to see if they knew what an ideal voltage source was.
LO!, all those decades ago when I was but a high school graduate preparing for my college experience, a sage (uncle) once told me something that I've NEVER forgotten ..... "the fundamental purpose of a college education is to teach you to THINK!" (He told me some other things too, but I can't repeat them in mixed company! Ha! Ha!)
I-B-M thought so much of this concept of thinking that for a long time they distributed throughout their facilities various-sized desk ornaments w/ the one word, "THINK" inscribed on the brass placard. And, anyone in this audience who is old enough should remember seeing photos of the I-B-M 360 main console w/ the THINK placard proudly displayed on the top surface.
I have to agree here. The question is not specific enough for engineering. You might have well have been asking "Where did they bury the survivors..."
The purpose of the interview is not to see how well the candidate guesses, but how well they think.
I put together a test of 20 questions for an engineering candidate. However, the purpose was not to give a piece of paper to the applicant and walk away, but to sit there with them and have them talk out their thought process for each question. I never graded the test on right answers but how they were thinking. Sure, we're all too busy to do this, but if you want to find a good candidate, you have to put some work into it. It's either that or hope you get lucky.
The problem with onesy questions like this is that they get out and then everybody, even the biggest idiot, knows the answer. Don't go for the answer, go for the thought process.
I am not too sympathetic to corporate world complaints of lack of qualified personnel. It is not neccessarily true that the point of college education is to support the corporate world. People go to college for a variety of reasons. The corporate world basically bailed out on training and developing people after the '90s. Besides, like everything else in business, it's all relative to competition. Hire the best people available for your purposes based on a comprehensive evaluation, not trick questions. If you are more successful at getting the best candidates than your competitiion, you will benefit in the free market.
I also look for hobbies on resumes when I have to interview. I still do the testing and the interview, but I sometimes look at a weaker resume because the candidate may have listed a useful hobby. As you can tell by my screen name I tend to be partial to car guys. But this also translates into a person who has some basic hands-on skills that may not always be related to the target job. But hobbies are usually self taught or mentored. This means the person can learn!
I like your approach, Greg. Candidates should definitely have a core understanding of the foundational principles and theories, and sure, a co-op and hands-on practical experience is a huge plus. But those coming out of school likely aren't going to have deep expertise in many of the skills needed in today's jobs. Yet as long as they demonstrate a hunger to learn and a willingness to role up their sleeves and dive right in, I think that's half the battle. I think some coming out of college have expectations that they don't have to start at the bottom and work their way up through hard work and hands-on training. They want the big job right out of school and all the perks that go with it.
" I think you dismiss PhDs a bit too swiftly in too general a manner."
Point taken. I didn't mean to be swift and general in dismissing PhD's. I was really trying to make the point not to be swift and general in dismissing non-PhD's, and even non BS's.
I believe a lot of productive talent is overlooked by indiscriminately filtering candidates by degrees. There are many people who have the raw material to be very good engineers, but they don't have the guidance around them, or the financial resources to seek the "appropriate" education. They might, however, find their way get through a 2 year program at a tech school. I think our current HR structure overlooks these people (by "degree as a litmus test" practices), and does so to the detriment of everyone involved.
If you need a PhD because of the nature of the position, by all means, look for a PhD to fill the position. Most work that needs to be done doesn't need to be done by PhD's, however.
I completely agree with your differentiation between PhD's who only went to school, and those who went back after/during work.
ttemple, I think you dismiss PhDs a bit too swiftly in too general a manner. I would look very differently at a PhD holder who earned it in one continous educational period, from B.S. to PhD, than I would someone who worked in industry for a time with a B.S. then went back to school to earn the PhD.
That second candidate is likely to be much more grounded and useful, and the PhD itself more useful to your company.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
