[PSES] Interview Questions

[Kevin Robinson]

Hello All,

I have recently been tasked with writing a set of questions that job
candidates would need to answer at the same time they apply for a
position requiring  knowledge of product safety evaluation, testing
and practices.  These questions would serve as an automated pre
screening mechanism.  Questions like "What does the term creepage
distance mean?" would be perfect , however the challenge that I am
facing is finding questions that the answers are not easily found
using Google.  If anyone has any product safety related questions that
they would not mind sharing, I would greatly appreciate it.

One way is to ask the question 'backwards' - 'What is the distance 
across an insulating surface between parts at different potentials 
called?'

Well don't try - "what is the sound of one hand clapping" I asked Siri (iPhone 
assistant thingy) and she gave me an answer. (Silence)
Try to avoid definitions and work the question so they have to demonstrate 
knowledge of what things do.
You might try, "if you have inadequate creepage distances what alternatives 
might be available? (through insulation is what I had in mind) 
They can look up creepage distance all night long but unless they known a 
little something about what is being accomplished with creepage distance they 
can't come up with an alternative.

Re: [PSES] Interview Questions

[Nick Williams]

This has the makings of an extremely esoteric pub quiz, if we're not careful!

Here is one, adapted from a phone enquiry I dealt with this morning this 
morning: 

You have two appliances. One is marked "110 - 230V ~50Hz" and the other is 
marked "110/230V ~50Hz". What do you look for on one which is missing from the 
other? 

I'll let the group answer. 

Nick.

Re: [PSES] Interview Questions

[IBM Ken]

You could ask them for a hipot voltage per 5.2.2; I don't believe the table
is available via google;  you would also be able to evaluate their useage
of the table, conversion from RMS to Peak voltage, AC vs DC, etc.

You could also ask them to summarize the requirements for a fire or
mechanical enclosure; things like that would require more experience than
just reading 60950...

Re: [PSES] Interview Questions

[IBM Ken]

Not sure this is what you are looking for; but the 110-230V unit is rated
as a range, so the tolerance would be below 110 and above 230.  The 110/230
V has two distinct rating ranges, so the tolerances would be above and
below 110 AND above and below 230VAC.  That's the first thing that pops
into mind, anyway.

PS: Who operates at 110VAC 50Hz?

Re: [PSES] Interview Questions

[Brian Oconnell]

Pre-screens that attempt to minimize consumption of a candidates' time is a
good thing.

What if the candidate logs in to answer one or two questions that evaluate
engineering judgment and/or problem solving? Perhaps you have to consider
that the  "knowledge of..." stuff cannot be used as a first-pass screen.
This is best evaluated in-person.

I have had several interviews that focused on knowledge (facts) questions -
useless if it is something that can be looked up by a 2-second computer
search of the a standard or on-line data. The more obscure the knowledge
element, the more likely that it can be rapidly found with access to the
correct documents. With exception of one company, I am glad that they
('fact-based' interviewing companies) passed me up or I passed the company
up. A fact-based interview is shallow. Problem-solving interviews indicate
depth of thought by both the interviewer and the interviewee. Realize that
the superior candidates will also evaluate the interviewers.

The best compliance-related questions that have been posited to me follow:
1. After a few minutes discussing the circuit in a schematic - 'What is the
method that this converter uses to detect overload, how would Type-Test it,
and why?'
2. Is this code safety-critical? Why or why not?
3. Provided simple fly-back converter schematic and PCB layout and WV table
and calipers - 'Evaluate the spacings and provide general component
requirements for the circuit node outlined on the schematic'.
4. 'Do you prefer Agilent or R/S? Why?'

Re: [PSES] Interview Questions

[Aldous, Scott]

I believe Nick may be fishing for the answer - a voltage selector switch.

Back to the original question... Of course, an interview is much better for 
assessing this type of knowledge, but if you have to have questions on an 
application where candidates fill it out from home, you could ask questions 
based on personal experience, such as "describe an experience you have had 
where you solved an issue with creepage distance and how you did it" or 
something like that. People could always just lie and make something up, but it 
should be pretty easy to tell if someone has no idea what they're talking 
about. Much harder to Google this type of specific problem and solution, I 
would think.

And a voltage switch is NOT necessarily required. Think auto-switch power

Not sure this is what you are looking for; but the 110-230V unit is rated as
a range, so the tolerance would be below 110 and above 230.  The 110/230 V
has two distinct rating ranges, so the tolerances would be above and below
110 AND above and below 230VAC.  That's the first thing that pops into mind,
anyway.

PS: Who operates at 110VAC 50Hz?

I think it was just an aside question. But Japan is 100 V, not 110 V.

That DOES a better compliance person. Some would (in error) say 
'110/230' marking demands a selector.

I believe Nick may be fishing for the answer - a voltage selector switch.

Back to the original question... Of course, an interview is much better for 
assessing this type of knowledge, but if you have to have questions on an 
application where candidates fill it out from home, you could ask questions 
based on personal experience, such as "describe an experience you have had 
where you solved an issue with creepage distance and how you did it" or 
something like that. People could always just lie and make something up, but it 
should be pretty easy to tell if someone has no idea what they're talking 
about. Much harder to Google this type of specific problem and solution, I 
would think.

Pre-screens that attempt to minimize consumption of a candidates' time is a
good thing.

 

Reminds me of back around 1994, when I interviewed at a now World-famous
company for a position as an EMC engineer. I spent a very long day talking
with 5 engineering groups, each of which had classic problems (shielding
effectiveness, internal coupling, export compliance, CE & RE). While I can't
say I fixed every problem, I was able to set each group on a righteous path
to their goal. And a few days later, their HR droid told me that, on
reflection, they now thought they didn't really need a full-time in-house
EMC guy. So that's how they were so profitable!

 

The best compliance-related questions that have been posited to me follow:

4. 'Do you prefer Agilent or R/S? Why?'

 

Hey, don't diss the Anritsu & Thurlby guys!

Nice approach!   I suppose it would be harder to find an answer to that 
question by a simple Google or two.

One way is to ask the question 'backwards' - 'What is the distance 
across an insulating surface between parts at different potentials 
called?'

Re: [PSES] Interview Questions



Well don't try - "what is the sound of one hand clapping" I asked Siri 
(iPhone assistant thingy) and she gave me an answer. (Silence)
Try to avoid definitions and work the question so they have to demonstrate 
knowledge of what things do.
You might try, "if you have inadequate creepage distances what 
alternatives might be available? (through insulation is what I had in 
mind) 
They can look up creepage distance all night long but unless they known a 
little something about what is being accomplished with creepage distance 
they can't come up with an alternative.

Hello All,

I have recently been tasked with writing a set of questions that job
candidates would need to answer at the same time they apply for a
position requiring  knowledge of product safety evaluation, testing
and practices.  These questions would serve as an automated pre
screening mechanism.  Questions like "What does the term creepage
distance mean?" would be perfect , however the challenge that I am
facing is finding questions that the answers are not easily found
using Google.  If anyone has any product safety related questions that
they would not mind sharing, I would greatly appreciate it.

110 V~ 50 Hz countries:

Jamaica
Lebanon

Some selected areas in some countries may have 110 V~ even though that 
is not the norm for the rest of the country.

Not sure this is what you are looking for; but the 110-230V unit is

The 110/230 V has two distinct rating ranges, so the tolerances would 
be above and below 110 AND above and below 230VAC.  That's the first 
thing that pops into mind, anyway.

PS: Who operates at 110VAC 50Hz?

You have two appliances. One is marked "110 - 230V ~50Hz" and the
other is marked "110/230V ~50Hz". What do you look for on one

I'll let the group answer.

Re: [PSES] Interview Questions

[Ted Eckert]

I think Ken is on the right track. Railroad signally and portable equipment 
both represent areas where there is a higher risk of exposed connections. 
Receiving a shock from 110V is unpleasant, but it is less likely to lead to 
significant harm than a 240 V shock. I've contacted 110V a number of times and 
it seems to have had no ill effects other than starting e-mail messages with 
bad puns.

Re: [PSES] Interview Questions

To keep people from stealing the bulbs?

Heh.

Wikipedia says 110 or 120 V are used for traction on a couple of lines, 
most higher, some MUCH higher. Perhaps I'd have learned more if I'd 
gotten the job at Kawasaki's New York railcar facility.

Actually Edison Illuminating Company of America installed the first electric

what they were experienced with ... and because its safer.

The UK railway hasn't changed it since.

I think Ken is on the right track. Railroad signally and portable equipment 
both represent areas where there is a higher risk of exposed connections. 
Receiving a shock from 110V is unpleasant, but it is less likely to lead to 
significant harm than a 240 V shock. I've contacted 110V a number of times and 
it seems to have had no ill effects other than starting e-mail messages with 
bad puns.

Bolivia has a 50Hz grid, but some parts of the country operate at 110V while 
other parts operate at 220V. There is some mixing of the 2 voltages in some 
areas. I was in a room in La Paz where one side of the room was 110V and the 
other side was 220V, with the same type of receptacles and no markings!

other parts operate at 220V. There is some mixing of the 2 voltages in some 
areas. I was in a room in La Paz where one side of the room was 110V and the 
other side was 220V, with the same type of receptacles and no markings!

Portable equipment used on construction sites; it's actually 55-0-55, with the 
centre grounded.
