We have written a lot about logic puzzles of late. Logic puzzles are one of the newer ways that employers are testing applicants to see if they are right for the job, because your ability to understand logic reflects highly on your ability to problem solve. They are most common with IT job interviews, but it would not be a surprise if some form of logic puzzle was introduced to several types of job interviews.
Paying Attention to Your Own Thought Process
One aspect of logic puzzles that is often ignored when looking at these interview questions is your own thought process. Where does your mind go when answering these questions? Does it immediately go to an easy and uninteresting answer? Did you even have to think much about it at all?
The easy, uninteresting, thoughtless answer is usually going to be wrong. Remember, logic puzzles serve no value if everyone is going to have the same answer. Let’s look at a logic interview question that we have made up for the purposes of this post:
“You drive the speed limit on the freeway. Drivers are constantly passing you over the course of your trip. What, then, can we conclude about driving the spend limit in relation to other drivers? What percentage of freeway drivers drive the speed limit?”
This question has no actual answer. You are not expected to know any actual numbers. You are only expected to make a logical guess based on what you know from the question. If you go straight to the easy answer, you are probably going to choose a high percentage, like “90%” or “Most drivers drive above the speed limit.” This answer may be correct, but it does not show you used much logic. It’s simply an easy answer based on the question.
Better, More Logical Answer
“I would assume 10 to 20%, but probably not a very high percentage. Though it seems like you are often being passed on the freeway, that is only because you are only going to see the drivers that pass you. You will never see the drivers that are maintaining the speed limit since their distance in front and behind you will never change.”
Here we see a more logical answer, and probably a more correct answer. We don’t know for certain how many drivers drive the speed limit, but we do know that just because you see a lot of drivers pass you, it does not mean that most drivers speed.
Take this strategy into consideration with many logic puzzles. If the number seems to easy, it probably is. Look for ways to show that you put logic into your answer, and you are far more likely to succeed in the question.
