Top Engineer Interview Questions & How to Answer

Here are three top engineer interview questions and tips on how to answer them:

Question No. 1: What is the most challenging engineering project you've dealt with and how did you ensure its success?

How to answer: This question requires you to give a specific example. Ideally, you are able to choose a project that mirrors the type of work you would do in the role you are interviewing for. Even if it is not your most challenging project, make sure you describe your obstacle(s) and the successful outcome clearly and enthusiastically.

Question No. 2: In your current role, what steps do you take to avoid making mistakes?

How to answer: Whether you have a formal process or not, list any specific measures you employ (i.e. digital tools, consulting with colleagues, etc.). Make sure your answer demonstrates a commitment to quality control, efficiency and safety.

Question No. 3: Describe a time when you dealt with a difficult client or stakeholder.

How to answer: This one also requires a specific example that demonstrates patience and good judgment. An employer is looking for evidence that you are able to confidently and calmly stand by your decisions. Share an example with a positive outcome.

just some more info while we all wait(i know this process is painful- ive been through it a few times without good luck, unfortunately) June 13th is the tentative start date for ALL examiners for this round of hiring so that should tell you a lot. i just heard this today and apparently the Supervisors are apparently suppose to turn in their lists by tomorrow so calls/emails obviously follow after that is done. We might hear something later since the start date would be further down the road. i'll keep updating if i find out more or hear back from them. btw, the chemicals and computers i think hear back first and the electrical and mechanicals may hear back later as their interviews were conducted in that order.

I applied for EE position and just received notification that I have been selected. Last name starts with "C" and interviewed on April 13th. It seems that the selections for EE and Comp Science will begin to be sent today. It may take until Friday for HR to finish sending all decisions to the applicants. Best of luck to everyone and very grateful to all who have contributed to this posting. Less

How do you think you would respond if, initially, you worked hard on a task and yet your superiors repeatedly asked you to redo and rewrite, would you be frustrated by this?

On the same boat. I haven't heard back from Dallas neither. Did your status on USAjobs change with your tentative offer? Less

I neither declined nor accepted the offer, as I have not heard back from USPTO. Hope to go back into the review and change that setting on the post. I understand the 10 week cycle and the expectation of getting back to candidates within two weeks, but I was specifically told otherwise for this round. And I would accept this job if I'm selected.

Congrats on the interview. I had an interview on 12/7 too, for ChemEng in Alexandria. SPE I spoke with had said that I would hear back in two weeks; not sure if it's different depending on the job announcement/TC you applied to. Anyone else interview this week in Alexandria? Less

There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?

49 Answers

Swaz answer is almost correct however it does not work in all scenarios. lets assume: box 1 is labelled Oranges (O) box 2 is labelled Apples (A) box 3 is labelled Apples and Oranges (A+O) and that ALL THREE BOXES ARE LABELLED INCORRECTLY" Pick a fruit from box 1, 1) if you pick an Orange: - box 1's real label can only be O or A+O - box 1's current label is O - since ALL LABELS ARE INCORRECT then box 1's real label can not be O - box 1's new label should then be A+O by elimination - since ALL LABELS ARE INCORRECT - box 2's label is changed to O - box 3's label is changed to A - SOLVED 2) if you pick an Apple: - box 1's real label can only be A or A+O - box 1's current label is O - since ALL LABELS ARE INCORRECT then box 1's real label can not be O - this still leaves us with the choice between label A and label A+O - which would both be correct - FAILURE Solution: The trick is to actually pick a fruit from the A+O labeled box Pick a fruit from box 3: 1) if you pick an Orange: - box 3's real label can only be O or A - box 3's current label is A+O - since ALL LABELS ARE INCORRECT then box 3's real label can not be A+O - box 3's new label should then be O by elimination - since ALL LABELS ARE INCORRECT - box 1's label is changed to A - box 2's label is changed to A+O - SOLVED 2) if you pick an Apple: - box 3's real label can only be O or A - box 3's current label is A+O - since ALL LABELS ARE INCORRECT then box 3's real label can not be A+O - box 3's new label should then be A by elimination (not O) - since ALL LABELS ARE INCORRECT - box 1's label is changed to A+O - box 2's label is changed to O - SOLVED Less

It's easier to draw it out. There are only 2 possible combinations when all labels are tagged incorrectly. All you need to do is pick one fruit from the one marked "Apples + Oranges". If it's Apple, then change "Apple + Orange" to "Apple" The "Apple" one change to "Orange" The "Orange one change to "Apple + Orange" If it's Orange, then change "Apple + Orange" to "Orange" The "Apple" one change to "Apple + Orange" The "Orange" one change to ""Apple" Less

All the three boxes are names incorrectly. SO the bax lebeled Apples+Oranges contains only Oranges or Only Apples. Pick one fruit from it. If it is Orange then lebel the box as Orange. So the box lebeled Oranges contains Apples and the remaining contains both. Less

You have 2 pieces of rope, each of which burns from one end to the other in 30 minutes (no matter which end is lit). If different pieces touch, the flame will transfer from one to the other. You cannot assume any rope properties that were not stated. Given only 1 match, can you time 45 minutes?

47 Answers

Make a T. Simple

Take one rope (Rope A), place it down as a circle. Light match and start burning rope A at the tips that are touching. When the rope completely burns out, 15 minutes will have passed (since both ends are burning and being consumed at once). Hold the second rope (Rope B) straight and place one end so that it will immediately catch fire when the two burning points from (Rope A) finally touch and are just about to burn out. Thus 15 minutes on Rope A + 30 minutes on Rope B gives you 45 mins. Less

** You cannot assume any rope properties that were not stated Burn like this *-------- ===> After 30mins, Rope A finished burning, and both ends of Rope B start burning Less

Suppose you had eight identical balls. One of them is slightly heavier and you are given a balance scale . What's the fewest number of times you have to use the scale to find the heavier ball?

48 Answers

Two. Split into three groups of three, three, and two. weigh the two groups of three against each other. If equal, weigh the group of two to find the heavier. If one group of three is heavier pick two of the three and compare them to find the heaviest. Less

2 3a+3b+2 = 8 if wt(3a)==wt(3b) then compare the remaining 2 to find the heaviest if wt(3a) !== wt(3b) then ignore group of 2 discard lighter group of 3 divide the remaining group of 3 into 2+1 weigh those 2 If == the remaing 1 is the heaviest if !== the heaviest will be on the scale Less

2 weighings to find the slightly heavier ball. Step 1. compare 2 groups of three balls. Case 1. if they are both equal in weight, compare the last 2 balls - one will be heavier. case 2. If either group of 3 balls is heavier, take 2 balls from the heavier side. compare 1 ball against the 2nd from the heavy group result 1. if one ball is heavier than the other, you have found the slightly heavier ball. result 2. if both balls are equal weight, the 3rd ball is the slightly heavier ball.

Puzzle: How do you weight an elephant without using a weigh machine?

46 Answers

Not quite. The volume of the water is not the same as the weight of the elephant. You'd have to estimate the density of an elephant and multiply that by the volume of the water to get the mass, then multiply that by the acceleration due to gravity in water system (SI, English Customary, etc.) you're using. Luckily, mammals are mostly water (humans are around 70% water on average), so about 2/3 of the weight of the elephant would be equivalent to the weight of the water displaced. So you would have to estimate how dense the rest of the elephant is (since it'd be minerals and such, I'd say it's more dense than water) and follow the steps described above. Less

As it is not specified that the International System of Units must be used, define the Elephant unit (E) as the weight of your elephant. Your elephant then weights exactly 1E. Less

Simple answer : Use a beam balance . Put elephant on one side and start throwing weights on the other side . When the beam is balanced you got the weight of the elephant equal to the sum of weights on the other ! Less
