Tell me about a problem you faced recently where you were unsure of the answer. How did you research the problem and find a correct solution?
Many engineering positions require a structured method for solving problems. Following a problem-solving method shows that you are efficient and can produce measurable work. Each position is different; some jobs will require you to solve problems quickly, while others will allow you to gather data. Some problems may require you to consult with outside resources and others you will be able to solve using information already available. Read the job description to gauge what kinds of problems you will likely have to solve and answer accordingly. The example answer is for an engineer who has previously worked in manufacturing.
"In my previous position, we had an issue where conveyor belts were wearing out more quickly than the manufacturer said they should. We tried replacing the belt and adjusting the tracking more often, but it wasn't solving the problem. Then, I tried using the Root Cause Analysis method of problem solving. After defining the problem, we dedicated two months to collecting data about the belt wear. Then, we made a list of all the possible factors, including the roller, the material the belt was carrying, etc. We figured out that not all of the material was leaving the belt, some of it was getting stuck in the belt and carried back. From there, we were able to come up with a couple different solutions."

We were experiencing inexplicable scrap due to dimensional variations on a product on different days despite no changes in production equipment or material. It was always assumed that it was due to the volatile plastic layer that was causing the issues. After researching the characteristics of both the MDF substrate and plastic material, I conducted DOE to study the temperature and humidity impact on the materials. It was determined that a combination of moisture and heat can adversely affect the wood core MDF and thereby potentially causing the product to be non-conforming. The plastic was not greatly affected by the temperature and humidity variations. Controlling these environmental elements allowed us to eliminate these scrap variabilities.

This year ______ executive management asked me to create a new team with an industry focus that supports 60% of the ____ sectors they asked me to support or 10% of 950M. For context, North America brings in 1.5B of 5B of DS revenue. Of the 1.5B, I support 64% or 950M.
In January, we had no structure, history, know-how, any precedence to follow. I have good judgment and instincts and know how to invent and simplify best practices so I had to quickly, hire, create a fast track onboarding and ramp up plan. Then I created processes and structures of how to proceed.
I am very happy to report our H1 results are 185% of the plan.

Awesome! Great answer. What kind of research did you conduct to figure out how to hire and onboard your new team, in addition to creating processes and structure? Show the interviewer that you are resourceful, quick thinking, and decisive.
