11. What is your favorite part of the Engineering Design Process?NEWBehavioralEasyGe Aerospace

Question Details

Identify the part of that process you most enjoy.

Interview tip:

Use STAR to structure your answer: briefly explain the Situation and Task, make Action the most detailed part, and finish with the Result. For example, describe a design project where you most enjoyed developing and evaluating concepts, explain how you compared options, worked with the team, made design decisions, and used what you learned to improve the final solution.

Situation

During a previous mechanical design project, my team needed to improve a component that was difficult to assemble and also had to meet strength and space requirements. My favorite part of the Engineering Design Process became the concept development stage because it gave me a chance to turn the problem into several practical design options.

Task

My responsibility was to develop possible concepts, compare their strengths and limits, and help the team choose a design that could meet the main requirements without creating unnecessary manufacturing or assembly problems.

Action

I first reviewed the design requirements so I understood which constraints mattered most. I then created several simple concepts instead of becoming attached to the first idea. For each option, I looked at load paths, available space, manufacturability, assembly access, and the number of parts required. I used basic calculations and CAD models to check whether each concept was realistic. I also discussed the concepts with teammates who had different responsibilities because a design that looks good in CAD can still create problems during manufacturing or assembly. I compared the options based on the same criteria and explained the tradeoffs clearly. I especially enjoyed this part because it combines creativity with engineering judgment. You can explore different ideas, but every idea still has to satisfy real physical and practical limits. After the team selected the strongest concept, I refined the geometry and checked that the design still met the original requirements.

Result

The team moved forward with a design that was simpler to assemble and met the key engineering requirements. The experience reinforced that concept development is my favorite part of the Engineering Design Process because it is where I can combine analysis, creativity, communication, and practical judgment to turn a problem into a workable solution.

Why Interviewers Ask This

Interviewers ask this question to understand which part of engineering work naturally engages the candidate and how the candidate approaches design decisions. A strong answer shows genuine interest in the design process, practical engineering judgment, awareness of tradeoffs, and the ability to connect personal preference with effective mechanical engineering work.

How did you decide which design concept was the strongest option?

I compared every concept against the same requirements instead of choosing based on preference. I looked at strength, available space, manufacturability, assembly access, and overall simplicity. I also used feedback from the team to identify practical issues that were not obvious from the CAD model. That helped us choose the concept that best balanced the important constraints.

What did you learn from developing several concepts before selecting one?

I learned that the first workable idea is not always the best solution. Creating several concepts helped me see different ways to solve the same problem and made the tradeoffs much clearer. It also taught me to involve other team members early because their input can reveal manufacturing or assembly concerns before too much time is spent refining one design.

12. What was one engineering process you improved?NEWBehavioralMediumGe Aerospace

Question Details

Use an engineering process you personally improved.

Interview tip:

Use STAR to structure your answer: briefly explain the Situation and Task, make Action the most detailed part, and finish with the Result. For example, describe a mechanical engineering process that was causing delays or inconsistent results, explain your responsibility for improving it, show how you identified the cause, involved the right people, introduced a practical change, and verified that the new process worked better.

Situation

In my last role, our design review process for mechanical parts was taking longer than necessary because drawings often reached the review stage with missing information. Reviewers would send them back for dimensions, tolerance details, material notes, or manufacturing information. This created repeated review cycles and slowed the release of drawings.

Task

I wanted to improve the process so drawings were more complete before formal review. My responsibility was to understand where the repeated issues were coming from and introduce a simple process that improved consistency without adding unnecessary work for the design team.

Action

I first looked through several recent drawing reviews and grouped the comments by type. I found that many comments were not complex design problems. They were basic items that could have been checked before the drawing entered formal review. I then spoke with other engineers and manufacturing team members to understand which missing details caused the most confusion later. Based on that feedback, I created a short review checklist covering items such as critical dimensions, tolerances, material specifications, surface requirements, drawing references, and manufacturing notes. I kept the checklist simple because I wanted engineers to use it consistently. Before submitting my own drawings, I started using the checklist and asked another engineer to try it as well. We discussed items that were unclear and adjusted the wording. I also suggested that engineers complete this quick check before requesting a formal design review. The goal was not to replace engineering judgment. It was to catch routine omissions earlier so reviewers could spend more time on important technical decisions.

Result

The drawing review process became smoother because fewer routine issues were discovered during formal review. Engineers had clearer expectations about what a drawing should contain before submission, and reviewers could focus more on design quality and manufacturability. I learned that a useful process improvement does not need to be complicated. A simple change can work well when it addresses a repeated problem, is easy for people to follow, and is improved with feedback from the people who use it.

Why Interviewers Ask This

Interviewers ask this question to understand whether a candidate notices inefficient engineering work and takes practical ownership of improving it. A strong answer shows problem solving, process thinking, collaboration, sound engineering judgment, and the ability to make a change that other people can realistically use.

Interviewer may ask next
How did you decide what to include in the drawing review checklist?

I based it on repeated comments from recent drawing reviews and feedback from engineers and manufacturing team members. I focused on items that were commonly missed and that could be checked before formal review. I also kept the list short so it would support the process instead of becoming another administrative task.

What would you do differently if you improved this process again?

I would involve a small group of reviewers earlier and compare their feedback before introducing the checklist more broadly. That would help confirm that the checklist covers the most important recurring issues while staying simple. I would also review it periodically so outdated items could be removed and new recurring problems could be added.
