Tell me about a time you worked with an electrical engineer to solve a problem on a board. How did you split the work?

What the interviewer is looking for

  • This question tests cross-disciplinary collaboration. Works smoothly with electrical, mechanical and test engineers, shares evidence and divides problems sensibly.
  • What to bring out: Shared investigation, clear evidence, respect for each other's expertise, and a solution that might involve both hardware and firmware changes.
  • Expect a follow-up like: How do you get involved earlier in hardware design to avoid such problems?

Another way it may be asked: Maybe a noisy signal or a board that reset randomly. How did the two of you work it out?

A structure to follow: STAR, with the weight on Action and Result

  1. Step 1

    Situation

    One or two sentences: where, when and what was at stake. Pick a real example you were close to.

  2. Step 2

    Task

    What you personally were responsible for. Say "I", not only "we", so the cross-disciplinary collaboration you showed is visible.

  3. Step 3

    Action

    The two or three things you did and why you chose them over the alternatives. This should be about half your answer.

  4. Step 4

    Result

    What changed, in your own measure of it, and what you would do differently. Only use numbers you can stand behind.

This is guidance on shape, not a script. Use your own real experience and facts; never invent details to fill a gap. See the STAR guide and answer frameworks.

Common slips

  • Describing what the team did without saying what you did.
  • Choosing an example with no clear outcome, or one you cannot answer detailed questions about.
  • Ending on the action and skipping the result and what you learned.

How to practise it

Write two bullet points for each STAR letter, then say the answer aloud in about two minutes.
