Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about the analog circuit project you're proudest of from school. What didn't work at first?

What they are checking: Whether they've built and debugged real hardware and can explain what they learned from failures.

Tell me about a time you got stuck on a technical problem. How did you get unstuck?

What they are checking: Whether they know when and how to ask for help, which matters for a new engineer.

What would you do

Your circuit works in simulation but oscillates on the bench. How do you debug it?

What they are checking: Whether they think about layout, parasitics, stability and grounding, which simulations often miss.

A senior engineer reviews your design and finds several issues. How do you respond?

What they are checking: Whether they welcome design reviews as learning rather than taking feedback personally.

About the work

Walk me through how you'd design a low-noise amplifier stage for a sensor signal in a medical instrument.

What they are checking: Whether they can reason through gain, noise, bandwidth and component choices in a practical design.

How would you choose an op-amp for a precision measurement circuit?

What they are checking: Whether they know which specs matter, such as offset, drift, noise and input bias, for a given job.

How does PCB layout affect analog performance?

What they are checking: Whether they understand grounding, routing and separating noisy digital signals from sensitive analog ones.

Explain how you'd design a filter before an analog-to-digital converter.

What they are checking: Whether they understand anti-aliasing and how filter choices affect the signal being measured.

What tools have you used for simulation and lab work, such as SPICE, oscilloscopes and spectrum analyzers?

What they are checking: Whether they have hands-on experience to contribute quickly as a new graduate.

Plexus designs for aerospace, healthcare and industrial customers. How might requirements differ for each?

What they are checking: Whether they think about temperature, reliability and safety requirements that vary by market.

How would you design a circuit so it can be manufactured and tested reliably at volume?

What they are checking: Whether they think beyond one working prototype to tolerances, test points and production.
