Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Tell me about a time your HFSS or CST simulation didn't match what you measured in the anechoic chamber. What did you do?
rigor in debugging sim-to-hardware discrepancies and honesty about failure
Tell me about a time you had to integrate an antenna with an RFFE team's filters, LNAs, or power amplifiers and something didn't line up on impedance matching. How did you resolve it?
cross-functional collaboration and ownership of link budget issues at the interface
Describe a time you had to explain a technical antenna limitation to a customer who wanted something the physics didn't allow. How did that conversation go?
ability to manage customer expectations honestly under technical constraints
Tell me about a time you contributed to a proposal or business development effort. What was your role and what happened with it?
comfort operating beyond pure engineering, into the business side the posting calls out
Technical
Walk me through a phased array project you led, from element design through beamsteering architecture. What tradeoffs drove the final design?
depth of hands-on phased array leadership versus surface familiarity
How do you approach grating lobes and mutual coupling when you're pushing scan angle range in an array design?
whether the candidate actually understands the underlying phased array theory, not just terminology
How have you used Taylor or Chebyshev weighting to control sidelobes, and what did you give up to get there?
real working knowledge of amplitude tapering tradeoffs, not textbook recall
What's your experience with Cadence for matching network design, and how do you validate that a matching network will hold up across the full band and temperature range?
practical fluency with the specific tool and design robustness thinking
How do you choose between substrates like Rogers, Taconic, or Megtron for a given mmWave design, and what have you seen go wrong when the wrong one was picked?
materials knowledge grounded in real consequences, not just spec sheet familiarity
What's your process for validating a design in a near-field or far-field range, and how do you know when a measurement discrepancy is a test setup problem versus a real design flaw?
hands-on measurement rigor and judgment under ambiguous data
Have you worked with System-in-Package or Antenna-in-Package technologies? Tell me about a specific challenge that came up with one of those integrations.
whether the preferred SiP/AiP experience is real or aspirational
Situational
Say you're designing an antenna for a mmWave application and you're seeing higher than expected path loss and manufacturing tolerance issues. How do you isolate whether it's the antenna, the substrate, or the assembly process?
systematic troubleshooting under mmWave-specific constraints
Imagine a customer changes their requirements mid-program in a way that invalidates your current array design. How do you handle that with your team and with them?
composure and communication skills when scope shifts late
You're juggling a proposal deadline, a customer technical review, and a chamber test that's behind schedule. How do you prioritize?
multitasking and judgment under competing real deadlines typical of this role
