RF & Wireless interview questions

Signals that radiate, and the compliance problems that follow.

Interviewers rarely ask you to define anything here. They describe a symptom, a measurement, or a constraint and watch how you reason. The 4 concepts below are what a strong answer draws on, and they are exactly what this product weights up when a job posting mentions rf, wireless, antenna.

What interviewers probe

Impedance Matching
Matching networks, VSWR, and what a mismatch costs.
Antenna Fundamentals
Radiation, ground plane dependence, and placement constraints.
EMI / EMC
Emission sources, susceptibility, and designing for a compliance test.
Link Budget
Path loss, sensitivity, and margin in a real deployment.

Understand these first

These sit underneath rf & wireless and come from other topics. If this material keeps failing to stick, the gap is usually here rather than in the topic itself.

How this topic gets weighted

A posting that mentions rf, wireless, antenna pushes rf & wireless up the curriculum, and the weighting is shown with the quote from the posting that caused it. Two candidates preparing for different roles get genuinely different plans from the same taxonomy — and because mastery is stored per concept rather than per application, what you learn here still counts on your next one.
