127 senior rf design engineer interview questions shared by candidates
No specific questions were difficult
Basic RF knowledge based on Smith Chart.
Why do we use a band pass filter at the beginning of heterodyne receiver?
Doherty amplifier theory
Was not sure if there would be technical questions. Got asked some pretty general communication questions.
What is tilt, azimuth? Explain link budget? Explain the effects of RF interference?
RF PCB knowledge
The interviewer asked questions about S-parameters, amplifier fundamentals, Smith chart interpretation, vector network analyzers, and calibration techniques, covering measurement accuracy, impedance matching concepts, and practical RF characterization workflows during discussion.
Give an example of when you had an unexpected problem. How did you approach the problem, what steps did you take to solve the problem, what was the resolution. Describe a time when you went above and beyond expectations. Pretty much behavioral questions.
