I am in US and have an undergraduate education in RF. I learnt for LNA, Mixer, Oscillator, Filter, Amplifier, Stubs, Couplers with also Design Labs and Actual impementation of them and testing them using only Network Analyzers not the real world.
What Interview questions I should expect? Mostly I am looking for any trick questions I have never learnt.
If you know your stuff well, you need not worry for tricky question because there is no tricks to play with, it's all work based on knowledge. The employer may not only see how you answer your interview well, but there are other things they will look in to for a prospectus employee, depending on the job description
