I applied for the job and received an email for a phone interview one week after applying. The phone interview was with an engineer. It covered topics from my resume, including:

• Receiver and transmitter basics
• Key parameters of LNA (Low Noise Amplifier) and PA (Power Amplifier), with explanations
• Reasons for using an LNA
• Importance of being at the Intermediate Frequency (IF)
• Mixers and antennas.

She also asked about the lab test equipment I had used.

I passed the phone interview and had the on-site interview with five managers and my recruiter. The most important topics you MUST know are the Smith chart, IP3 (Third-Order Intercept Point), and PLL (Phase-Locked Loop). They all asked questions about these, as well as about filters and SAW/BAW (Surface Acoustic Wave/Bulk Acoustic Wave) technology. You should also be able to discuss the projects mentioned on your resume.

I didn't receive an offer because I wasn't fully prepared for the interview, but I learned a lot.

Directions to give design engineers:

Where to put each component (filters, mixers, LNA, etc.) of the transceiver, and why.

What kind of filter to use, and why.
