There were two onsite interviews at the same day. The first interviewer on the first round asked some general questions, such as introducing yourself. The second interview was technical one. After around one week, I got the offer.

Asked about your antenna projects where director of RF was present. Then a written test on your understanding of antennas. You had to answer 2 of 4 questions about different areas of antenna tech including some questions about current and new technologies like metasurface antenna, application of AI in antenna design.
