The interview process was very straightforward. It started with HR recruiting on campus career fair followed by a phone screen a week later. Then I had 4 round of onsite interview. Most of the questions were very straightforward if you know basics of microwave circuits. Some may test your knowledge on microstrip lines and it is very important to know your smith chart. Its a big deal to andswer most questions. Be aware if you don't know a question do random guesses. Answers with your knowledge base and you will be fine.
