I applied through a campus event. The process was as follows:
1) On-campus interview:
Basic questions related to details on resume, what do you want to do, what are your interests, do you have any questions for us etc. Total interview time: 40 min.
2) On-site interview:
The on-site interview was a month after the first interview. It was a two-day event - interviews on the second day, and a welcome reception event on the first day. This event is where you get a chance to interact with other candidates and Hughes employees, and a chance to discuss and learn about the company, available roles, growth opportunities etc. Event duration: ~2hrs.
The actual interviews took place on the next day. There were four one-on-one interviews with four different interviewers, each lasting roughly 45 min with no scheduled breaks in between. We reached the company campus in the morning, and attended a quick briefing session over breakfast. Next, our names were called out and we were paired up with our first interviewers who walked us to the interview room. Since the campus has a lot of identical buildings and it is easy to get lost given the tension, it is advisable to note the extensions of the HR team and their names for emergencies.
Details of the individual interviews are as follows:
a) First interview: Questions about current research, projects on resume, digital signal processing, digital modulation techniques, simple C programs.
b) Second interview: Questions related to resume, why I quit my previous job, fabrication practices and material selection guidelines followed for projects on resume.
c) Third interview: Design questions from a certain project on resume, interviewer was interested in a lot of design parameters and their values.
d) Fourth interview: Questions from RF & microwave engineering, antenna measurements, Smith chart and impedance matching, questions related to current research.
