Interviewed Feb 2008 (took 3 days)
I got the interview through the university career fair. At first, I had an on campus interview with was mostly behavioral questions. After that I waited two months to be contacted by Northrop Grumman's HR to schedule an on-site interview which spanned three days. They offered flight tickets and hotel together with ice breaking dinner, on-site tour and finally multiple technical interviews. It was a pleasant and welcoming experience.
On site Interview:
1st Day:
Flying to the LA and the HR had a van to pick up the candidates to gather at the hotel. They drove us via tour buses and had a nice dinner in Manhattan Beach with managers and other candidates getting to knowing each other.
2nd Day:
On site tour to several locations including meeting different engineering teams to discuss what they were developing and designing. Then there was a huge dinner banquet in the hotel where I was assigned to the tables according to the hiring team engineers and managers. It was a dinner where we got to communicate with different managers and engineers to know more about the specific tasks and what people they need in the particular groups I was going to interview with the next day.
3rd Day:
This was the last day of the interview process where we were given several tour buses that drove us for the on site interview early in the morning. NGC scheduled everybody to interview at different time slots. I was scheduled to three different interviews which was the digital comm group, and two different RF groups. All three of the interviews had one to two people. The questions involved team work, basic RF knowledge, describing the projects I had done and also digital signal processing.
All three departments suggested I should go for the Digital comm system, because I had shown great interest. Some of the technical questions are:
- DSP knowledge
- Nyquist rate
- What's the sampling frequency
- What's the digital frequency
- Find the aliasing frequency
- Find the Folding Frequency
- Direct form I and II
- IIR and FIR filter. Write out the difference equations
- J-K Flip Flop in DSP
- What's the multiplication of two sinc functions in time domain so what's the frequency response?
- QAM

Interviewed Feb 2010 (took a day)
Submitted application with Resume on line and was contacted by an HR Representative to schedule an interview. My experience with the HR Rep was horrible. They did not return my phone calls in a timely mannor and were unclear with some of the requirements. When I came in for my interview, I had to wait for 20 minutes before I was seen. I interviewed with 4 people total, each person for half an hour.

Interviewed Apr 2012 in McLean, VA (took 2 months)
I applied via an external website and got contacted by a recruiter via email 2 days later. The recruiter was very sweet. She asked for more information in the email, which I provided. About a month later, the recruiter called me to see whether I was still interested and so an on-site interview was scheduled. The on-site interview was scheduled for 2 weeks later. The interview was a panel interview, 4 interviews with 2 managers at a time. It was mostly a behavioral interview. Less than a week later, I heard back from the recruiter that an offer could not be extended. Overall, a positive experience. I didn't know how competitive the PDP Program was but to even get an interview is an accomplishment.

Interviewed Feb 2010 in El Segundo, CA (took a day)
Received email from HR to respond to email if interested in job. I did not actually apply to the job. I had spoken with an hiring manager at a career fair and believe through his referral, I was able to get an interview in the functional area that I wanted. However, I was disappointed that HR did not call me to schedule an interview but rather sent an email. I could have missed the email.
After interview was scheduled, I was told that 2 people would interview me (senior manager and junior employee). When I arrived for the interview, only the junior employee interviewed me. I was told that the senior manager was otherwise engaged in more urgent matters.
The interview was okay. Some questions were more challenging than others and I didn't adequately prepare to answer certain questions. After the interview, I contacted HR to know a brief time line of when I can expect to hear an answer. HR pushed me off for 2 weeks or so and I never heard back.
