    Application Details

    The process took a day - interviewed at Northrop Grumman in December 2007.

    Interview Details

    I spoke to at least 3 different groups of people. Some were one-on-one and some were two-on-one. This interview was not behavioral. It was purely technical. They asked a lot about signal processing mathematics like: Laplace, Fourier, and convolutions. They had a board and markers for me to show my work in one case.

    Interview Questions
    • He drew 2 graphs on the board and asked me to draw the graph of the convolution of the two graphs he drew.   View Answer

    Application Details

    I applied through college or university. The process took 3 days - interviewed at Northrop Grumman in February 2008.

    Interview Details

    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
