    Software Engineer Interview

    Negative Experience
    Difficult Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at OPNET (Bethesda, MD).

    Interview

    My OPNET interview process came in five steps:

    1. 15-30 minute get-to-know-you phone call with an HR person
    2. 60 minute technical phone call with a engineer
    3. Timed at-home coding test
    4. 60 minute technical phone call to review the results with a more senior engineer
    5. Full 8 hour day spent at their Bethesda office. This included demos of their products, two more code tests, two more test-review sessions, more get-to-know-you interviews with mid to upper level staff, free lunch.

    This might seem overly thorough, but it makes more sense than a 5 minute phone call and a two hour technical interview. When they decide to hire a candidate they want to be 100% sure he or she is the right fit.

    All code tests were timed and focused on OO concepts and algorithms. All of them were done in notepad with no IDE, no compiling and thus no need to be syntactically correct. The most important part was the follow up conversation when you get a chance to explain your solution and thought process.

    During the process I was surprised by OPNET's emphasis on academic pedigree. Several people I spoke to pointed out how the founders of the company went to MIT, and that many of them also went to impressive ivy league schools like Yale and Stanford. I was further surprised when they asked my college GPA. After ten years out of school I don't see how that information relevant (and I could barely remember). I too went to an impressive ivy league school and I can tell you first hand that it really doesn't mean much. If you're smart then you're smart and that's about it. Some of the brightest engineers I know are self-taught and went to what some might consider "unimpressive" schools. However I understand why this would be used to filter out candidates. As far as the engineers go, some were extremely serious and others were more casual and friendly, but everyone was certainly smart, passionate and excited about their work.

    I was told in the beginning that if I made it to the full day session they would know right away whether they'd like to extend an offer. Three weeks later and I have yet to hear back. I've emailed my original HR contact several times and she keeps brushing me off. I am taking this as a "no", but I think if a candidate took this much time out of their schedule (including using a full vacation day) then OPNET should have the professional courtesy to give a prompt response, whether its yes or no, plus some shred of feedback.

    Difficult Interview

    Application

    I applied through college or university. The process took 4+ weeks. I interviewed at OPNET (Bethesda, MD) in March 2012.

    Interview

    Applied online. Received a pre-screening interview than set up a phone technical interview. Was asked basic networking and coding questions. Then took a one-hour coding test in which I had to design a system to accept planes that are ready for take off and allow one at a time to take off based on priority. I did this with four different queues, each having a different priority. Reviewed this with a senior engineer. Asked performance questions, how I could have improved it, how I would have used a different data structure. Waiting for next step.

    Application

    The process took 3 days. I interviewed at OPNET (Bethesda, MD) in May 2011.

    Interview

    The process consisted of screening, coding problem and a code review

    1) Screening round was a telephonic interview by senior developer who asked questions on Networking and Java.

    2) Next was coding round in which, the recruiter gave 2hrs time limit and gave 3 coding problem.

    First 2 problems were pretty basic. The third one was little time consuming. It was a simple OO problem of queueing based on priority.
