I interviewed at OPNET in December 2010.

Interview Details – Was selected for an hour long Campus interview. Then invited onsite for a good full day's worth of interview. I had about 7 rounds of interviews, with 4 rounds going into indepth coding execercises. The last one, however, was a theoretical interview about networking and related concepts. Overall, a tiring, yet, flattering interview experience.

Software Engineer

I applied online and the process took 4+ weeks - interviewed at OPNET.

Interview Details – 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.
