Software Engineer Interview

Average Interview

Application

I applied online. The process took 4 weeks. I interviewed at L-3 Communications (San Diego, CA).

Interview

Phone screen with some behavioral questions, and a memorable question about how would you fix a problem - because it had an answer the interview was specifically looking for.

Communication over email was pleasant leading up to the onsight interview. I didn't have to wait very long to be taken to HR which was nice.

Felt some hostility when talking to HR about salary before interviews which put me in a nervous position. I had just driven 2 hours and felt like they were ready to kick me out just because I said I didn't want to talk about my current salary.

I was then interviewed by several engineers who asked repetitive questions - I think I was drilled on virtual functions by 3 different interviewers. One interviewer made me sweat on a whiteboard while they were on their phone. I had to wait 25+ min in a room for one of the interviewers. I had a good experience with two of the more laid back engineers who weren't looking for specific answers to questions, it felt more of a conversation and I would have enjoyed working with them.

    Application

    I applied through an employee referral. The process took 3 weeks. I interviewed at L-3 Communications (Salt Lake City, UT).

    Interview

    I was contacted by email by the hiring manager to set up a phone interview. In the phone interview there was a group of three or four engineers who asked me basic networking and software engineering questions. (Explain the difference between TCP and UDP, why is object-oriented design used, talk about how you play nice in the sandbox at work.) It took a week for them to get back to me about an on-site interview. At the on-site interview, I gave a 15-minute PowerPoint presentation and talked to several hiring managers and lead engineers.

    Interview Questions

    • 1) Explain the difference between TCP and UDP. When would each be appropriate.
      2) Given a network sketched out on the whiteboard, explain how a packet gets from one host to another in as much detail as possible.
      3) Tell us what you know about OSPF, ARP, Ethernet, and TCP protocols.

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at L-3 Communications (Camden, NJ) in October 2015.

    Interview

    Got a call from HR about a week after meeting them at a campus career fair. They wanted to set up an on-site interview at a time of my convenience. We set it up about a week after I got the call. Had an engineering panel interview (with HR, PM, and software engineer) and afterwards, lunch with the director of software engineering. Both meetings were very discussion-based. Not really any "technical" questions besides asking about the technical things I listed on my resume.

    Application

    I applied through college or university. The process took 1 day. I interviewed at L-3 Communications (Lubbock, TX) in September 2015.

    Interview

    I went to a first interview that resulted from talking to them at my college's job fair. So in my case, the day after the job fair I went in for a 30 minutes interview one-on-one with a software project lead.

    The interviewer had a generic form of questions he was required to ask and fill out first. Some programming background questions and a few behavioral. Nothing to unusual.

    After that, the interview turned into a more open format. They did allow for me to ask questions, but in my case the interviewer spent the remaining time getting a better feel of my experience and strengths than just answering my questions.

    It was a pretty simple interview. I assume that there is likely a second round of interviews on site and last longer.

    Interview Questions

    • They asked whether I had an experience with databases and object-oriented programming and what languages I was proficient in.   Answer Question
    • For behavioral, I had questions such as give a situation and how I managed to resolve issues within a group.   Answer Question
