    Average Interview

    Application

    I applied through college or university. I interviewed at ADTRAN.

    Interview

    College student interviewing for entry-level position. 8 hour interview process, cycled through about 10 different groups/managers. Each interview was different in terms of length (20 min - 1 hr), number of interviewers (1 - 7), type of questions, etc. Some focused solely on soft skills, some solely on technical questions, some were a mix. No breaks except for lunch which was also an interview.

    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 2+ months. I interviewed at ADTRAN (Huntsville, AL).

    Interview

    Talked to them at a Career fair and had an interview with them the next day. They asked standard questions about my education and questions about what polymorphism is ect. Not a casual interview, but also not high stress.

    They invited me back for a second interview in Huntsville. This was an all day thing. It took about 6 hours of interviewing with a lot of different people. This interview was a lot more stressful. I was asked multiple times to do coding either on a white board or on paper. The questions are not easy, but they work with you to help you if you need it. Also, I lost some points because I didn't do a lot of research about the company and its competitors before, and they asked me about it. Have some technical examples to prove why they want you. They care more about your skills than anything else, and they do quiz you to see if they think you can cut it.

    Interview Questions

    • Bit coding for clock cycles, finding the 5 closest points to another point from a file of points, tell me about the research you have done on the company(competitors ect.), we noticed in the last interview you were lacking in (insert area here) what have you don't since then to rectify this if anything, how have your other interviews been going if you have had any   Answer Question

    Interview

    First is phone interview. Most are general questions about your experience, and some technique questions. Not very hard. Then go to an onsite interview. It took all day from 10 am to 6 pm. You will talk with more than 10 interviewers about questions about C++, algorithms. But they will serve you a nice lunch.

    Difficult Interview

    Application

    I applied through college or university. The process took 5 weeks. I interviewed at ADTRAN.

    Interview

    Some company representatives came to a university career fair, where the first non-technical interview took place the day after the career fair. Then within about a week I was contacted by a recruiter to go and interview on the ADTRAN campus (which is absolutely lovely, by the way). They provided hotel accomodations for the night before at the Best Western hotel which is about 15 minutes away (driving) from their location. The interview day consisted of approximately 30 minute interviews from 10:30 AM to 4:45 PM. During each time slot, I was interviewed by 1 or 2 people. Interview types varied but, in general, there were technical interviews and non-technical interviews. The technical interviews consisted of writing code ranging from reversing a string to bit manipulations to questions about polymorphism and object-oriented programming. There were also some OS questions thrown in (i.e. deadlock causes and prevention, mutexes and semaphores, etc.) The non-technical interviews involved questions about previous experience, items on my resume, and "What would you do in this situation?" type questions. Overall the day was a bit exhausting and a bit repetitive for the non-technical stuff, but it was definitely fun.

    • Question difficulty varied; none stick out as "most difficult" or "unexpected".   Answer Question

    Neutral Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at ADTRAN (Huntsville, AL) in October 2014.

    Interview

    It is extensive: we started at 8:45 in the morning, and I was taken from room to room to interview with multiple groups of people. The first and last room consisted of managers for behavioral interviews, and two groups in between conducted technical interviews. The behavioral interviews are manageable, but the technical interviews were fairly difficult for me (which is likely why I did not get an offer). In the middle of all of this, I was treated to lunch where I was interviewed one-on-one by a higher-ranking manager. The interview process ended around 1pm.
