Technical Support Engineer Interview

Anonymous Interview Candidate
Birmingham, AL

I applied through college or university and the process took a day - interviewed at ADTRAN in March 2012.

Interview Details – Initial meeting occured at a Job Fair on campus. The paid for my mileage and hotel to drive down and interview. Interview consisted of multiple groups of people for about 1 hour per group and covered a broad range of networking topics. The most interesting was a simulated support call with a network administrator having issues.

Although my networking background was very slim, they seemed to like that I was able to pick up on things and extrapolate. They paid attention to the "intangibles" and not just technical ability. Everyone was very easy to get along with and it was an enjoyable, although long day. Included lunch during the interview and dinner the day before.

Interview Question – Most of the questions were unexpected as my background in networking was very light.   Answer Question

Reason for Declining – Had another job offer in the town I was currently living in.

Very Difficult Interview

Hardware Engineer Interview

Anonymous Employee
Huntsville, AL

I applied online and the process took 2 weeks - interviewed at ADTRAN in October 2013.

Interview Details – The entire process took the better part of a day. I interviewed with about 7 or 8 different groups. The groups went all the way from hardware and PCB layout, to pure software engineering. Most of the interview involved some basic networking questions, behavioral questions and questions about the projects and experience listed on my resume. One or two groups, however, were extremely technical. They had complex C++ code (dealing with polymorphism, and inheritance between classes) and had me give my best efforts to decipher the code. All in all it was a positive experience, and they were nice people. Do your homework for this interview, because it will be a tough, technical interview with a lot of smart people.

Interview Question – What's the difference between Layer 2 and Layer 3 ethernet? Explain the inheritance and relationships between these 3 classes.   Answer Question

Trade Show Manager Interview

Anonymous Employee

I applied through a staffing agency and interviewed at ADTRAN.

Interview Details – Apply for position on-line at www.adtran.com; attach resume and any letters of recommendation. Typically an initial interview is done with an HR representative followed by many interviews with director(s) and marketing VP

Negotiation Details – I negotiated the salary only because I was here as a temp first. I had a permanent job waiting for me involving some red tape and notified my supervisor of the situation. When Adtran offered me the job, I explained the other job was for more money. They came back and matched the offer.
