The process took 1 week. I interviewed at ADTRAN (Huntsville, AL) in Nov 2007
Interview
Interviewed after several co-op terms. Process and questions were more difficult than I had come to expect, and spoke with a variety of groups both in and out of areas I was familiar with. More low-level hardware/EE stuff than I was prepared for, not that it mattered too much (claimed my ignorance, moved on). Got offer but was lowballed based on my response to questions in HR back-and-forth.
I applied through university. The process took 1 day. I interviewed at ADTRAN (Huntsville, AL) in Apr 2011
Interview
It was my first job interview in my life. I made a lot of mistakes in the interview, but actually the interview questions were not bad. They asked me about my work experience and projects in my resume and some basic programming skills and electrical engineering concepts. One person asked me to write a FIFO code, but I made a stack ( I was too nervous...). Another person asked me about RC circuit. It shouldn't be difficult, if you review some EE materials. I am sure I did not well, but it was a good interview experience as a first job interview. I learned how to prepare for a job interview.
I applied through university. The process took 1 day. I interviewed at ADTRAN (Huntsville, AL) in May 2010
Interview
The interview process started at 8 AM and went until 5 PM the same day. It consisted of meeting with a engineering manager or senior engineer either on a 1:1 basis or 1:2 basis. Questions consisted of technical experience with C++ and embedded systems and personality, situational, and ethical questions. ADTRAN seems to pride itself with hiring engineers with integrity.
Interview questions [2]
Question 1
You have two eggs and a 100 story building. These eggs are identical and possibly much harder than normal eggs. Your goal is to determine the highest floor of the building they can be dropped from without breaking using the fewest test drops.
What is the optimal search algorithm? How many drops would it take using the algorithm in the worst case scenario?
NOTE: Once an egg breaks, it can not be used again for further test drops.
NOTE 2: This is an "inside the box" riddle, no tricks.
