Field Test Engineer Interview Questions
55 field test engineer interview questions shared by candidates
They let me introduce about my studies for few minutes, then asked technical questions such as Bandwidth of LTE? data frame structure? software, tools which I utilized for RF measurement (since I said I have experience)?
All questions were very technical a knowledge based.
What is your previous electrical/mechanical experience
Why do you want to look for a new job? Are you available to business traveling?
The questions weren't even skill-related. They just asked for my availability and if I was okay with working overtime often.
Favorite previous project? Tell me about it. Difficult problem or situation that I overcame? Why was a chosen as leader for my capstone project? Why did you choose Gecko Robotics? solder test - assemble a board in the correct order troubleshooting - what would i do if "this" sensor wasnt working on the robot.... etc etc charts - current line, velocity line, and code runtime line - what is it saying the robot is doing
Testing process: Soldering test - solder a tiny module together in the correct order Troubleshot their robot - had to find and explain troubleshooting process with different problems he gave me (hint.... don't overthink it...) Finally, he drew charts on a white board and I had to explain what the graph was explaining - current, velocity, and code runtime. The interview finished with the mechanical engineer asking me much of the same questions that i had on the phone interview....projects, school, character questions
LTE, OFDM, MIMO, and digital comm basics.
VoLTE call flow, Difference between 3G & LTE, LTE architecture. SRVCC, CSFB, Other telecom related quesiton.
