EXFO Applications Engineer interview questions

It was a 1 hour interview and two people were there. One was asking technical questions and other one was asking behaviourial question. So the technical part was not very tough but mostly from past experience work and degree done. They strated from very basic questions then take it into real problems. EXFO works for testing and measurment tools equipment for fiber link and network desgining, so most of questions were on OTDR, OSNR, BER, OLTs, DWDM , OSA etc
