I applied online. The process took 3 weeks. I interviewed at Source Photonics (Los Angeles, CA) in July 2020
Interview
Two rounds of phone screening, followed by a video interview. 45 minutes of presentation, and Q&As. The HR's director is quite nice. The entire time span is relatively long. The audio signal is not very stable during the phone interview.
Interview questions [1]
Question 1
Basic questions about fiber coupling into SMF, factors that can affect coupling effiency.
