I applied online. The process took 2 months. I interviewed at L3Harris (Salt Lake City, UT)
Interview
The interview process was more about what is expected of you should they offer you a position which includes being moved to a location that 99% of the time will not be in Utah and that will require approx. 160 days deployed overseas a year, there are some exceptions but not many.
Interview questions [1]
Question 1
Questions usually revolve around networking and RF capabilities which is most likely what got you there to begin with as that is what they look for. However, if you know someone that is currently an FSR and willing to vouch for you that speaks highly.
