I applied online. The process took 1 week. I interviewed at REI Systems (Arlington, VA) in May 2018
Interview
There was phone interview for an hour and then 3 hour face to face interview. HR is very quick and fast so if you crack phone interview, you will soon get request for face to face interview
Interview questions [1]
Question 1
Mostly everything written on your resume. Be prepared to elaborate every word on resume
