I applied online. The process took 2 weeks. I interviewed at Optum (Boston, MA) in Nov 2017
Interview
1 Campus Interview, 1 On-site interview. Very friendly and informative. No technical interview at all. The campus interview was purely behavioral and really just a screening. The on-site was slightly more technical but no coding question.
Interview questions [1]
Question 1
What are some new technologies you like to work with?
