I applied online. The process took 3 weeks. I interviewed at RTTS (New York, NY) in Jul 2019
Interview
Responded about a month after I sent in an online application. The whole interview process took about 2 weeks from phone interview to 2nd in-person interview with the founder. The phone interview was basic coding questions as well as general programming knowledge. The 1st in-person interview had a short 30 min quiz. Mostly on coding syntax (C++ and SQL) with logic questions at the end. Final Interview was heavily focused on your knowledge of the company. the final response was within a week of the final interview.
