The process took 2 weeks. I interviewed at Blink Health (New York, NY) in Jan 2019
Interview
Pretty standard: coderpad, then home assignment, then on site rounds (dev, architecture, and cultural). Overall had a great experience: the coderpad was fun and visual and easy, dev round was just reviewing code for the home assignment
Interview questions [1]
Question 1
coderpad was to implement a directory tree visualizer
dev round was to just review the code for the home assignment
architecture round: "how would you build slack"
