I applied in-person. The process took 2 months. I interviewed at Scotty Labs
Interview
Pre-interview chat on one day with CEO and CTO, then another day with an actual whiteboard coding interview by two engineers followed by another coding interview with the CTO.
Interview questions [1]
Question 1
There was a string concatenation question with a nominal requirement to write working code on the whiteboard, but the real emphasis was on talking through the problem.
