I applied online. I interviewed at Duolingo (Pittsburgh, PA)
Interview
They outsourced interview to Karat, 3 easy technical runtime/logic erros in code questions and then 1 medium to hard LC. Interviewer doesnt help at all and just stares at you
Interview questions [1]
Question 1
What is the runtime of these two algos and which is faster? When might one be faster than the other?
First part of the process was a codesignal assessment; the next part was a virtual interview done through Karat: there were questions about time and space complexity and then a coding question
Interview questions [1]
Question 1
questions about time/space complexity for some code
They respond pretty fast and the recruiter keeps you updated throughout the process. OA is just a basic CodeSignal, then a Karat which can vary but usually asks one LC-style problem plus time complexity questions.
