I applied through a recruiter. I interviewed at Affectiva (Boston, MA) in Feb 2020
Interview
Typical (pre pandemic):
Phone screening;
Technical phone;
All day, in person interview.
In the end, I felt the company asked for much more out of me than it ever came close to returning. There was limited learned about the company or even what the company liked / disliked about my interview/ responses/ etc, while I seemed to always be on the side of explaining and responding, I’ve interviewed many, many times, and this was exceptionally the case (ie I even asked for feedback, and they never responded to email.. which was sort of the trend / vibe I caught the entire time).
Interview questions [3]
Question 1
A lot about PhD research;
1 hour presentation on work;
Several textbook questions on ML (mostly traditional, eg, tree regression, svm, etc.)
I was given a matrix, placed at the top right corner, and asked to get to the bottom right at lowest cost, where each element of the matrix having a value that cost for that step.
