Pretty average. Just some questions about experience in data analysis and survey research. Other than that, it is standard interview questions. Did not get the offer though. Talked to two different researchers.
I applied online. I interviewed at SurveyMonkey in Mar 2018
Interview
The interviewer was very nice and made the process very comfortable. However, I was told in the first screening call that most applicants were masters/ phd students and that I might not be competitive enough.
