I interviewed at Opportunity Insights (Boston, MA)
Interview
Technical case study and interview with director and staff. The case study was on machine learning and other statistics concepts. Brush up on supervised learning, decision trees, logistic regression. It was a great interview though and everyone was really great. If you get the job, you should be very proud!
Two rounds of phone interviews plus a "data" and slide task with a reasonable turnaround. This was a distinct process from the predoc hiring system which involves a different set of tasks and interviews.
