ActiveCampaign Data Scientist interview questions

The process started with a short assessment. One part was technical in nature and focused on programming and data modeling skills; the other part measured creativity and the ability to reason about data in a business context. After the assessment I had a phone interview and an in-person interview with the Director of Data Science. We mostly talked about my past experience and my approach to predictive modeling. There were a few technical questions about machine learning and a couple questions about basic data structures in R (my primary language). After that I had 1-1 interviews with the CTO and with one of the engineers. These were mostly informal discussions and a chance for me to ask questions about the company. The process moved quickly, at time a bit faster than I would have liked. That aside, everyone I interacted with was very respectful and straightforward with me.
