One initial phone call with the hiring manager, one technical screen, and one presentation. Technical screen is comprised of asking questions about your resume, and diving into the technical applications (why did you use this model) from a high level perspective. Fairly straightforward questions and was surprised there were no coding questions asked (red flag.) Presentation consisted of creating a simple recommender system and potential use cases and presenting it in a non-technical way. Did not pass this stage as they seemed unsure on requirements. They wanted the approach to not be a kaggle competition, but seemed to want advanced methodologies be used. Experienced Data Scientists are not going to spend more than a few hours on take home assignments, so be wary on how much time you spend on this. The job itself seemed to be employing simplistic solutions as well, so surprised that this was the task given.
