Linear Regression in depth, Data manipulation, Performance Metrics (ROC, AUC, specificity, F1 score,...), explanation of how Random Forests work, how confident I am with Python, R or SAS
First round with the hiring mgr, second round a 3 subround 1 on 1 interview. Tech: Behavioral questions are around 7:3. Process wenrt on steadily but slowly in the meantime.
3 interviews in a row. One hour each and mostly technical questions. Kind of difficult. First about walking through resume and your experiences. Second more technical and hard questions. Last one would be more about salaries and sponsorship.
