Phone interview screen, then 3 rounds of interviews that were a mix of behavioral and technical. Technical being like common interview brain teasers or business case scenarios. Interviews did not having and whiteboard coding in SQL or python.

The first round was great and get into the second round case interview. The interviewer gave the positive feedback but got rejected two weeks later. Have no idea what happened. If you are in that interview, remember to ask numbers before construct the frame work
