Meta Data Science interview questions

Initial SQL screening case study call - Medium query - Metric level Hard query Another part was a Data Science case study to understand how we think about solving a problem and ability to tie it with business metric

Phone screen with a recruiter, first interview with a data scientist, full loop consisting of 4 interviews, some technical and some business-related. Very mixed experiences, some interviews were fairly easy and others quite difficult. Didn't get an offer, but they came back a couple months later asking me to interview again, didn't have the energy to go through all of that again
