Interview
HR found my profile in Linked in and called up for a discussion. There was the usual background discussion and very simple sql questions. Then they scheduled a phone screen for a sql and python interview. They gave some prep materials as well. In the phone screen, it was all coding. I had assumed it would be a combination of sql and python but it wasnt. I didnt move past this stage.

Interview
One phone tech screen which covered both SQL and Python questions. They do the best job I've seen of hosting this tech screen / interview. They use CoderPad, and actually let you run the queries / functions. For SQL they provide a nice schema for you to reference. And for coding (python) they provide basic methods and reference materials for you to review if needed.
