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.
