Hi guys, I'm a longtime lurker but it is just my third contribution. I know this is more of a guide than anything else, but it's free and we chose to release it without gatekeeping: no email signups or registration required. This is an extensive guide for anyone who is hiring for the data scientist. Everything you ever wanted to know about identifying, screening, and hiring exceptional data scientists comes packed in this handy guide. I joined HackerEarth after our startup Preadr (an AI-based content suggestion platform).
