Based on the HN rules, you can't submit a book as a "Show HN", so this is my version of a Show HN, Book Edition.
I've just published the 1.0 version of my book on hiring data scientists and machine learning engineers. There is a ton of material online for people that want to try to get hired as a data scientist or MLE, but very little on how to hire for those roles. Having built and led data science and ML teams at a couple different companies and getting asked by lots of other people about how to hire for these roles at their own companies, I decided to write a book on the subject as my pandemic project.
I first came across data science more than ten years ago on HN and that led me to pivot into a whole new career. So this is sort of a snapshot after nearly a decade working in the industry. The link at the top of this post is for a 50% discount for people coming from HN.
The permanent address for the book is dshiring.com
I'm happy to answer any questions about hiring for these roles (or about writing the book and self publishing).
