A bit on why it’s free now

We recognized that this type of book is a missing resource for many early-career electrical and embedded software engineers. Even through the course of writing this book, we had a few reviewers mention that they got asked, verbatum, some of the questions featured in this guide, and proved to be helpful in their current job hunt.

We’re hoping that by making this resource free, we increase its impact among early career engineers. If you find it helpful, consider telling a friend and/or giving the book a shoutout on your favourite social media.
