Hello there! 👋

Tech interviews are harder than ever and even senior developers struggle answering tough questions during the process.

Yup - interviewing for a tech job is intimidating and time-consuming, and passing the technical interview is more difficult than ever. Tech companies are using methods that do not necessarily find the best developers but those that are best prepared for the interview.

Most candidates have two challenges with the interviews:
1 - They know how to code but not the theory.
2 - They don't know how to prepare for the interview.

That’s why I've written Slay the JavaScript Interview - to give all developers the chance to ace technical interviews without losing months of trial and error. Each page is packed with a sentence or two that gives you the absolute clearest explanation of the concepts possible. Some questions are followed with a short code example, while others are reinforced with a link to my favorite books and articles.

In just a few weeks after lunch, the book became the #1 pre-release on Amazon and helped tons of developers(like you) get new jobs. I’d love for you to give it a try.
