As hardware engineers, we understand how stressful and struggling the hardware interview process can be. We also suffered the same pain as you might have when desiring to grow further or exploring new opportunities in the hardware industry. Unlike software engineers who are able to find countless online resources such as LeetCode, Stack Overflow, etc., hardware engineers can hardly find their counterparts. The golden information is here and there, but nowhere summarizes it in an organized way that can be easily followed. This series of books is intended to close the gap, by sharing our knowledge, experience and perspective towards digital design interviews. Our goal is for readers to gain real industrial experience by understanding what skills the companies are looking for. The structure of this book is organized in the same way as how the modern ASIC / VLSI industry partitions the workflow. Specifically, in this book, we focus on Physical Design and Silicon Debug , from RTL designers’ perspective. Both are important skill sets that all RTL design engineers should have some basic understanding. In addition, we share a few Behavioral Questions and Useful Interview Tips at the end of this book. We do hope you find the information in this book useful for preparing digital design interviews, and landing a dream job in the industry.
