I only know Gayle from reading her answers on Quora, and I'm not easily impressed by people's reputations, but having looked through this book it's very clear that she knows exactly what she is talking about.
I used to work in the technology industry and had a successful career - successful enough that I retired aged 35. Gayle's advice is the kind of information I would have liked to have known when I started, rather than learning by trial and error.
The book is perhaps particularly useful if you are just starting your career (or even still in education - there's a a useful section on 'Advanced Positioning and Preparation')
As you might expect, the bulk of the book is about actually getting that dream job, i.e.:
- Resumes.
- Cover Letters.
- References.
- Interview Prep.
- Refining your personal brand/pitch.
- Behavioural Questions.
- Problem Solving.
- Interviews.
There are also sections on specific 'dream' employers (Google, Apple, start ups, gaming companies, etc)
I'm not really qualified to comment on the chapter on Women in Tech, but as Gayle says, it's not only women who suffer from the “imposter syndrome” that holds many talented people back from the success they deserve, and it certainly seemed like practical advice.
Finally there are a couple of chapters on managing your career and leveraging your current position to work your way up.
The book is written in a clear and engaging style with lots of bullet points, action items and short examples. There are useful real world questions and answers at the end of each chapter, that help to tie the theory and practice together. What it isn't, thankfully, is padded with 'humorous' cartoons, digressions and war stories.
Cracking the Tech Career won't guarantee you that dream job, no book of career advice can, that's your responsibility, but all my life I've found that learning from other people's mistakes and cutting out the schoolboy errors puts me ahead of 90% of people. Who doesn't want to jump straight into the top 10%?
Overall, a solid book, packed with practical advice. I recommend it, particularly to those just starting their career.
