Hey, I know others on here have already chimed in, but I joined Google not that long ago having been rejected twice before. Please don't sell yourself short. Give us a try.
No disrespect intended, but if you have on your CV that you have "written a book" and it turns out not to be an actual book, with an actual publisher, in actual bookstores, it will create a bad impression with most interviewers. You should rephrase it as an "online tutorial" or something.
Thank you for the advice. I always tend to write a short tutorial, but then people ask, "what made you write the book" or "what's the structure of your book if I want to contribute". That's why I end up writing book. I will keep this tip in mind :-)
I read your tutorial some time ago and found it to be very good, probably one of the best introductions to Go I have read so far. Keep up the good work.
