Books of career advice can’t be exactly about your situation. As the author, I don’t know anything about you. I don’t know your job situation, your history, your background, the type of job you’re looking for, or what is important to you in life.
Don’t blindly follow the directions in a book.
You’ll have to adjust some advice to your given situation or your given location. If you live outside the United States, some advice may not apply. In some European countries, it’s standard to include a photo with a résumé, where in the United States it’s likely to get your résumé thrown away. Even within the United States, behavior at an interview in the Bay Area is likely to be very different from at a company in Chicago.
