For those that are in school (college/university), use your career counselors. My pit fall was that I didn't use them as much as I should have. I was super fortunate to know a very good friend who ended becoming a career counselor at a major university. They have all the tools and knowledge to help you, use them because the reason most take that job is because they are actually very nice people and love to help others!
For everything I learned in school, I think a full semester is required to learn about the resume building/interviewing/hiring process. This isn't easy stuff, everyone needs practice in this process.
And if you aren't in school, go to your local community college, they have career counselors there who can help aswell. They might not have the exact answers for you, but they will help you find where to get those answers.
Just kind of wish someone yelled this information at me 5 years ago lol.
