I'm also looking to get a good job. I think you should contact the employer a few days after you send your CV. And read about the company. Calling them and knowing about what they do will make you seem more motivated and interested. With so many people looking for jobs you need to do something extra to make yourself seen. You have sent your CV hundreds of times, think about how many CVs they receive. Give them a reason to find yours and look at it. Best of luck to you!
