You said you applied to 50 companies. Did you send all of them the same CV?

When I was hiring, there was one thing that made candidates really stand out: when they had previous experience that matched the job description exactly.

For example: I was hiring for a Mac app developer, and I got an application from someone who had developed a Mac app and published it on source forge. That's pretty much an instant hire.

The important part is not hide your relevant experience in a long, generic CV. Once you have a few years of experience, you probably have a lot of stuff in your CV, and most of it is probably irrelevant for the job you are applying to.

So it might be worth it to shorten your CV, and strongly emphasize only the parts that are relevant for the job you are applying to. Don't waste time talking about stuff you did a few years ago when it's not relevant for the job you are applying to.

A concise resume is very appreciated. I normally have a recruiter filtering resumes for me, but when hiring for a data scientist role I went through the list myself. There were almost 400 applicants. I could only spend max. 30 seconds per resume to keep the task manageable. A few candidates bolded key words in their experience section, which made it very easy to scan.
