More jobs for C programmers?

I am a university student and I must admit that C is the only tool that got me a job. All other opportunities required me to do leet code and multiple rounds of interview which did not materialize to an offer. And now I am finding more and more jobs advertising C / C++ expertise and significantly more response rates form employers.
Are there any changes happening in the world of C? I am more confused as Rust is the newest with lots of hype and somehow rarer job postings ?! Does it have something to do with programmers in general?
