I have been happily working in telecom for ~3 years now developing in C and I actually got the job without any prior experience. However, prior to working there I did my Master thesis at the company, which enabled me to show commitment and learn a lot about their product. As you might have realized, this also makes me quite new to the job market, so take my advice with a grain of salt for these reasons. Furthermore, I can't guarantee telecom is a good place to look for C work. We are the only section of our company with a purely C codebase from what I know. But I still wanted to comment and suggest that Low level Networking might be a good option to look at. A good search term might be places that use DPDK.
