If you’re a developer (or any other kind of tech professional), you know you have the skills to succeed in a crowded, constantly changing marketplace. But what’s the best way to show off those skills to prospective employers?

HackerEarth’s latest State of the Developer Ecosystem report, drawn from “thousands” of responses from developers, hiring managers, and tech recruiters, asked developers how they showcased their skills—and it turns out that social media is a preferred channel for doing so. Check out the chart:

There’s no right way to show off your skills. Some developers are more comfortable with demonstrating their expertise via the social media channels of their choice, but others might prefer contributing to open-source projects or spinning up a blog in which they break down how they built an app. Whenever you’re applying for a new job, make a point of including any links to social-media handles, GitHub repos, and the like on your application—you want recruiters and hiring managers to realize how much you know.

From an organization standpoint, some 38.5 percent of recruiters told HackerEarth they gauge candidates’ skills on their open-source contributions, while 31.1 percent said they took hackathon victories into account; much smaller percentages looked at social media and blogging. With that in mind, if you’re just starting out in your tech career and curious about the best ways to show off your skills, consider participating in open-source projects and signing up for hackathons—those are clearly channels that companies hold in high regard when it comes to analyzing a candidate’s skills.

If you can demonstrate that you’re supremely skilled in a particular programming language, framework, or tool, you may even compel the hiring manager or recruiter to overlook other requirements listed in the job posting, including certifications and formal degrees. To achieve that, however, you’ll need to have a substantial body of coding work—and pass a series of technical interviews.
