Toptal

Toptal doesn't have the largest work or user database, but that's the point: this site exclusively includes top-tier freelancers. That's why Toptal is trusted by organizations like Microsoft, Bridgestone, and Salesforce to uncover top talent.

To guarantee that only the finest applicants are accessible, Toptal employs a thorough screening procedure that includes language and personality assessments, skills tests, live screening, and test projects. Only 3% of Toptal's freelance applications are chosen for projects, according to the company, and each job is hand-picked by industry specialists.

This is a high barrier to entry, but it implies that freelancers will be able to find lucrative tasks and businesses will be able to locate high-quality employees. Also keep in mind that Toptal exclusively hires developers, designers, financial professionals, and product and project managers.

Because of the narrow job titles and high barrier to entry, there will be many scenarios where Toptal isn't appropriate. This is the place to start if you're a world-class freelancer or need to locate world-class talent.
