Sometimes, candidates aren’t totally honest with you despite having very high score on their coding tests. It’s not until the hiring manager meets the candidates on-site that they find out the candidates are not familiar with the required skills.
Filtered authenticates candidates using Linkedin, Github, Bitbucket, or Gitlab (and optionally Facebook). Linkedin is the most used professional profile platform in the United States. Github, Bitbucket, and Gitlab are the most common platforms that developers use for programming work and open source contributions. For experienced developers, they usually have many public or private repositories that live inside Github. When a candidate submits their interview, they must connect one of these social media accounts. The hiring manager will be able to view the candidate's connected account.
Through this authentication process, you can make sure the candidate taking the interview is really your candidate. Occasionally, candidates create a new Linkedin profile just to submit and then delete it afterward (similarly, they may use an empty Github for the authentication). In both cases, we include the report inside your Confidence Analysis and let the you make judgement call.
