You can ask for verifications of course. You can get copies of the degrees, access any GitHub account the applicant provides, call to former employers they provided as recommendations. If applicant refuses to do that, well, I suppose you can use that factoid in the hiring decision too. Just ask for permission to google if it's crucial for the process.
