Yup, can be done. All we need is just to call up the university records dept to verify for us, based on the info sent by applicants. That's for simple verification.
For a more thorough one, usually we email (from company's email address) to request from the university a full report.

So yeah, if you fake your CV or certs... you're gonna be blacklisted. & if you don't turn up for interviews, it'll be stored in our databases. Some uni graduates are notorious, so we straightaway blacklist them.

Sometimes we share the blacklist among ourselves, esp. if the company has subsidiaries or branch offices, or if we're in the same industry. So, don't think that bosses/HR don't know each other. If you apply the job via job search websites, we can secretly rate you as well. Other employers can see the ratings, but not jobseekers themselves. That's why jobseekers apply for so many jobs but no employer is interested in hiring them... coz the jobseeker's rating is poor.

Yeah, that's why some jobseekers find it hard to get jobs... coz of their own wrongdoings (didn't turn up for interview/ very rude/ fake info/ job hop too frequently etc). Don't assume employers are stupid. There are many ways to dig out info and throw away those rotten apples, and save other employers from headache.

So, don't take the risk and spoil your own rice bowl.
