Applicants for jobs in estate agency are damaging their prospects by their activity on social media.

Recruiter Anthony Hesse, managing director of Property Personnel, said most employers now research candidates online – and that many applicants put themselves out of the running straight away.

Hesse said: “Over 90% of recruiters use social networking sites to screen prospective employees, with 70% admitting they have rejected or hired a candidate based on what they saw about them online.

“It’s no use perfecting your interview technique if your online profile presents a very different picture – and this applies as much to Twitter and Facebook as it does to LinkedIn.”

He advised candidates: “Set your social media profiles to ‘private’ and keep a professional Twitter handle for business.

“If in doubt, Google yourself and see what you come up with!”

Hesse also said that an astonishing number of candidates do not research their potential future employer before interview.

He said: “We’ve even heard of some candidates being asked which of the agency’s half-dozen offices they would like to work in, and they have been unable to name a single branch.”
