... read the job advert properly.
We are currently looking for more London handymen, and have an ad running in Gumtree (here). The ad specifically asks people to go to our website and complete the application form they will find there. It specifically says not to simply use the form on Gumtree to send in a CV.
At least 50% of the respondants simply send in their CV, it is just unbelievable. I suppose they are just not even reading the ad, it is a bit annoying.
