Quite a popular thing these days, but do you trust them!. Speaking to a pal who works at a big company. He told me half of their on-line applications are received with details missing due to the companies computers having funny five minutes. Now as an experiment, I picked a random job on a nameless councils website. I just filled in my name, address. The online application gave me a password & user ID to go back if I wanted to finish the application later. I typed the login deatils again and hey presto, login error, no application found!!.
