Actually when a recruitment firm says its "company confidential" that means the job is not real. Usually serious recruitment firms with real jobs will dislose the name of company once you say you are interested (assuming they got your resume) If they do not disclose to you then it is very high chance that it is only a puller-ads. This is so that they can "pull" candidates in for a number of reasons. Some of the reasons including 1) traning the recruitment newbies to interview people (aka test rat i.e. the newbie will get to do real life interview with you for a job that does not exist to boost confidence and skill of newbie so that they can do a proper interview if they have a real job) 2. So that they can update their database with your particulars, just in case there are future employers who are interested in your set of skills. 3) To have a ready pool of candidates so that when they go "pitch" for jobs with an employer, they can boast and say that they have x no. of people who are within what the employers are looking for.

What a load of bulls*1t. At the end of the day whether its you (as an individual) or others, its all about making money (i.e. yr commission). If that particular candidate has the skills to match what yr client (employer) wants, i think all the agencies will send the candidates CV irregardless, in hopes that the candidate will turn up and accept the offer. After all everbody only thinks about yr commission, screw the reputation
