We work on an anonymous basis because we are protective; protective of you as the candidate, our client who is essentially funding our work, and our time:
It’s always a worry that a candidate will hear about a job through us, and then choose to apply directly. We tend to have a lot of insight and influence with our client, so this seems bizarre that a candidate would choose to bypass free help getting the job, but it does happen. As this company may not be expecting to deal with their direct applications as thoroughly, yours may get lost.
Secondly, our clients’ information is not ours to disclose, and our clients often dictate what we can and can’t publicise, as they are paying the bill. We do not want to get in trouble with our clients for obvious reasons.
And finally, one of our competitors might see that we are recruiting on behalf of a particular employer, and then contact that company in the hope that they can win their business instead. If they succeed, all of the time we’ve already spent searching for people will amount to nothing which makes us sad.
