This is not entirely true when securing your next career move, but it can play a significant part in getting the interview which leads to it. A professional recommendation can go a long way to ensuring that you get to meet your potential new employers in person. A professional recruitment firm will not only ensure the best candidates get their chance to shine, but are also thoroughly prepared and receive valuable feedback throughout the interview process. A Professional Recruiter can optimise your chances of 'getting through the door' and reduce the 'wait and see' lottery of applying direct. They can act on your behalf for any vacancy and give you an ally where it really counts.
Many candidates think of the interview as merely an evaluation of their technical abilities.
In reality it is much more. An interview is not a semi-passive conversation during which you answer questions and then wait to see if you receive a job offer. It is a sales process that requires preparation. Remember that you are selling yourself, and this is the time to close. If it is the first interview, then ask to attend the second interview.
