Recruitment agencies can be ideal for getting jobs within an office environment as many larger companies will only use recruitment agencies to source employees, either as full time staff or for temp work.
The agencies usually have a range of companies on their books and can search through for something that would be appropriate for both parties.

When you first go to a recruitment agency they will usually start with an informal chat and will ask to see your CV. You will then be required to complete one of their application forms so that they can profile match you to a suitable role. As part of this process, particularly if you are going for office work they will usually put you through a series of tests based around your accuracy in recording data, your reading speed, typing speed and spelling and grammar tests. Although this may sound very daunting it’s not something that you have to pass or fail, it merely assesses where you’d be best placed as some secretarial work will come with a set typing speed requirement.

The agency will then put you forward for formal interviews with suitable companies until you find a role that your happy with and start employment with the company directly.
