It is in our legitimate interests to decide whether to appoint you to a role since it would be beneficial to our business to appoint someone to carry out the role.

We also need to process your personal information to decide whether to enter into a contract with you.

Having received your CV and covering letter and the results from any preliminary test or telephone interview, we will then process that information to decide whether you meet the basic requirements to be shortlisted for the role. If you do, we will decide whether your application is strong enough to invite you for an interview.

If you fail to provide personal information

If you fail to provide information when requested, which is necessary for us to consider your application (such as evidence of qualifications or work history), we will not be able to process your application successfully.
