I've just had this email:
Thank you for contacting us.
we have launched a new campaign now and do expect to have all finalised locations signed off by early March.
Once we get the finalised plan from Openreach we will start planning out where and when our first set of Assessment Centres will take place.
Please bear with us as we do have huge number of candidates on file and we cannot guarantee to call up everyone to Assessment Centre immediately – it does very much depend on where our new vacancies will be and which locations are Openreach priority to fill first.
Openreach Recruitment team
So location priority initially.
