I applied online. The process took 4 weeks. I interviewed at Openreach (Warrington, North West England, England) in Sep 2018
Interview
Asymetric video format, very uncomfortable and degrading. 'passed' all steps then no contact at all. Do not recommend. Shame because speaking with their engineers, it sounds like good work, but clearly don't wish to reject people and prefer to ghost.
Simple and easy to apply, kept informed of the progress throughout the process and their open-day and face to face interviews were casual and gave you no stress or worry. The 4 part interview was well thought out and great fun.
