I applied through a recruiter. The process took 1+ week. I interviewed at High Speed Two (Birmingham, England) in Jul 2018
Interview
Met with potential line manager and one other manager.
Did not hear anything for 3 weeks so I called the agency an they informed me I would get a call from one the interviewers - I had a text asking what is a good time to call to which I replied and have heard nothing since - 2 weeks ago - extremely disappointed with the lack of basic professionalism.
