Their email said “The next stage of the process is our interactive assessment, which is sent only to candidates who are successful at the initial screening stage. These will be issued in phases, so please don’t be discouraged if you know someone who has progressed and you haven’t heard from us yet - we may simply not have reached your application. A link will come to you via "Amberjack Assessment Platform", if you are progressed.” So I guess it means next stage! I just got my email progressing me to test too yayyy
