I applied online. I interviewed at BT Group (Ipswich, Inglaterra) in Feb 2017
Interview
Online application, strengths based online test, HR interview with recruitment company, technical phone interview and finally, an assessment centre (incl. technical interview, presentation, group activity, HR interview) . The initial HR interview was pointless and more of a screener, whilst the technical phone interview was more a knowledge based test, rather than coding.
Was asked why I wanted to join the role standard questions then moved onto a technical Q&A where I was asked about Python specifically and different programming languages that I knew.
