I had an informal/screening interview with the Product Manager, which lasted about 20 minutes and was just a very general chat about my CV. I then had a 1 hour interview with the Product Manager and Line Manager, which was also focussed on my experience/CV. I was asked to talk through my experience in more detail. I was then e-mailed a test, which was focussed on typical tasks you do when working in an implementation role. I then had a 30-40 minute informal chat with the managing director of the product/division I was going to be working for (not the managing director of Sage). This was not as scary as it sounds, and was very much a friendly, general chat about experience, hobbies etc. And all in all, a pleasant experience. The entire interview was done online, due to COVID 19. Not London (the glassdoor system has no online option)
