Hi! It is commercial discussing an article however I would say that it is a 50 50 split with competency questions.
The competency questions were not too hard and felt like a conversation. For the commercial element there was not a lot of guidance for me, the Partner just kind of let me talk through it which I thought was nice. However I didn't get the WVS and I'm pretty sure it is because I was not technical enough. So, even if they do let you take the lead on the article make sure you are structured and precise.
It was really friendly and not intimidating to me so I wouldn't panic. Make sure you have some good example competency questions prepared e.g a time where you showed resilience/teamwork etc
