I have just done an assessment centre how much weight do you think they put on each component; group task, written and partner interview. I think I did good in the group task and really good in the partner interview but I’m not so sure about the written task. Also the partner said I would successful in the legal field no matter the results today
Unfortunately no one will be able to answer this apart from the firm.
Every assessment will be important but sometimes competencies are assessed across assessments. For instance, team working can be assessed in a group exercise and at interview. It maybe that a lower group exercise score for team working could be balanced out by a stronger team working example in an interview.
I would try not to over analyse what might have happened until you get a decision from the firm. If you have been unsuccessful, seek feedback from them to understand where the development areas were.
The partner stating something like that shows you clearly have strengths to leverage in this or future assessments, and so take that as a positive for now.
