I had an Assessment centre today and I kind of messed my group activity up. but my interview and and my Analysis exercise went really well. When it came to the group activity, I did speak but not a lot and I contributed a little bit to the discussion and when it came to presenting the group activity and was my turn to speak I lost my track off thoughts and said " John could you please take over and I will speak once I get my words correct" , I did end up speaking and making a input at the end but the other 3 people in my team were very strong compared to me. But my interview and analysis exercise went really well. Would messing up the group activity ruin my chances of getting the role? This was for Lloyds off London.
