You should say:
when the team was formed
who else participated in it
what you did there
and explain why you became part of the team.
I was an enthusiastic member of the student union while I was at university. My university was founded in 1950 and the union had existed for many years, but obviously there was a turnover of members as students graduated.
Besides myself, the union consisted of a number of my fellow classmates and some students from other departments. It was nice to mingle with people outside of my department and make friends in different circles. Despite this, I was especially glad that my good friend Tina was also an active member, so we could chat and see each other without our union commitments getting in the way.
The role of the union was to organize student events, for instance the end of year party or certain competitions like the annual drama contest. The biggest occasion I had a hand in was the university’s 50th Anniversary, where we threw an elaborate party, with dancers and fireworks and even some VIP guest speakers.
At first, I had little to no interest in joining the union, but prospect of seeing Tina more regularly was a real incentive for me, not to mention I thought it would look good on my résumé in the future. It turned out to be a great choice as everyone welcomed me with open arms and I made friends that I plan to keep in contact with for the rest of my life.
