Last year, I was heavily involved with a volunteer group in response to the triple hurricanes in the US, and in particular the response to Maria in Puerto Rico. I was a lead developer and support engineer. I worked with the group quite happily for around 4 months, after which the group's leadership made the decision to stand down and call off our response efforts, for various reasons that are unimportant here.
In the transition period after standing down, people started winding down, which had a nasty side effect of kicking a lot of deep-seated trust issues and personal disputes out into the open. To put it simply, a number of team leads, including myself, had issues with how higher leadership were running the group. In particular, a significant number of people complained that there was a lack of transparency in how people and operations were managed.
It culminated in some substantiated rumours that a small number of leadership would attempt to remove evidence of, effectively, a deliberate lack of transparency, against the wishes of much of the rest of the group. I made an attempt to preserve transparency that ended up backfiring on me, and resulted in a pretty nasty email chain between said small number of leadership and me. The ultimate upshot was my removal from the organisation.
I can't honestly point to one event that was the cause of my removal; there was a lot of conflicting office (and real) politics, personal problems, and trust issues, and I wasn't the only one caught in the fallout.
I'd like to know how I should deal with this at interviews. I'd like to include the experience I gained with this group on my CV, because it was in all honesty some of the best practical experience in the field that I've had. The work we did, and the results we got, are unquestionably good. The whole got-kicked-out thing? Not so much.
If I include this experience, I expect interviewers to ask (a) why I left, and (b) why I was there for such a short period of time. I'll need to have answers for those.
To be clear, this was not a case of ignoring a manager's orders: being a hastily-drawn-together volunteer group, there was no "official" management, and any leadership was formed mostly of the people who got there earliest and shouted loudest (to put it crudely). It was an arrangement that worked while we were in disaster-response mode, but once we'd stood down leadership suddenly lost much of its meaning.
How do I explain this?
