I am a Civil Servant, specifically within the Insolvency Service. It is hard to describe my job as it is basically to support all the other teams within the Department that I work. Mostly it revolves around providing figures and statistical analysis to whomever wants or needs it, some low level upkeep of our payments system, helping people external to us upload files to us (it is very specific data with tight validation rules so it's often wrong). However it extends wider than that to a sort of Jack of all trades and in my time I've paid people money, answered general queries, drafted letters in response to complaints, written to MP's, advised on legislative matters, created and presented training to other staff on things from Excel to writing SQL, TUPE to Employee Status.
The pay is terrible, like truely utterly terrible, but everyday is different and most days a challenge as I'm always being asked to do something or for something that I've not done before.
