Two things kind of leave me undecided:
1) Narrow brief: Here they are very narrow and specific about what areas would be suitable and it is clearly very closely aligned with their own interests. (However a blog post from one of the companies on the judging panel gives a more open ended brief: http://import.io/barclays-social-enterprise-hackathon-2013/)
2) Outcome: There aren't any "prizes". I suppose this is social enterprise, so you could consider a monetary (or similar) prize as slightly against "the spirit", but really I was kind of expecting more of an incentive from a huge multinational bank?
Anyone else seen this or otherwise have any thoughts on this event?
