I was given a CasaOne Specific business Problem . I spent 3 days solving it and made 15 page ppt for the same. After submitting my solution, I got a response that they will not be moving with my candidature at this point of time , with no feedback on assignment submitted. I have heard of organizations which in name of assignments steals ideas from the candidates and I think this is one of them. It simply makes candidates to work on their Product cases on a free basis, ‘collects’ their unique ideas and rejects them.
