Having interned at Candesic and even extended my stay from 6 to 12 months, I'm surprised by the above comments.
I found the experience enriching and was engaged throughout the duration of the internship. A week after starting, we received a two day McKinsey-style training seminar by the managers and the partners. A month later, I was working on my own portion of a project. Six month later, I was attending seminars and conferences speaking about our work and making new contacts. That's exceptional for an internship.
I've now returned to Candesic full time after working in PE and find the team just how I left it: knowledgeable, driven and entrepreneurial. And that's great because we are extremely taken by projects!
Hope this helps give a more faithful view.
