Positives outweigh the slight negativesThe good thingsGreat environment for learning and trying out market research. It's part of the company's imbedded process to actively take in interns. Interns are generally treated as equals (to the Full-timers) and your contributions are valued w/o distinction.
The challenges1. Long hours given that the work-load is project-based (for those who are concerned with long hours)
2. Unstructured training + learning
You learn as you go about helping your team with their tasks, and across the internship period, it is ideal for an intern to have experience a comprehensive range of tasks that a Market Researcher does. This also means however, that learning opportunities for an intern arise only when the full-timers have the time and space to teach you. This happened in my case, and I spent the majority of the time relieving the full-timers workload by tasks I am familiar with such as bidding for proposals, project management etc. Coupled with the huge project in-flow, it was tough to allocate the time to train me.
