WisdomTree Investments Sales interview questions

Give a good Overview of Exchange Traded Funds and Exchange Traded Commodities, especially why Wisdom Tree Funds are better than funds of a competitor and them present to a senior member. Make sure to research the Funds and Exchange Traded Commodities, very informal process, small team and small office but growing. Relaxed atmosphere, first an informal coffee meeting with a Sales Person followed by a presentation in the office on another day, not the day of the actual interview
