How do evaluate a Consumer product company or opportunity and if it is a good job to take?

There is no right answer, but here are a few lenses I've used when providing counsel to others and in considering the companies I've worked with:

• Is this a product that I'm personally excited about? I don't have to be the ideal customer, but is there something about the product that excites me - it could be that it's a problem I'm passionate about solving, an approach that is truly innovative or differentiated, a customer that's a lot of fun to work with, or a business model that creates strong competitiive advantage
• Are the secular trends in its favor? Is the company leading the way in transforming how things are done, or focused in an area who's time has passed. Another way to think about it - is the potential target audience growing or shrinking?
• Does the company have a unique shot at winning in this market? Some markets are large enough to support many many companies - others are winners take most. Which type of market is the company in and is it well placed.
