Advice for applying to a pet store

[Eric Alan]

To add, there is almost nothing worse than an employee who can not answer basic questions about their products. It dramatically takes away from the store's credibility. Make it clear that you are there to learn and are willing to study up, even on your own time. You are expected to sell which means knowing your stuff.

Make it clear in the interview that if a customer asks a question that you don't know the answer to, you will find the answer, or someone who does. There is no shame in that. The cardinal sin in retailing/seller is making up answers due to pride.

THIS. There's getting a job (which is the easy part), and then there's keeping a job. This is how you keep one.
