Application question(s):

• Do you have previous experience working as a purchaser, including negotiating prices with suppliers? Please give details
• Have you used any inventory management systems before? If yes, which ones?
• A supplier emails you with their updated price list. One of our key products has increased in cost by 12%. This product is important for maintaining competitive pricing on Amazon. How would you respond to this situation?
• You have a component that is used in two different bundles:

SKU A sells 10 units per day.

SKU B sells 3 units per day.

You have 100 units of the component in stock, and no more will arrive for at least 30 days.
When we send stock into Amazon, our goal is to have at least 30 days of stock available for each SKU.

How would you allocate the stock between SKU A and SKU B for the next shipment assuming both have 5 days of stock left, and why?
