Name for me the main types of coffee beans.

If you are a real coffee nut, you likely know there are a variety of beans available. The interviewer wants to know how much experience you have with coffee. How you respond will show the hiring authority how much training will be necessary if you are selected for the job. Share what you know. If you don't know a lot, that is okay! It's important to show you have a genuine willingness to learn.

"From my research and training I know there are four main types of coffee beans including Arabica, Robusta, Excelsa, and Liberica. The woody taste and rarity of Liberica beans mean they are not as popular, or readily available. Arabica is the most common bean used in North American coffee shops, accounting for around 60% of the coffee brewed today."
