I've been from local companies (Real Estate, Warehouse for Food Manufacturing, Warehouse for Construction supplies) where I'd learn office activities like planning, organizing, and documenting files that we need to process our everyday live operations using computer tools like Microsoft Office.
Then I'd recently worked in a Call Center Company where I'd learn how to do multitasking using different tools from our client (owner of our product/account) while talking to customers all over the world (inbound calls), addressing their concerns regarding our products, and providing them proper resolution and recommendation.
