Do you need to include company descriptions on your resume? Well it depends on who you worked for and what you expect your audience will already know about them.
If you worked for Walmart, for example, there's no need to describe them - everyone knows who Walmart is. If you worked for any other relatively known retailer and you're continuing your path in retail, there's also probably no need to describe them. Most retail recruiters know most retailers.
However, if you're applying to new industries or if you worked for obscure companies, then you may want to include a brief description. The reader won't be able to put your experience into context if they've never heard of the company you worked for.
Hope that helps!
