Seems normal that the number of employees in Sales would follow the rate of product sales.
Might be different for Intel though, everyone has to drink at the same oasis.
If you’re at a company and you look at your engineer to sales ratio you might think to yourself “gee, we have so many sales people!”
That’s because there’s not much multiplying factor to sales roles. There isn’t a lot of potential to automate like engineers can do. A salesperson only has so many hours in the day and they’re fitting maximum one or two customers into a one hour slot of their time.
