Hire engineers to solve your company issues, not complex maths problems you don't have

Let's face it, your company is not a Big Tech company. You, the reader, are probably not working for Google, Microsoft or Facebook and it's ok. A lot of companies not so big have a huge impact and very high tech challenges.

But not being a big tech company also means you probably won't be good at what you're doing if you act the same way Facebook or Amazon does. This is true for tech choices and system architecture. This is also true for recruiting software engineers.
