Tesla and Apple compete for the same talent in fields like software, batteries, supply chain, and mechanical engineering. So there has always been a lot of employees that jump from one company to the other.But recently, the flow has been going from Tesla to Apple, according to CNBC, which says that the iPhone maker has poached at least 46 employees from Tesla in 2018. Tesla CEO Elon Musk once said that "if you don't make it at Tesla, you go work at Apple."
