How much does a Sales Engineer at Siemens Healthcare earn? Help a friend to ask, salary and benefits plus bonuses, thank you!

If Siemens own sales, then the salary in 7000-8000, if it is the agent side of the sales then this is not certain, some can get 5000-6000, some only 2000 more, but the agent there is the benefit of a commission, sell well, if the commission processing capital can reach more than 20,000 per month, and the agent side of the way to avoid taxes, Siemens is not able to evade taxes, so although the basic salary of large companies is high, but the limitations are also large. How do you choose yourself.
