朋友去面试一个职位《 Head of Project Management Office》。
她回来问，Head是个什么职位，级别类似经理、总监还是其他？
解释如下：
In the corporate setting, the head of a company is the "Chairman" and "Chief Executive Officer" (CEO). He/She is the top-ranking executive.
A person can also be the "head" of a department, a team, or a group.
The common hierarchy of heads is as follows:
Chairman/CEO
President/COO
Vice President
Director
Manager
Supervisor
也就是说，这个职位取决于部门大小，都叫head。就是咱们说的头儿、老大。 我们部门老大，和我们公司老大，不一样大小，但是都叫老大！你懂了吗？
