原句應該是......Jack Welch ,whom he....worked for at GE.....    

他在傑克·韋爾奇（Jack Welch）的模範中扮演自己的執行官，他曾在GE的NBC工作。

我是這樣理解的，可以把原句子拆成兩句↓

1.He fashioned himself as an executive in the mold of Jack Welch.
2.he'd worked for Jack Welch at GE’s NBC.

然後因為兩句都有Jack Welch這個人，於是便可以用關係代名詞who來替代他，並且第二句的Jack Welch是worked的受詞，所以who要變成whom,然後再加上為誰工作的for，就會變成for whom.

He fashioned himself as an executive in the mold of Jack Welch,  for whom he’d worked at GE’s NBC.
