Is this acceptable to say the following:
I am working on a project in my company
Will 'for' keep the same meaning?
How about 'at'?
Is there any rule of thumb to make such choices more easily?
I looked at Working in / for / at? but I have a feeling that my case is slightly different. Because here we have an additional noun before "company". I understand that saying: "I work at XYZ" is preferred but what if we have something else coming before? If somebody is working on a project, is he working for or at company?
