word choice - Which one is right — "He works at company X" or "in company X "?

I usually use "at a company" but I have encountered some articles using "in a company", "in XYZ firm" or "in an organization".

Which one is right?

Answer

Use:

I work in/at/for a company that makes microchips.

I work at/for Intel.

I work in/for Intel's accounting division. (in sounds more natural in this case)

There is virtually no difference in meaning, except that I would notice:

• 
  

  for tends to emphasize the relationship you have as an employee to your employer

  
  


• 
  

  in / at are more about the physical place (this is where you go to work every day)
