Student or Learner
All, in a dilemma here as regards to at and for. I have always been tempted to use "for" in the following scenario. Please advise.
Example: I worked at/for Microsoft for 10 years in 90s.
Also, I think expressing it in another way would be- I was with Microsoft for 10 years in 90s. Does it imply the same meaning as above?
Many thanks in advance!!
