Do we say:
- He works in an investment bank in Dubai
He works at an investment bank in Dubai
- 70% of the analysts use this method
70% of the analysts uses this method
"He works at an investment bank in Dubai." meaning he is an employee of the bank.
"He works in an investment bank in Dubai." may mean, for example, He is an electrician, he is currently working in an investment bank, renewing the data cables.
This is how I understand these kind of sentences. Would you ( and of course, other native-speakers and teachers too) explain whether there is
a defect in my understanding of the sentence or not ?
Thanks for answers in advance.
