Does this expression make sense?
This morning I came across a foreigner who was looking for 000 University.
She said she is from Paris and is working at International Business School in Paris.
I asked her "Judging by your job, you might have been to many countries.
What countries have you been to before?"
She said "This May I've been to Toronto in Canada."
Then I asked her "Do you like your job?"
She said "Yes, I do."

In my writing, if there are any mistakes, could you correct them?
And what about "Are you satisfied with your job?" or "Are you happy with your job"
instead of asking "Do you like your job?"
Or could you give me another way?

Answer

Generally, this makes sense to an English speaker. However, we could clean this up a tad.

These are the changes I would make, Mari:
[ ]= notes or corrections

This morning I came across a foreigner who was looking for 000 ["000" doesn't make sense. You need a proper name of the University here.] University.
She said she is from Paris and is working at [the] International Business School [there].
I asked her[ , ] ["Because of your job, have you been to many countries?]
What countries have you [visited]?"
She said ["I've been to Toronto, Canada."]
Then I asked her "Do you like your job?"
She said "Yes, I do."

Happy Studying Mari! :)
