Which one is correct?
• I am an engineer, and I work "at an" office.
OR
• I am an engineer, and I work "in an" office.
If both are correct, what is the difference between them?
Thanks in advance!

Both are fine and mean the same thing. The second is more common.
Don't use in advance. Since we couldn't possibly see the question until it was written and posted, it was obviously in advance.
Just say "Thank you" or Thanks."
