I have made the examples below.

(1) As a project manager, I go to my clients' companies and talk about business projects with them most of the time. Today, my employer tells me that I will get a promotion soon. In my new position, I will always work in/at the company.

(2) Jack has the most work experience at/in my company.

I am not sure which preposition is correct.

to work for a/the company to have the most experience of anyone in the company to be at the company [for the day or for work or for whatever reason]

to be at = location, geographical or spatially

at home at work at school


I work at a company (insert company name) in a capacity that is important. I work in a certain capacity at my company. at: general in: specific

  • The trouble with your "rule" in the last four words is I work in banking - even more general. The fact is that English speakers say "work at [a company]" more often than they say "work in [a company]" (between 2:1 and 4:1, judging from some searches in the iWeb corpus), but there is no useful rule to account for this: it's an unpredictable aspect of how we use words

(1) I will always work at the company. You don't have to travel outside, "in the company" typically means you are a member/employee of the company.

(2) Generally you use "in". Unless say Jack is a visitor and you want to find out who is the tallest currently at the company (building).
