Hello @oliversnaf and welcome to the forum! Please refer to this post on how to include a read-only link of your project so others can interact with the problem and do their best to figure it out.
Here is the page available in read only ( [URL]), it concerns the section 42, I do not know how to apply the link of the job offer to the width of the line.
On the template available here ([URL]), the grid is linked to the page collection, how is it possible?
Currently your are using the grid element for your .Career row. I cannot be associated to a link.
What you can do is use a Link block element for your .Career row and associate it with your link. And then, applying a Grid display to it.
