Well, I'm uncertain if this is truly a bug or not, or if its just Imgur who happened to 'mess up' here, but there appears to be a slight issue with SE's handling of career company logos, and their banners:
As I'm sure can be seen from the image, the logo blocks the banner text. One solution is to simply move the thing, or it could (maybe) be removed altogether.. though I do realize that this would likely cause complaints.
On the possibility that it cannot be moved, maybe the companies could be alerted of how such an ad would look.. or even offer the possibility to not display the logo.. or something else, if anything. I'm honestly wholly unfamiliar with how that side of things work, so sorry there.
