This is a hypothetical question so no hard facts about conferences etc.
Say for example there is a conference at your own university that you get to present a paper at but you also get accepted at another university's conference to present a paper at as well.
For this example we will say that both conferences/universities are of the same standing and there is no disadvantage to attend the other one such as cost etc.
Would both look equally good on a CV or would there be a view that the presentation at your own institution would not carry as much weight when viewed by, for example, by a hiring committee?
