What does "Application review begins ..." practically mean in job ads in computer science in USA? As opposed to Do they really mean &quot;in all areas&quot; and &quot;will continue to be accepted until...&quot; in Computer Science faculty opening ads in the US? , we sometimes even see a softer language without a final deadline in faculty opening announcements:


  Application review begins Date Y.


No final deadline ("until...") is given. How long after Date Y can one apply in the typical case?

(An aside: Assume that the applicant cannot get this information directly by asking, e.g., due to the absense of contact data, and that the applicants network, including that of the supporting advisors if there are any, does not cover the location.)

This question seeks answers from folks who have participated in search committees, have supervised them, or have received feedback as applicants. If it is the case for you, say so.
It means that, shortly after date Y, the committee in charge of reviewing applicants will meet and discuss the applications that have been received up to that point and, if they like some of the candidates, they will be invited for interviews and, depending on how it goes, may get an offer. They committee may revisit the applicant pool at a later date and, if the position is still open, they may consider further applicants. So, in principle, you can apply whenever you want but if you wait until after date Y, you may miss out. Of course, it can happen that all good candidates are late but you shouldn't count on that.
