If they were hiring in fall 2018 I hadn't heard about it and I can't seem to find any reference to it. It's not like I'm in that market, though. However, yes, if they were following the same hiring guidelines, we should be seeing a selection by now or very, very soon. Alternately, it's possible that they didn't find anybody they were interested in, or the candidates did not complete the interview process, or what WotC's asking for is requiring a longer time investment from candidates (that seems unlikely, as it would be rather off-putting for a company to require design samples that take longer than three months to complete).
