deadlines for firms work much the same as law schools - they consider resumes as they come in. While they may continue accepting resumes and "considering them" up until February, I'd bet that they've hired any 1Ls they're planning to take well before then (but may make an exception for a late applicant with a connection at the firm or a stellar resume).
Also, Cincinnati isn't exactly at the top of the list for major national markets - the regional markets may well hire later than the more major markets like NY, DC, LA, Chicago, etc.
