Make plans to attend TBA, it can be a Hail Mary push for many to get a last minute hire.
If you haven't already had someone else look at your resume I highly recommend you do so. If you've been making it to interviews but not been hired, do some practice interviews with a mentor.
I have a former student who's been looking for that first job and only finally landed it this past week. From many I know who were hiring this year they were regularly getting 50-100 applications to sift through. Lots of open jobs this year, but it seems like lots of people looking to move too. I would guess that with a lot of districts shut down this week you'll see at least a few openings posted next week from people who sent in their resignations after their HR departments went on break for the holiday week.
