The last time I was job hunting was 2012, and while that wasn't that long ago, it seems it.
I am a firm believer that you should update your resume every 4-6 months, including every speaking engagement, lecture, paper published, etc., so that when you are ready to job hunt you won't be stuck scratching your head about the details of what you've done since *insert year here.
On the other hand it's the cover letters--I've sent out at least 25-30 since I began my job search in September--that are giving me grief. I found some interesting articles this weekend and thought I would pass them along in case you are too!
