Orientation is generally, and unsurprisingly, of sporadic and limited value particularly to incoming pathology residents. Stuff like don't smoke where it says "No Smoking," don't harass the homeless out by the parking lot because someone got stabbed last year, financial stuff like "sign here so you can get a paycheck, even though you already filled out all the contract stuff with your department already and they could be doing this in -their- orientation," take more naps so you won't be tired working 36 hours straight, our psych support office is over yonder, here's how to enter orders in the EMR, and be sure to finalize your discharge summaries within a month or everyone will be sad. But, it's an ambiguously necessary evil, and you get a chance to figure out how long it takes to get to work before you actually have to start work. Too bad for yall with 300k debt and could use that week to, I dunno, earn a paycheck to pay for food, we'd just rather do orientation and waste your time without paying you yet. Welcome to residency! Oh, and by the way, you get to do this all again the first few days of residency as part of your program's orientation (though at least that will usually have more relevance).
Sometimes you learn things useful, and you may get to meet some people, but it's rarely an efficient process.
