Before residency, there arrives a special time for each pod student when they will learn to function - pretty darn well - with relatively little sleep. It begins in a magical time called "3rd year"... and even moreso in "4th year."
Joking aside, there are F&A residency programs where you will be run ragged. Bear in mind that pure weekly hours do not tell the whole story. 10hrs per day of outpatient clinic is nothing, 10hrs of hospital floor duties (rounds, ER calls, consults, etc) or academics becomes a bit more taxing, and 10hrs hours in a row of OR surgery is a downright killer (mentally and physically). Most resencies are a mix of all those things, but each one has different proportions and emphasis.
You do clerkships during 4th year to spend a month at a hospital with a residency program. Residency is a very important decision, so I think it's best to pick a school that gives many clerkships before residency interviews and then pick clerkships where you think you want to do your residency.
Residencies come in all flavors and types:
-laid back... (~40-60hrs per week... usually bare minimum training, esp in the OR)
-tougher (~50-70hrs per week... usually avg to very good training depending where you go)
-"high powered"... eat/sleep/breathe podiatry for 2-3 whole years (~70-100+ hrs per week... usually good to excellent training).
Out on 4th year clerkships, you will gain a lot of insight on programs and realize what you want. Do you want the tip top training at the possible expense of your personal life (family, friends, hobbies, etc?). Do you want to risk minimal training and competency in exchange for an easy residency? If you're anything like me, you will come to realize that you want the solid, practical residency training... while still having time for a decent life outside the hospital. That kind of residency program is certatinly out there and available in podiatry.
