I'm a summer intern at Goldman in S&T. Days for interns are the same as for the MD (managing director) you're under. You try to get in just before they do and leave when they do. Generally this is 6AM-7PM for me. I don't step foot in the office after 7PM Friday and have zero reason to do so until Monday.<p>On the IB side working 9AM-11PM, with many days working to 2-3AM, is absolutely the normal. As is working on each day of the weekend. However, these new hours are being enforced by HR heavily - to my understanding, there's no reason for them to apply to S&T - although I'm not sure it'll mitigate any stress.<p>The issue with IB internships, like any internship, is that you have huge gaps of lull time between projects. However, when you do get projects they're generally time sensitive and need to be done regardless of how long it takes you. This is the life of IB analysts, that those doing the IB internship are lining up to try to get, because it all comes down to doing your two years and going to somewhere (supposedly) bigger and better.
