How long can you study in a day before an OA before it starts to have negative effects? /u/Professor_Goddess CSCQ protests reddit

Basically wondering… Is there a time one should plan to study before an interview to be the most sharp? A couple hours maybe? 4 or 5? Obviously studying in the days and weeks before is important, but I wonder what the optimal amount is in a day. I’ve got an OA tomorrow for Google SWE summer internship. Hoping it isn’t too rough 😅
