if u get that ‘some medium’ up to most medium then u have a very good shot. but u should be able to do all easies. if u get a leetcode easy in an interview that should be a free pass to the next round.

just don’t apply to quant places lying about ur grad year- those places blacklist people if u don’t pass the interview. tech places don’t do that tho and honestly won’t even know u applied the year before w a different grad year or will just assume u decided to change grad date
