From experience I would say running the OSS project is definitely harder, but the type of person who is capable of making a successful OSS project is not the type of person who can chain themselves to a chair for 3 months and practice interview questions. Studying for FAANG interviews is arduous and extremely non-rewarding. It is like the extreme opposite of an OSS project, where you put in the same hours and have exactly nothing to show for it.
