yeah I do feel like the PhD system is not uniform in terms of students’ experiences. some get out quite quickly if their advisor is chill while others are stuck being stack ranked in their labs or doing grunt work. your fate is basically in the hands of your advisor..

Which is why you should shop for the advisor and then tailor yourself to the labs you want to apply to. Interview current and former students. Go to conferences where that lab is presenting papers, etc. Have some solid blue collar academic skills like cleaning data, doing instrumentation, hell even making bad ass slide decks will get you noticed. Getting a PhD is similar to landing the job you want. Also showing up with a problem you want to solve that aligns with the lab AND the skills to pull it off, boom!

During undergrad a bunch of us got good enough at electronics and the machine shop that we had grad students asking US for help. We didn't realize it at the time, but just the instrumentation work could have landed us many a phd program, we were just having fun.
