Still your reply now gives some Ne sense so i dont really know.
As for einstein overall i always thought of him as INTP, but i remebered recently that he was infamous about the fact that he wouldnt change his clothes style or maybe wear the same clothes everyday because he would like to avoid contact with materialistic world and trivial matters as much as possible to focus on his thoughts. That shows a poor Si and maybe unconscious Se.
So he could actually be ENTP.
Not that i can take only this into account.
Still i believe him to be much more of an introvert than ENTPs. But one thing i know about ENTPs is that they can regain energy from a new thought as much as they can from talking with people.
So both types are possible.
He strikes me as a Ne dom or auxilary overall because doubt was his forte.
