[Star Wars] How come Kylo Ren can use the Force to get into people's mind yet Vader needed the help of the IT-O Interrogator?

Vader can use the Force to get into people's minds.  But it only works on the weak minded.  Leia is not weak minded.  Kylo Ren couldn't get much info from Rey either, and her strapped to a table ready for an Interrogator if it proved necessary.
