There could be a lot of reasons why they may have passed, and it could have absolutely nothing to do with you or your personality.

If it was just one company, I wouldn’t start trying to change who you are. If you make up a new personality for the interview and get the job, then what? How long can you keep the character going? Do you want to work with people you can’t be yourself around?

In terms of what to possibly change, that’s almost impossible to say without seeing what you’re like in an interview.
