Is the word experiência the same in Brazilian and European Portuguese?

Yes

The word is identical in terms of spelling, grammar, and meaning. The only difference is pronunciation:

• Brazilian Portuguese: The pronunciation is more "syllable-timed." Vowels are generally more open and clearly articulated, making the word sound more rhythmic.
• Continental Portuguese: The pronunciation is more "stress-timed." Unstressed vowels are often reduced, shortened, or even swallowed (elided). To a Brazilian ear, a Portuguese person saying "experiência" might sound as if they are shortening the middle syllables significantly.
