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

Yes

The word "conseguiu" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The primary difference lies in pronunciation. In Brazilian Portuguese, the "e" is typically pronounced as an open or mid-vowel [e] or [ɛ]. In Continental Portuguese, the "e" is much more closed [e] and is subject to significant vowel reduction, meaning it often sounds much shorter or nearly swallowed in natural, rapid speech. Additionally, while the word itself is the same, the syntax (how the word is placed in a sentence) and the accompanying vocabulary often differ between the two dialects.
