原文：I has a job interview tomorrow for the position of marketing manager. I hopes that I am well-prepared for this opportunity.
Possible grammar errors:
- "I has" should be corrected to "I have" because "has" is the third-person singular form of the verb "have" and does not agree with the first-person pronoun "I".
- "hopes" should be corrected to "hope" because the verb should agree with the subject "I", which is first-person singular.

Corrected text: 
"I have a job interview tomorrow for the position of marketing manager. I hope that I am well-prepared for this opportunity."
