Oracle OCI interview - on-site

Hi, I recently completed my phone interview with Oracle for software engineer position - frontend. And I have a onsite interview at Seattle. I just have 6 months of work experience and I am assuming they are considering me for a entry level position. Wanted to know what can I expect in the interview rounds. 1. Leetcode - easy, medium? 2. Design questions ? 3. How many rounds of coding and how many behavior rounds.
