Update: The recruiter confirmed it's an E4/E5 role and they would evaluate me across both the levels.

Original Post

I recently cleared phone screen and have been asked to schedule full loop. I can see 2 system design rounds, 1 coding, 1 AI coding and 1 Behavioural round.
In my experience E4/E5 has 4 rounds in full loop + 1 phone. Why does this role have 2 system design rounds?
Has anything changed? Any recent experiences?
I am yet to speak with my recruiter about this.
