No updates from HR since last interview

So I’d applied to a role at Accenture S&C SN and appeared for all the interviews that were scheduled. My last interview was on 24th Feb and hadn’t received any update until I called the HR who was scheduling the interviews. He mentioned that I’ve cleared the last round and should’ve received an email and call from another HR for an HR round. He messaged her just last Friday to follow up with me but she hasn’t called yet. Is Accenture really this slow or could there any another reason for not calling? The status on workday just shows the last scheduled interview. Neither have I received any emails since the beginning, strangely.
