Had an interview with EY GDS, submitted relevant documents. Still no update or further communication from them.

As the title says. I had my interview with EY almost a month ago for a Staff Core Audit position. Had the necessary qualifications (role needed an ACCA Affiliate fresher). A week after the interview, they made me submit my Aadhar Card ( Indian Resident ID Card) and Candidate Information Sheet along with my updated CV. However, its been almost two to three weeks and they haven't sent me any update from their end. I called HR multiple times and they picked up only after the 5th or 6th attempt, and at that point they seemed annoyed about the fact that I called and told me they'd update me very soon and they have a lot of candidates to go through.

How long does this process usually take? Is it taking long because it is a freshers recruitment drive? Should I be afraid of my prospects? Any advice?
