Turnaround and Restructuring Summer Associate

I applied online via Handshake and received an email saying I got a 1st round interview about a month after. The 1st interview was entirely behavioral and was held on MS Teams. It took a while to hear back about the superday but about 3 weeks after the 1st round I was invited to the superday. The final round consisted of 3 interviews, 2 behavioral and 1 technical. The technical interview was mostly based on RX but it helped to study banking accounting/valuation questions. The decision-making process did not seem transparent at all. My guess is the interviewers make notes and the HR team actually makes the decisions. About 3 weeks after the superday I got a call saying I got the offer.
