PwC Audit Associate interview questions

I applied thru their job posting in Linkedin, then I received an email inviting me for an online exam. I had to reschedule because it was on my vaccination day. The HR recruiter was kind enough to reschedule. The online examination was a mix of English grammar questions and situational essay questions. After around 40 minutes, I received an email from the HR inviting me for an interview same day in the afternoon. The interview with the HR was about getting to know me and if I am fit for the position. The questions were about what's in my resume and some situational questions as well. The interviewer was kind and listens very well to what I say. I only had 1 interview, I wasn't invited to another one after that. The deliberation of my application took 3 weeks. The HR kept me updated in the first week, but after that, I did not receive an update so I thought I got rejected. But 3 weeks after my interview, I received a message from my recruiter extending me a job offer already and inviting me to discuss it over video call.
