PwC AI Engineer interview questions

I did an introductory interview, online assessments, an interview with HR, and a case study involving coding. Apparently I failed the coding test which I thought made no sense due to the massive scope of the task and extremely limited amount of time given (and yes, I have previous relevant experience so I am qualified to say this). It was very strange in comparison to other AI Engineering interviews I have done, so I felt like they really wasted my time because I anyway had no chance.

Easy two rounds just describing my knowledge, no coding, then final interview with manager. Everything remote. The recruiter was very responsive. She contacted me on LinkedIn. Got an offer after 4 weeks
