PwC Data Scientist interview questions

I received a call at around 11 o'clock asking if I was available for an interview at 3 o'clock. After confirming my availability, it turned out to be a technical round where I was asked approximately 20-25 questions related to Machine Learning, Deep Learning, and Natural Language Processing, as well as given 2 Python problem statements to solve. After the interview, I received a call asking for my notice period and expected salary within 30 minutes, which made me think that they were interested in hiring me. However, since then, I haven't heard back from them.
