Presentation + behavioral interview + a bit of a technical test.
I think it wasn't particularly difficult as long as you are abe to present your case well with clarity, detail, and showcase your critical thinking, it will be okay
DSA style questions for a data and AI role for the written potion of the interview and a case study with 10 minutes to prepare and 5 mins to go through your solution.
"Tell me about yourself," "Why should we hire you?" and "What are your strengths/weaknesses?"
Also they ask behavioural questions (e.g., handling conflict, teamwork) and situational questions about your work history...
very nice interviewer. asked personal questions, got to know me, didn't ask me about pwc which I liked. placed more of an emphasis on the person and who they are and what they like
