I just finished a partner round interview (case + fit). Would appreciate some input on my performance as I know what is looked for in final rounds is different from what is assessed during first rounds:
Situation (Case):
1) The case was very un-common with no math. The Partner said he wanted to have a conversation.
2) The partner was consistently interrupting me ; cutting me short when I try to further develop my answers and kept on making me doubt my answers. (i.e. did not let me finish my structure; made think of another hypothesis…)
Aftermath:
1) Despite interruptions and doubts induced by the partner, I maintained composure and assertiveness.
2) I ended positively. Despite imperfections, I am proud of standing my ground without losing composure.
After the case I did some research and answered his prompt with more time and resources available. What I have proposed to him during the interview was not too far from what the research showed (→ key points were there).
