This Reddit post describes a final round interview for a Trading Internship.

Final Round:
The round started with a Q&A session with the head of European trading, emphasizing asking interesting questions. It included:

• Estimation questions.
• A group session where candidates marked markets on a quantity they had all previously estimated.
• Plenty of behavioral questions, which candidates should know "off the top of their head."
• Technical questions were "all green book," implying a need to study this resource thoroughly.

The advice given was that the best experience for interviews is doing interviews, and that even if this opportunity is missed, it's invaluable experience for future final round interviews. Other comments suggested practicing mental math on sites like rankyourbrain, puzzles from brainstellar, and playing chess and poker for pattern recognition and betting scenarios.
