The interviewer asked me a bit about myself initially, followed by a few questions surrounding my project during my previous internship.
The interviewer then asked a few questions on things I had mentioned on my resume (like stock trading/investing).
Tips: Be confident throughout. Prepare a nice introduction that sets the tone right for the interview. In the introduction, focus on the things that you are the most comfortable talking about, and guide the interviewer in that direction. Know your resume well.
