I applied through an employee referral. I interviewed at Citi in Mar 2014

I discussed with an investment banker type what stocks I thought were good buys. We discussed my current experience studying abroad in the UK and why I was qualified for an investment type internship. This was done over the phone and was a 1st stage interview.

Interview
Phone interview to ask why I wanted the job and how can I contribute. The interview was brief and short. Main point is to see if I am suitable for the job and whether am I qualified for the job.

Interview questions [1]
Question 1
Fit questions (why did you choose finance, why citibank), questions about past classes and internships (My previous internship was somewhat related, so I got some pretty detailed technical questions about what I did), basic finance questions (yield of bond at par = ?), brain teaser like question (If you laid every single person on Earth from head to toe, how many times around the Earth can you go?), and last personality-ish question (say something about yourself that is not reflected on your resume)
