Goldman Sachs Strategist, Credit Flow Desk interview questions

I networked at an on-campus recruiting event at my university. I seemed to impress some of the recruiters, who quickly passed on my resume to strategist teams at several of the trading desks. I was contacted over email about a week later and set up a phone interview for 3 days later. The phone conversation lasted 60-70 minutes. I was incessantly grilled on technical questions about finance, probability theory, and computer programming - no warm fuzzies or pleasantries were exchanged whatsoever.
