I started out as a desk analyst, doing spreadsheet and programming things for all the traders on the government desk. I went to a non-target state school, and my entry job to the ibank was in the IT division as a VBA Excel and SQL database developer (back when that was special).
After a few years, I got a shot as a UST bond trader, making markets to the customer base via the sales force and am now a prop trader. I am trading mostly the same product I used to be a market maker for (govt bonds).
Ask me anything.
