Fidelity Investments interview questions

There was a phone screen by HR, followed by a phone screen by a developer. At the former I was told that quantitative skills were important to the position,while at the latter I was told that they weren't and then I was asked to rate myself as a programmer on a scale of 1-10. When I said 6-7 I received a string of extremely easy technical questions such as the differences between a do-while loop and a for loop. I was not asked about object-oriented programming at all, although a lack of that knowledge was given as a reason in the subsequent rejection letter.
