For what it's worth I don't really care much about your resume other than the fact that it is a signal for if you _may_ be a good hire. My job as an interviewer is to test if you are a good hire and you need to be able to pass that test. I ask easy programmings questions as a smoke test of technical competence. I banter about your interests and past achievements to see if we are able to communicate and get along (as well as probe for bullshit). I ask hard problems to see how you think and your motivation to get the job done.

Having been in a big company, the primary reason we did lots of coding is to ensure that we have enough signal that you can code. One bombed interview may not mean much, but any more may be an indication that you cannot get the job done without some amount of babysitting.
