Videojet Technologies C++ Wince Developer interview questions

face to face interview with software manager, none of technical stuff, more like formal conversation. Interviewer asked me how to measure my technical ability!!! ????? then asked me to send him some of written code !!!! I sent them three code snippets, two of them fully documented and one very simple but very tricky code (without any explanation) that on surface looks like helloworld kind of code but under hood it was code that shows typical vulnerability in c++ code to manipulate array overflow to change the instruction pointer. I purposefully included this code without any explanation as I had doubt about myself being technically overqualified for the team. And feedback was just as I expected They were concerned at the lack of documentation and notation within the code I had provided, although they did appreciate the complexity of some of the code I have written. Meaning they were baffled with simple code and could make out of it.
