Overall those systems frustrate me to the point of finding the hiring managers name and their email address (just google for example @xcompany.com to see how their work email address is formatted) and sending them a personal message with my resume attached. This works at times, while other times it doesnt. But, either way I dont have to deal with those horrible CV/resume data entry systems. Also, since not many are using this hack Im sure the recruiting manager saw my resume vs. it going into a black hole.
You can either reply here or email careers@stackoverflow.com. Thanks!
Needless to say, I didn't even get an interview. But I'm in a fortunate position where I can choose the company I want to work for and that business, with their buggy application process, failed to impress me.
