You're not the only one. I've experienced many types of interviewing: skyping, verbally coding, online code editing, in-person whiteboard coding, homework/coding tests, programming language trivia, math brain teasers, etc. The funny thing is that even when getting all of the questions "correct," they haven't ever gotten me closer to a job offer than more traditional methods.
You can tell within the first 10 seconds of your first interaction with a company if they are actually interested in hiring you, or just window shopping. The conversation starts with the HR person/hiring manager talking up their company, asking about your experience and then essentially asking you how soon you can start.
In other words, if someone doesn't already have a good idea that they want to hire you based on your resume and experience, no amount of code circus is going to move the chains forward.
