My curriculum has definitely equipped me with the skills for Kaggle. I did an exploratory analysis on one this dataset here and will be attacking some of the competitions once I complete a bit more of my Machine Learning content.
Udacity has plenty of success stories on their website. There are lots involving programming as well — here’s a cool Reddit post. As for me, I got a part-time job at a startup as a data consultant through my MOOC experiences. I don’t have any experience with companies with larger HR departments yet, though I will in a few months and will be writing about it.
No need to apologize. Your English is good! :)
