Why do recruiters ask you such personal questions at some points then others which seem completely irrelevant? Get an inside view of the process in which HR or recruitment agencies will try to determine if you are the best fit for the job you are seeking...and more importantly, how you can properly put forward your "extra added values" in both technical and transversal areas, from robotics to intercultural communication. It's all in the preparation, sure, but you need the self-knowledge and some cogent stories to share, too!
