Interview
The interview process in its entirety took around a week. A few days after sending in my resume, I received an email from an HR representative. We then scheduled a Skype interview, which involved general questions about your experience. The first step went quite smoothly for me, so I moved on to the next case which was a 'case study'. Well I would really call it "job interview homework."
Unfortunately, this is where it ended for me.
Overall, it was quite a difficult process, not because of the "case study" but because they are obviously have extremely high standards for potential interns. Also, from what I can tell, there is a lot of competition, and you need to essentially be the best of the best.
