I applied online. The process took 1+ week. I interviewed at CompStak (New York, NY) in May 2013
Interview
they send you some data to manipulate and ask you to send in a video about your self. all in all the company seem really nice. If i had another chance would apply again.
After submitting the online application, I was asked to complete an Excel task and submit a video self-introduction. They were pretty prompt with their communications. Within a day or two of submitting my completed task and the video, the informed me of the result. From first submitting the online application to the final communication, it took under 2 weeks.
Interview questions [1]
Question 1
I didn't actually make it to a face to face interview. The Excel task was just generating three charts that could be used for a quarterly report and explaining why you chose to include those charts.
