Very slow. Low efficient and non respectful. I won't work there in my whole life. They will not give you a response. Even if you called HR and they never call you back
I applied online. I interviewed at StataCorp in Dec 2012
Interview
It was a phone interview, not so difficult. it was just to determine if the candidate might a good fit for the advertised position before inviting for a face to face interview. I was asked a few technical and theoretical questions to measure the background. no need to worry, they were pretty basic.
