I applied online. I interviewed at University of Pittsburgh in June 2011
Interview
half an hour telephone interview called by the PI, and then samples of SAS program were requested and reviewed. I got the admission in the PHD program in 2010, but got funding for the PHD study one year later
I applied through university. The process took 4 weeks. I interviewed at University of Pittsburgh (Pittsburgh, PA) in Nov 2014
Interview
Submit a GRE score, letters of recommendation, CV, transcripts. These are reviewed by the graduate student admissions comittee. Successful candidates are invited to on site interview where they meet with faculty members to discuss potential projects
I did not have an interview. After obtaining admission to the PhD program, I send my CV to a professor and was recruited to this position. This kind of jobs are based on availability of funding and the fit between your research interests and your recruiter.
