I applied through university. The process took 3 weeks. I interviewed at Abt Global (Boston, MA) in Feb 2015
Interview
Interviews composed of a series of interviews with managers I would be working with. I enjoyed speaking with managers and learned more about Abt as an organization. The process was somewhat rigorous with back-to-back interviews, but I was allowed breaks in between. No cases.
Interview questions [1]
Question 1
Tell me more about yourself and why you would like to join Abt.
I applied in-person. The process took 1 day. I interviewed at Abt Global in Jan 2012
Interview
My impression was that the interviewers cared a lot about employees' work experience. They were more interested in people who have hands-on experience on many of their on-going projects. Interview questions were could be specific to one step in a survey method. It is recommended to research the interviewers current and past research projects before the interview. It would be a plus to show that you know their work well.
