I initially applied for this position in May 2012. I received a call mid-October asking if I was still interested in the position, and I said yes, so we scheduled an interview for the following week. The HR staff kindly sent me an e-mail describing the position, the salary, and my interview schedule. I was scheduled to meet with 4 groups of people, from the HR director down to the other DNA Extraction Techs.
GeneDx is still a pretty small company, but it seemed very well organized and the working environment seemed nice. I met with the HR director first, and we talked for about 30 minutes, during which she asked me typical interview questions. Then I met with the Assistant Director of Clinical Laboratory Operations, and she was a little more specific with her questions regarding my experience, but much of it was still your typical behavioral interview questions. If you have research experience, be prepared to talk about them. I also met with the DNA Extraction Tech team leaders, and they pretty much asked the same questions as the people before them. One math question threw me off, but it's not the decision-making question, so don't be too stressed out about it. I finally met with a DNA Extraction Tech and she gave me a tour of the labs and we talked for a little bit.
The whole interview took about 2.5 hours. I was scheduled for 1.5 hours of interview time, but I prepared a lot of questions beforehand and they asked me a lot, so it took much longer than expected.
I received an offer about a week and half later.
