The job postings are vague and do not go into detail, this is likely because it's possible to be placed in multiple areas of the company. One thing that's not mentioned in the postings is working hours, it's a 10am-6pm EST operation with very little flexibility. The interview process was smooth and the rejection was polite. Initial interview was a recruiter screening that asked general questions about background and why you want to work for them. Second interview was a hiring manager, that was concerned with placement and company fit. Third interview was technical and supposedly there are more additional panel interviews if you make it past the initial screening.
