The screening process took a long while (2+months) once I applied online. After the first recruiter call, there were 3 online assessments - verbal, numerical (both timed) and personality. The onsite interview was scheduled in a week. There are 4 interviews 45 min each - 2 behavioral (by IT managers/BSAs), 1 job fit (supposedly by the hiring manager and 1 case by a business person. Each interviewer has a question book and sticks to the same, jotting our answers as we speak. Typical behavioral questions ( 3 for each interview) are available in a Google search. It helps to be prepared with a few sample scenarios for these. Job fit questions are standard also - business vs technical requirement vs design with an example and functional vs non-functional, traceability matrix, testing support etc. My case was a problem to reduce the # of credit card welcome packets, with a critical path activity math exercise.
Capital one has a fabulous campus with demarcated interview rooms. My D-day had about 10 candidates. I was the only one in business casuals and everybody else were in suits.
