Capital One Consultant interview questions

Interviewd by Capital one for a lead developer , right to hire position . After initial exchange of email with staffing company , staffing company conducted their own screening, then forwarded resume to the capital one , capital one conducted a phone interview first , interview lasted for 2 hrs.Looks like the interviewer want to find some thing that i can't answer. The position is for consultant in java , j2ee technolgy , so questions were asked started from basic OOPS to Advacned questions all kinds of , including some syntax and unix commands too:). I never had such a horrible interview in my life . Next one to one interview , four people grilled me to an extent , where i want to say ok thanks and leave. I got selected , but declined the offer. Hope this one helps to others.
