I have not cleared a few questions in an Accenture interview. What should I do?

I got a lot of cross questions on extracurriculars and few questions on technical aspects. There are a few questions that I couldn't answer and there are some questions which gave me an unsatisfactory feeling.

Well, Let me tell you my experience. I sat for an interview with Accenture which is a group-face to face interview. The panel has 3 professionals from Accenture. The questions are straight forward on my resume, projects, academics, extracurriculars and hobbies. One among them grilled me on “Why Accenture", and on some of the behavioral questions. I got a lot of cross questions on extracurriculars and few questions on technical aspects. There are a few questions that I couldn't answer and there are some questions which gave me an unsatisfactory feeling. Still I got an offer from Accenture. Yayy!!! What happens is they don't expect an interviewee to know everything. As per my experience and my friends, they look for an honest answer and how you responds to the questions, you have no idea. We can't actually judge from the interview, just have to wait for the call.

So, Be positive!! If you are selected, well and good. If not, learn from your mistakes, prepare well and break a leg in the next interview. Oppurtinities are ample. You just have to be at right place at right time.
