Please don't waste your time giving interviews for Protiviti. They are highly unprofessional. I gave four back-to-back interviews and got feedback from a recruiter that I am the strongest candidate. I kept waiting for the offer letter but, in the end, they rejected my profile stating that according to them, I was not showing much interest in joining Protiviti. I don't understand how can they be so judgemental. I gave them my time for the interview. I could have accepted any other reason for the rejection. They just wasted my time. They could have rejected my profile in the very first interview giving the same reason that I am not showing interest. HIGHLY UNPROFESSIONAL BEHAVIOUR.
