I guess whether people are laid off or just looking for new opportunities, it may not be easy to keep all the resumes, responses, contacts and interview results together, also maybe they already applied for this position? to this company? If so, when and why didn't they still have an offer from them? If they rejected, for what reason? what about reference contacts? test assignments? so an online service for keeping all information about their job search process may be helpful.
