Detail-oriented
Most times, results or mistakes are always found in the details we forget to take cognizance of. The ability to remember the intricacies of a task at hand especially when offering help with essays, dates, numbers or facts will go a long way in proving your competence. No one likes to say a thing over and over so the best way to avoid forgetting information and to ensure that when the details of a task are being given, a pen and paper is at hand to jot them down.
Similarly, in carrying out a task, especially a research or accounting-related tasks, paying attention to details could leak to easier result generation. Or in the case of a customer care business, the complaints of a customer are also important.
