    Philippines - Last active: 5 days ago - Tests: 5

    I have 13 years of work experience in a Business Process Outsourcing company where I dealt with different customers over the phone and through emails. It is a job that requires diversity and good communication skills because it is basically communicating globally with people of different genders, age groups, values and cultures. I advanced to the administrative level as a Coach for Performance Excellence during the last 6 years in that company. I handled different teams of 20 to 25 agents for coaching, mentoring, reviews and assessments. I have been a freelancer since April 2014 and I’m now a part time Call Evaluator for U.S. based car dealership centers and have been a telemarketer for a client based in Australia. With work ethics, I am a detail oriented person with strong organizational skills. I always pay attention to details to make sure that every aspect of the job is done correctly. I also have a keenness to every detail not to miss a piece of information that is relevant and material. In accomplishing every set goal in a timely manner, I have the ability to manage time effectively and to set priorities when a job comes with different duties and responsibilities. I finished a technical course which is Computer Operations and Proficiency with Programming Concept. So overall, with my work experience, education and work ethics, I believe I am a bit of everything from a customer service agent to a data entry specialist, an appointment setter, an email support specialist, a telemarketer, a virtual assistant, a trainer and a team leader.
