There are two parts to this professional. Calling recipients and serving the documents. It can be trying at times to locate individuals and completing the work as people work various hours and also avoid being contacted.
You become a real "people person" as you have to deal with many different personalities, some not so kind and still remain composed and professional. There isn't much interaction with colleagues at the office as i'm on the road the majority of the time and work independently. When ever I am there or need assistance my supervisor is always available to help.
The hours as I said are flexible, but, you still have to keep yourself motivated and diligent to completed and serve as many documents as possible. A thick skin is also required at times but for the most it is an enjoyable job as long as you have the right attitude.
