Working at NRG research was one of the best decisions I have made, though a small company, they provided you with the tools you needed to start in an office environment. The management team are very professional and will help you with any questions you had. With my experience, I learned how to communicate over the phone with others. Though we were not selling or advertising anything, majority of the time we tend to deal with people who think we're telemarketers. They will teach you rebuttals and what you need to tell them to accomplish your job.
Hours, Just like some companies, there are days, weeks or months where there is not enough work, so there will be times where your shifts might be cancelled. This is why I would advise to keep this job as part time, and not to really depend it on your only source of income. ( if living alone) However if you are one of the few who do their job well, you might be one of the lucky ones chosen to work during the day projects which will provide you with a full 8 hour shift.
All in all, NRG research is a good place to start if your coming straight from school, need a part time job or extra income. You will gain experience and develop if not a lot but some confidence in an office environment. There some is room to grow within the company, and incentives
not enough hours at times
