    I have been working at ERRG (more than 3 years)


    ERRG gives its employees the opportunity to learn and grow. If you are motivated and a hard worker, ERRG will challenge you and foster your career growth. Senior management encourages staff to grow beyond their current job title and responsibilities. I have learned a lot at ERRG. I enjoy working with my co-workers at all levels of the company.

    I applied online. The process took 2 weeksinterviewed at ERRG.

    Interview Details

    I did an internship here so the process was probably a little different than usual but I had a phone interview followed by an in person. I first had a phone interview with someone from the department before having an in person interview with the CFO. He was a great guy and asked some questions about my educational background. There weren't any extremely technical questions (keep in mind it was an intern position).
