    I have been working at Nalco Water full-time (Less than a year)


    Great global organization with very talented and smart people. Lots of support from a corporate level.


    Every regional office is different. Not enough effecitve trainers to convey the information on to the next person.

    Advice to Management

    Its a lot of information to grasp on to at one. I had a trainer that was great at the job but horrible at teaching job responsibilities and technical knowledge. I suggest that trainers go through a training program before that are able to take on the task.

    Customer Service Representative Interview

    Anonymous Interview Candidate in Naperville, IL

    Negative Experience
    Difficult Interview


    I applied through a staffing agency. I interviewed at Nalco Water (Naperville, IL).


    Got interview through a temp agency and had to schedule twice since the manager had an emergency and had to wait for her to confirm the original interview only to not hear back until the next day and had to reschedule for a different day. Then was interviewed for the incorrect position - was supposed to be for a data Entry position and not this customer service rep one. But found out this one was a very structured position where you have timed breaks, lunches, etc. Interview was done by the manager and supervisor and asked situational questions... about it seems like 20. Then was asked if I had any questions that I thought that they should ask, but didn't. Of course I didn't have any after answering all of those and was semi ridiculed when I answered with a question about them instead.
    I contacted the temp agency Recuiter asking for an update ,after she said she would follow up with me when I told her I was interviewed for the customer service rep after the interview, but I haven't heard back from the Recuiter since then. **Update- the recruiter did get back to me and apparently the role was going to transition from one type to another. Either way- this was a bad experience on either the Recuiter or the manager's fault since there seemed to be a miscommunication or understanding of the role itself.
    I've had a good experience with Nalco before when I did a temp assignment with a cool manager and group , and thought this would lead to another positive experience , but guess not.
