The pay was good for a summer job, and the work environment was generally positive and constructive (besides some management).
What I wish was different
Occasionally, management will expect far more than what you're capable of handling during times of exceptionally high call volume. I'd find myself giving 100% effort with practically zero downtime and still receiving backlash.
Advice
One piece of advice would be to expose yourself to customer interaction as soon as possible because it's the fastest way to pick up on the work (and how to navigate constructive customer interactions).
