Can either be a fun or stressful environment. It depends on the person. Most people are 50/50 on their answers
I worked here for 3 years and enjoyed my job. Towards the end, I didn't enjoy it as much as when I first started, because some of the managers had favorites and would put them over everyone else. The coworkers were nice, I met a TON of people and everyone is generally friendly. Very rarely, will you come across a rude coworker. If you have difficulty talking to people on the phone, I would recommend this job because it will help you get over that fear. I don't know why it was such an issue for me when I was younger, but after working here, I've developed better communication skills.
Undergrad student workers can either be a Level 1 or 1.5. Everyone starts off as a Level 1 and if you excel at your job, you may be promoted after at least 3 months I believe. There is only a $1 difference in the pay raise. Level 1's make $8/hr, while Level 1.5's make $9.
One thing to note is, if you're not a patient person, I wouldn't recommend this job. There will be many types of calls, from many different types of people and you can sometimes be on a call or even a chat, for an hour or more. As the customer, the last thing you want is someone with an attitude when you need assistance. Especially if you're someone who is computer illiterate, and the representative is trying to get you off the phone as quickly as possible, or hand you over to the next rep.
One last thing to remember is, they're open 7 days/week 362 days a year. The ONLY days they're closed is Thanksgiving Day, Christmas Day, and New Years Day. They also are open from 6am-midnight everyday, except on weekends, they're open from 7am-midnight.
