Pros
SK has really good benefits (401K, good salary especially for young people, health insurance, flex PTO, etc), and the hours are very consistent. This is not the type of job where you work late hours, you will always clock off at your set end time. Although very repetitive, the work is not hard at all. They require the designers to have a degree but honestly anyone could do this job. If you are looking for a good paying , stable job, and you don't necessarily care about the actual work you are doing (basically just want to collect a check and go home) this is a very good choice for that.
Cons
The work is the same every day, it never changes. Especially for designers, this can get very old very quickly, and management does not like when you express interest in pursuing other responsibilities outside of your expected work. Be sure to triple check with management what is expected of you, because there was a lot of inconsistencies with communication. The designer job in particular is less of a design role and more of a "how well can you use Photoshop" type of job. You will use pre-made templates every day, and rarely get the chance to create work from scratch. Also, there is no art or creative director who manages the design team, so if you are looking for creative direction you will not find that here. The other designers will give you feedback at times but on a daily basis you are on your own. It is not the most fulfilling role creatively, so if you are looking for a job where you can grow as a creative, it will be hard to do so here.
