SHI is an amazing place to begin your professional career from college. The management and overall sales training are elite. SHI truly knows what it's doing in terms of grooming salesman and growing the business.
SHI is growing at a rapid pace so that opens up opportunities for advancement into management.
The hardest part is the monotony but I feel that's with every corporate job. SHI had done a great job in the past by offering multiple gatherings, functions, and awards. To take employees minds off the stress of the job. I feel a few employees got carried away and SHI has cut back drastically on the "extracurricular" portion. There is a significant culture change going on with SHI and I will say for old employees it's not an issue. However, for new employees that aren't necessarily making money just yet. It's stressing them out quicker and creating a rotating door affect.
Overall SHI isn't perfect but it's pretty close. A great stepping stone for sales if it works out for you there. Give SHI 2 years you'll either have been promoted, created a solid book of business, or moved laterally to a different role. If none of that has happened use the experience and training you gained there to move to the next opportunity.
