Ventajas
The job is simple enough. There is a large investment in in new hires through training, leadership opportunities, and proactive coaching. Most Applications Engineers come right out of college so there are many people the same age; easy to make friends. There is significant emphasis placed on connecting business goals with day-to-day activities.
Desventajas
You are a customer support representative. There are some days when I get to use my engineering degree but they are few and far between. The work is not very rewarding and it can takes upwards of 3 years to move into a position you will actually enjoy such as marketing or R&D. This is a feeder into the rest of the company and is treated like a minor/easy job. The management is chosen directly from this group and is thus inexperienced and constantly changing.
