Ventajas
Job security is really good. Almost comically hard to fire someone. Pretty good tuition reimbursement policy. Able to work and get masters part time on the companies dime. Good place to learn basic data science skills. Companies 9/80 policy means you work longer days but get every 10th day off (translation every other friday)
Desventajas
Very much still an engineering company so while it is a good place to learn the basics, there is a lack of advanced projects for employees in Sikorsky's analytics organization to work on. After working in the analytics organization at Sikorsky in CT, I have worked for 2.5 years and have had 4 different managers in the group. There is extremely high turnover due to lack of group making big measurable impact on the company. As a result most people learn a good skill set on the companies dime and then go use it to make an impact in a different area. Very much an old mans company. Obviously this comes down to the group you are placed in but for the most part the average age is on the older side. The particular group I am placed in is sort of like a mission control. Open seating means no cubicles. This is great when you are learning because you can easily ask a lot of questions, but once you know what you're doing distractions become annoying.
