Pros
Good pay and benefits. Overall, it is a decent place to work if you do not have aspirations of advancing beyond the role you were hired for. During the recruiting process, they will tell you about examples of people who got promoted quickly. What they don't tell you is its only a handful of people who leave a trail of bodies in their wake to climb to the top to make face time with higher management.
Cons
This is a non-publically traded company owned by an Indian company. With this comes some politics of keeping the parent company happy. This company over the span of 4-5 years has seen many management changes. HR does not work for the employees but provides risk management to justify the firing of employees who were there before a particular management change and to justify the hiring of the incumbent management's friends and associates. Novelis is essentially where careers go to die.
