Pros
There are no pros .you will end up ruining your career.
Cons
1.legacy technologies. 2.interviewer kept telling me they work on spring boot and in reality the project is in spring MVC with soap web services. 3.all projects are in old technologies but they lie to you while taking interviews. 4.Do not just go with "Simens" name,they are ruining careers of techies by making them work on legacy technologies. 5.No value for technical expertise you bring,you should keep buttering people and take part in nonsense meetings to get promotion. 6.I do not find Siemens Energy as technology company from any angle.all they are running is management school where everyone wants to become manager and do not want to do development work. 7.Join only if you want to ruin your career and end up being frustrated every single day. 8.There is no place for talented people in Siemens Energy.if you are good at buttering,this is best place for you.
