Vantaggi
Nothing. My biggest mistake was to join this organization. Example for worst worst middle management. Example - in Apollo core platform team where I worked. Director left because he hated the company and since they were not able to find replacement, company promotes the engineering manager as IT director of group and that follows a promotion of inexperienced engineer to become manager. Selection criteria was that they were with the company for more then 2 years and were friends of upper management person. How easy! was that to screw life of all good engineers like me who were working under these non-eligible candidates. Later the entire team leaves.
Svantaggi
Everything, stay away from Apollo. People staying(left-over) are mostly managers who cant find same position else where(off-course they cant) or engineers who are struggling with interviews conducted by other companies.
