Svantaggi
Professional Service in Oracle has limited career upside. Unless you are at HQ, or have ability to network extensively with managers (higher ups) you will not have any visibility. This is especially true for field consultants, no relationship with others except via email and occasional vmail with your practice manager. Also, consulting model within Oracle is moving to offshore/onshore where majority of consultants are remote-based, or imported on a rotational basis into US for work. This means that the US based consultants reduced to team lead aspects, with majority of consultants from overseas oracle divisions.
