Pros

Good company with Good work culture Flexible timings for work and good culture.

Cons

Sometimes feel that the onsite German shepherd dog barks and dominates the Indian people. The work is once assigned in the project if that is not matching exactly with your role then you don't havea ny options to change that project and will suffer.

Pros

Strong exposure to core SAP Basis administration Access to large, complex global SAP landscapes Good opportunity to learn enterprise-level processes and controls Standardized documentation and compliance practices Brand name helps with resume credibility Suitable for gaining technical depth early or mid-career

Cons

Very weak people management; leadership quality varies widely Severe micromanagement with minimal trust in engineers Managers frequently intervene during live execution of activities High blame culture; accountability rarely owned by leadership Low psychological safety; engineers work in constant fear of mistakes Technical decisions often overridden for control, not quality Feedback is more corrective than constructive Growth, recognition, and experience depend heavily on the manager, not performance Stressful environment that can impact confidence and motivation Process exists, but empowerment is missing
