Pros

No pros as experience was worst.

Cons

The Reality of Working Here If you are a skilled Data Scientist looking for technical growth and merit-based advancement, look elsewhere. Over the last four years, the company culture has deteriorated significantly due to a lack of vision and skill at the upper management level. What was once a promising environment has shifted into a playground for internal politics and favoritism. Not recommended for someone whose an external hire and is not good at politics and flattery. Management & The "Lobby" System The workplace is governed by an internal lobby where bootlicking and flattery are the only true currencies for survival. Scapegoat Culture: Managers frequently target high-performing individuals to cover their own technical inadequacies. Sidelining: If you do not indulge in excessive flattery, you are systematically sidelined regardless of your output. Autocratic Style: Management is often unstructured and autocratic, making decisions based on personal bias rather than data or strategy. The Promotion Trap Career growth is virtually stagnant. Promotions are heavily influenced by favoritism rather than technical prowess. The Glass Ceiling: Senior management (G4) positions rarely vacate, and when they do, the company prefers external hires with personal connections. Performative Interviews: Internal candidates are often invited for interviews just to check a box, only to be sidelined for a pre-selected favorite. Specific Warnings for Data Science (ADS) I strongly advise against joining the Applied Data Science (ADS) side. * Zero Skill Development: Most roles involve redundant tasks that offer no room for professional growth. Biased Leadership: The directors and managers on this side are highly biased. Managers lack the spine to question directors and put the candidates feedback forward. Gender Bias: The current environment in these specific departments is notably unfavorable for male employees. Compensation & Final Verdict The salary offered is poor and does not align with industry standards, especially considering the toxic atmosphere. You will find yourself stuck in a high-stress, low-reward cycle where your career will plateau. Advice to Management: Upper management needs a complete overhaul. Stop promoting based on "loyalty" and start valuing technical expertise. Stop using your team members as scapegoats for your own lack of vision.
