India
The business leaders I have worked with most closely all say a version of the same thing: "You were the one person I could be honest with." Building that kind of trust — quickly, consistently, across different organisations and cultures — is what my career has been about. I am Siidarth Bhattacharya. I work as a Senior HR Business Partner and people strategy professional, partnering with business leaders to make better decisions about the people who run their organisations. Over two decades, I have done this at Comcast (Fortune 30, India GCC), Flipkart-Walmart, Hyundai Motor India, and DXC Technology — and more recently with founders at Series A-to-C Startup organisations across India, UAE, and Singapore. A few things I have been part of: — Supported one of India's fastest supply-chain workforce ramp-ups at Flipkart-Walmart — surge staffing, onboarding redesign, IR management, and early attrition interventions, with zero IR disruption — Contributed to sustained employee engagement improvement at Comcast India — EVP-linked listening programmes, manager capability building, and pulse surveys alongside the India MD and global HR leadership — Partnered on a large post-merger people integration at DXC Technology — policy harmonisation, leadership transitions, and workforce stability through complex organisational change, delivered ahead of schedule — Helped reduce voluntary attrition through stay interviews, predictive attrition modelling, and targeted retention for critical-skill employees — Served as the primary people strategy partner to Engineering, Product, and Operations leadership India GCC — workforce planning, headcount governance, org design, and talent decisions aligned directly to business unit goals, across a multi-geography team My core work spans strategic HRBP, workforce planning, org design, talent management, succession planning, 9-box calibration, leadership pipeline, and L&D strategy. On the operational side: total rewards, M&A HR integration, HR shared services, Hire-to-Retire, change management, people analytics, DE&I, POSH, labour law, and statutory compliance. Technology: Workday HCM, Darwinbox, Keka, BambooHR, SucessFactor, Microsoft Viva Insights, and AI-enabled HR tools. Registered patents in predictive workforce analytics and AI-assisted talent systems. The best people work is nearly invisible — attrition falls quietly, leaders grow steadily, and organisations become a little more resilient every year. If something here resonates — whether to connect, collaborate, or simply exchange ideas — I would genuinely welcome it.
