The people-focused approach extends to flexible working arrangements and strong internal networks that support work-life integration. Many professionals appreciate the emphasis on well-being and inclusive leadership initiatives.
If your interests span risk advisory, strategy, or transformation consulting, EY’s transaction experience and consulting capabilities provide a platform to work on complex, cross-functional initiatives across industries.

The firm tends to have a team-based culture with steady workloads, which can be appealing if you prefer predictable schedules and stronger peer collaboration over hyper-competitive environments.
Regional variation is more pronounced at KPMG, so your experience may differ depending on the country or city, but the emphasis on risk and internal processes can translate into highly transferable skills in governance and assurance.
