When hiring, top firms like McKinsey value a candidate's ability to articulate a deliberate, logical problem-solving process as much as their past successes. Having a structured method shows you can reliably tackle novel challenges, whereas simply pointing to past wins might suggest luck or context-specific success.

Instead of just sending a resume, prove your value upfront by delivering something tangible and useful. This could be a report on a website bug, an analysis of API documentation, or a suggested performance improvement. This 'helping' act immediately shifts the dynamic from applicant to proactive contributor.

To accelerate your career, focus on developing 'agency'. This means moving beyond assigned tasks to proactively solve unspoken, systemic problems. Instead of chasing high-visibility projects, look for the unaddressed issues that keep leaders up at night. Solving these demonstrates true ownership and strategic value.

Employees who strictly adhere to their job description are likely to remain in the same role for years. Going above and beyond, such as cleaning a boss's station to simply be in their orbit, builds a reputation and relationships that lead to unexpected opportunities.

Rachel Andrews's journey from planning Cvent's holiday party to Global Head of Events shows that growth comes from executing every small opportunity flawlessly. This hunger to "do more" demonstrates capability and opens doors to greater responsibility, rather than waiting for big, impressive projects to fall in your lap.

Diller advises against rigid, long-term career goals like "running a studio." He argues that focusing intensely on your current role creates natural momentum. The "sparks you set off" will impress others and pull you into your next opportunity, making deliberate networking or goal-setting unnecessary.

The most impactful career advice is to focus on becoming world-class in your innate strengths rather than trying to become mediocre in areas of weakness. It's more effective to elevate a core skill to an 'A' grade than to struggle to raise a weakness from a 'D' to a 'B'.

Don't wait for a promotion or new job opening to grow. Proactively identify other teams' pain points and offer your expertise to help solve them. This proactive helpfulness builds relationships, demonstrates your value across the organization, and organically opens doors to new skills and responsibilities.

For early-career professionals, success isn't just about task mastery. It's about understanding how your specific role contributes to the firm's broader commercial engine. This holistic view allows you to spot opportunities and develop a unique, value-added perspective on solving client problems.
