What is a T-shaped skill set?

Deep expertise (vertical bar) in one domain, plus intermediate knowledge (horizontal bar) in multiple adjacent areas. Creates unique value.

Why do employers value T-shaped people?

They solve problems across boundaries. Less siloed thinking. Mentor across teams. Translate between domains. Adapt to new roles faster.

Master one domain to advanced level. Learn 3-5 adjacent fields to intermediate. Practice integrating across domains. Seek cross-functional projects.

T-shaped: one core expertise. M-shaped: two core expertises. M-shaped is rarer but more valuable; requires more time to develop.
