What Working at Big Tech Is Actually Like: An Honest Guide for New Grads

Short summary

Working at a Big Tech company differs fundamentally from student projects: you join existing systems at scale where architecture is already decided. Internal tools replace familiar open-source stacks, debugging becomes investigative across teams you haven't met, and much of the job is holding context that lives in people rather than docs. The discomfort of relearning familiar concepts is normal and temporary.

• •You work within existing architecture, not from a blank page — design decisions are local, not global
• •Internal tools replace open-source equivalents; concepts transfer but specifics must be relearned
• •Senior engineering at scale is largely about holding context and finding the right people, not just reading code
