What is “good taste” in software engineering?

You can be technically strong but have poor taste, or technically weak with excellent taste. Engineers must balance competing priorities like speed vs. readability, correctness vs. flexibility, and scalability vs. development speed. Good taste means selecting values that fit your specific context rather than rigidly applying universal "best practices."

While DSA helps with interviews, real software engineering rarely involves implementing sorting algorithms or balancing trees. Testing skills stand out more to employers and actually get used daily on the job.
