Are vendor certifications less important than strong computing fundamentals?

In general, strong fundamentals—such as algorithms, data structures, operating systems, networking, and databases—and the ability to apply them to solve problems are more important in the long term than vendor certifications. However, certifications can help demonstrate knowledge of a particular product or provide a structured learning goal, so they are not necessarily substitutes for fundamentals. Building fundamentals first and then choosing certifications related to a target role is often a sensible approach.
