Depth beats breadth: what actually gets screened

It is tempting to collect every skill and tool on the list, but a Data Engineer gets shortlisted on depth in a few core areas, not a shallow tour of everything. Hiring managers can tell within minutes whether you have actually used a skill in anger or just watched someone explain it.

Pick the two or three skills at the top of the list above and go deep enough to defend your decisions, explain your trade-offs, and show real work where you used them. Breadth comes naturally with time on the job. The way you prove depth is not a certificate, it is a portfolio piece and, better still, verified experience where you applied the skill on a real problem.
