Legacy-flow maintenance, not greenfield
Every example is anchored in a real workflow engineers inherit — STA report parsers, netlist analyzers, regression dashboards, internal EDA utilities. Modern teams write new automation in Python; Perl is what they maintain.
Interview-ready for legacy teams
Tiered interview module plus per-chapter interview weighting — capture groups, context coercion, hash-of-hashes, legacy-script comprehension, and the migration questions every team with established Perl infrastructure asks.
Read → maintain → migrate
From the first regex to a 2000-line legacy regression driver, a per-corner STA report parser, and a Perl → Python migration plan — the full lifecycle every team with legacy EDA Perl eventually owns.
