Stockmark scores B on the Alion truth index (A is best, E worst), measured over 15 open roles re-checked against its own hiring board: 20% look like ghost listings, 0% have gone stale and 0% are the same role posted again. Its roles close in a median of 134 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
