        <h4>The weekly check in</h4>
        <p>Once a week during the first 90 days, a Density tech lead has a 30 minute private conversation with the engineer. Separate from your team. The goal is to surface friction your team doesn't see and resolve it before it becomes attrition.</p>

    <div class="embed-warning">
      <h4>Why we don't disappear after placement</h4>
      <p>Most providers treat placement as the deal closing. We treat it as the deal starting. The first 90 days are when bad placements show up, and most providers are not paying attention. We are. It is how we maintain our 100% success rate.</p>
