<li>
</li></ul> 
<h2 class="jobSectionHeader">What Good Looks Like
</h2>A strong candidate can describe systems they owned, incidents they handled, trade-offs they made, and mistakes they learned from.
They should be able to explain how they approach unclear problems, reduce risk before production, and make systems easier for the team to operate.
They should not need a tech lead to turn every ambiguous problem into a detailed task list.
