Walk me through your first 30, 60, and 90 days in a new customer-facing engineering role.

The graded shape is specific: learn and ship something small by day 30, own a deployment by day 60, drive a cross-customer improvement by day 90. Vague answers about 'meeting stakeholders and ramping up' fail. Here is the staged plan with what good looks like at each gate.

FEDITOR'S NOTE

Interviewers have a rubric in mind for this one: 1-30 = learn the product and ship a small, real customer win; 31-60 = own a deployment end-to-end and leave behind something reusable; 61-90 = drive an improvement from field data that helps more than one customer. The answer that sounds good but fails is the passive ramp ('shadow the team, read the docs, build relationships') with no shipped artifact by day 30. The held-back follow-up is 'what if you're blocked the whole first month', and they want to see you ship something small anyway rather than wait for access.
