Quantify in the units this charter respects
Compare two rows from "Quantify in the units this charter respects", then say when each one fits.
Step 1 of 2
Quantify in the units this charter respects
- Weak result
- "Improved GPU efficiency"
- TPM-grade result
- "Lifted sustained utilization on the shared GPU pool from about 22% to about 48%, roughly $2M a year"
- Weak result
- "Helped with cost attribution"
- TPM-grade result
- "Stood up cost-per-active-user tracking that resolved 90% of spend to a product within one quarter"
- Weak result
- "Ran the capacity planning"
- TPM-grade result
- "Built the demand model that tied GPU need to DAU growth; the next-quarter forecast held within 8%"
- Weak result
- "Drove the migration"
- TPM-grade result
- "Sequenced the inference-cluster migration across 4 teams with zero SLA breach, on the committed date"
| Weak result | TPM-grade result |
|---|---|
| "Improved GPU efficiency" | "Lifted sustained utilization on the shared GPU pool from about 22% to about 48%, roughly $2M a year" |
| "Helped with cost attribution" | "Stood up cost-per-active-user tracking that resolved 90% of spend to a product within one quarter" |
| "Ran the capacity planning" | "Built the demand model that tied GPU need to DAU growth; the next-quarter forecast held within 8%" |
| "Drove the migration" | "Sequenced the inference-cluster migration across 4 teams with zero SLA breach, on the committed date" |
Illustrative numbers. Replace adjectives with a number and the unit: $/yr, utilization %, forecast error %, SLA breaches.
Prepare two stories that mirror the posting's requirements. One "I influenced senior technical leaders to commit to a plan I couldn't mandate" story covers influence without authority. One "I built the model myself and the model changed the decision" story covers action bias plus altitude. If you only prep one, prep the influence story, because the posting asks for exactly that.
"We lifted sustained utilization on our shared GPU pool from about 22% to about 48% in a quarter, roughly $2M a year. The hard part was the setup: three teams shared the pool, none of them reported to me and each assumed another team was the wasteful one. So I built the attribution model that showed where the idle hours actually sat, brought it to a weekly review I ran and let the data settle the argument instead of me. The ML leads owned the model-routing change that did most of the work. I owned getting them to agree on the split and holding everyone to it. If I redid it, I'd have instrumented per-team utilization a month earlier, because we argued from anecdotes for too long before the data existed."

Two things sink a TPM story. An all-"we" narrative hides your contribution, so the interviewer can't find you in it. A humblebrag failure, such as "my weakness is I care too much about accuracy," is the other. Keep one genuine failure where a program slipped or a forecast was wrong and land it on the real lesson, not a disguised strength.
