A fictional resume written by our team. The person, employers and numbers are invented; the tools, licenses and schools are real.

Why it works

  1. 1

    “Data engineer with 10 years in analytics and data platforms, the last 4 leading pipeline work for an online grocery company. Own a Snowflake and dbt platform of about 1,100 models from 70 sources, used by 400 people.”

    Years, stack, scale and who depends on the work. A hiring manager can place the level of this engineer from two sentences.

  2. 2

    “Own a Snowflake platform of about 1,100 dbt models from 70 sources via Fivetran and Kafka, used by 400 people”

    Scale and stack in one line: models, sources, how data comes in and who relies on it.

  3. 3

    “Moved 45 nightly batch jobs to incremental dbt models, cutting the daily load from 5 hours to 65 minutes”

    A runtime before and after with the number of jobs. Faster loads mean fresher data for everyone downstream.

  4. 4

    “Met a 7am freshness SLA on 99.2% of days in 2025 for the finance and operations dashboards”

    A reliability number tied to the people it serves. Data teams are judged on whether the numbers show up on time.

  5. 5

    “Rewrote 20 legacy SQL Server ETL jobs in Python and Airflow on AWS, retiring 3 on-prem servers”

    A migration with a count and something switched off at the end, which shows the work actually finished.

How it scored

B+

8
Buzzword score out of 100, lower is better

We ran this example through the same free roast you can use, three times, and kept the middle result. The roast ranks a resume against a typical applicant pile and grades hard: even a resume with a number in nearly every bullet usually lands in the B range.

Copy the text

Use it as a skeleton, then replace every line with your own work. A copied bullet with someone else's numbers is the fastest way to fail an interview question.
