The Orders Pipeline: Clean, Dedupe, Load
How it works
Pick a challenge
A realistic business task with its own data, sized for freshers: one scenario, 45 minutes.
Build and submit
Your private repo opens in a browser workspace. Run sample tests, submit up to 3 times; your best counts.
Defend your work
Pass the hidden tests and a 15-minute interview asks about your own code, plus one live change.
Get ranked
Task (60) plus interview (40) makes your score out of 100, ranked per challenge, sub-domain and domain.
What makes a Vouch score different
Anyone can list skills. A Vouch score says you built a working pipeline against hidden tests, then explained it to an interviewer who had read your code.
- Every attempt gets its own dataset, so answers can't be shared.
- Hidden tests check correctness, data quality, re-runs and scale, not keywords.
- Paying for a retry or a certificate never buys a higher score.
