How datainterview.org checks its sources

Quotations: 125
Organizations: 18
Practice interviews: 5
Sources checked: Nov 11, 2026

What is real

Every quotation is copied from the organization’s own publication and links to it. The site’s build compares each one, word for word, with a saved excerpt of that page, and fails if a word differs.

Checked against the published text.
A date appears only when the publisher states one. The day we checked a page is never shown as its publication date.
No organization quoted here endorses this site or reviewed it.

What is invented

The practice interviews are original. Waymark and every number, record and person in them are fictional. They are not any employer’s real interview questions.

Who publishes this

Socratify AI publishes and sponsors datainterview.org. Links to Socratify are marked as sponsored. Send a correction to hello@socratify.com.

Without offline-online signal calibration, our evals are opinions, not evidence.Matilda Ankargren and Mårten Schultzberg, Senior Data Scientist; Senior Manager/Staff Data Scientist. Better Experiments with LLM Evals — A funnel, not a fork, May 18, 2026.
the setting in which LLMs offer the most benefit for A/B testing is precisely where they are least likely to work. Human experiments therefore remain indispensable for true product innovation.Sebastian Ankargren, Joel Persson and Mårten Schultzberg, Senior Data Scientist; Research Scientist, Computational Economics; Senior Manager, Staff Data Scientist.
