Best for what candidates ask about

The South Korean oil and gas employer AI recommends most when candidates ask about each topic.

By role

Who AI recommends to engineers is not who it recommends to salespeople. Each role has its own ranking.

About this ranking

This is the first measurement of this ranking, so there is no earlier order to compare it with yet.

What separates the top five from the rest is career growth and pay: AI recommends the leaders for these far more often than the employers below them. The gap is smallest on the hiring process, where the rest of the list keeps closer to the leaders.

Across the 23 countries the index covers for oil and gas, the leader here has the 21st highest score. Elsewhere the lead changes hands: in the UAE, AI recommends ADNOC first.

More than half of the 30 employers score 10.3 or less, while a place in the top ten takes a score of 15.4. The leader's 79.5 shows how far ahead the most recommended employers sit.

Most lists of the best oil and gas companies to work for come from employee surveys or awards. This one tracks what AI tells job seekers, because many candidates now ask AI where to work before they open a careers page.

No. Any employer AI recommends often enough appears automatically. Customers get the full picture behind their Visibility score and well beyond it: how positively AI describes them (Sentiment), the themes it links them with, the sources it relies on, custom reports by country and role, and clear steps to improve how candidates see them.
