It is on the interval scale.
Occupation is nominal data. There is not an order to the category occupation, so that eliminates ordinal and interval.
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
nominal
ratio
The IQ scale is considered interval because the differences between scores are standardized and consistent across the range of scores. This means that a difference of 10 points on the IQ scale represents the same change in intelligence level regardless of where on the scale it occurs.

IQ (Intelligence Quotient) is considered interval-level data. This means that IQ scores have a meaningful order and the differences between scores are consistent and quantifiable, allowing for comparisons between individuals. However, IQ scores do not have a true zero point, meaning that a score of zero does not indicate the absence of intelligence, which is a characteristic of ratio-level data.
Occupation is nominal data. There is not an order to the category occupation, so that eliminates ordinal and interval.
