It had to be in testing, research and development, or quality control in a petroleum, petrochemical, polymer or fertilizer unit laboratory, or in a qualifying NABL-accredited chemical testing laboratory with the specified lubricant or petroleum-product scope. Academic teaching or research and short-term student projects did not qualify. Check the advertisement for the precise experience conditions before treating a borderline role as eligible.
Age
The maximum age for General and EWS applicants was 30 years as of 28 February 2025. The advertisement set out relaxations for eligible categories. The same 28 February 2025 cutoff applied to age, qualification and experience.

Indicative duties include testing fuels, petrochemical and polymer products, biofuels, lubricants and other samples; operating or calibrating laboratory instruments; testing samples and water or effluent; preparing records and certificates of analysis; maintaining laboratory quality systems; and following safety requirements.
