How to get hired
Continuous plants or batch plants: choose knowingly
Continuous plants (refineries, petrochemicals, fertilisers, chlor-alkali, cement) run for years between shutdowns. You join as a GET or shift engineer, learn the unit from the field first, then move to the control room panel. Batch plants (pharma APIs, agrochemicals, dyes, specialty and fine chemicals) run many products through reactors in campaigns; you handle batch records, yield, solvent recovery and scale-up from the R&D lab. Batch plants hire more freshers, more often and off campus; continuous plants pay better at the start and are harder to enter.
The chemical belts where most of these plants sit: Vapi, Ankleshwar, Dahej, Bharuch and Jamnagar in Gujarat; Taloja, Tarapur and Mahad in Maharashtra; Hyderabad and Visakhapatnam pharma zones; Panipat, Mathura, Haldia and Kochi around refineries. Be ready to live there.
What plant interviews test
Mass and energy balances, heat exchanger basics (LMTD, fouling), distillation (reflux ratio, flooding, what happens when the reboiler duty drops), pump cavitation and NPSH, and reaction engineering for batch roles. Safety comes up in every interview: what HAZOP is, what a permit to work covers, why you never open a line without isolation and draining. Say how you would respond to a pressure rise in a reactor before you discuss yield.
Process design and EPC
Process engineers in EPC and consulting firms size equipment, develop PFDs and P&IDs, write datasheets and run simulations in Aspen HYSYS or Aspen Plus. These roles prefer campus hires from strong colleges or an M.Tech, and they reward engineers who did two or three years in a plant first, because they know what works on site.
GATE CH and PSUs
Refining, gas and fertiliser PSUs recruit chemical engineers on GATE Chemical Engineering (CH) scores, followed by group discussion or interview. GATE 2027 runs in February 2027 under IIT Madras. Each PSU notice sets its cut-off, age limit, reservation and service bond, and the bonds can be substantial; see our job bond guide and government exams basics.
Other doors
- NATS graduate apprenticeship at a chemical or pharma plant: a minimum ₹12,300 a month from April 2026, half paid by the government; register on the NATS portal
- Environment and water roles (ETP, STP, ZLD plant operation and design), which overlap with the HSE guide
- Technical sales and service for equipment, catalysts and chemicals, for engineers who like customers
- Boiler Operation Engineer certification later in your career, if you run utilities
First titles: GET – Process, Shift Engineer, Production Engineer, Trainee Officer – Production (pharma), Process Engineer, Engineer – Technical Services.
Control rooms, campaigns and the unit-head ladder
You will spend your first years on rotating shifts. In a continuous plant that means field rounds, sampling, handing over to the next shift and learning to read the DCS trends; the quiet nights are long and the bad ones are frightening. In batch plants the pace is faster, with charging, sampling and transfers through the night, and documentation that auditors will read. Planned turnarounds mean weeks of twelve-hour days.
The ladder: GET or Trainee, Shift Engineer, Senior Engineer or Shift In-charge, Assistant Manager – Production or Process, Unit Manager or Section Head, then Plant Manager. The big pay jumps come with a move into technical services, process design or a larger continuous-process company, and at the unit head stage. Experienced refinery and petrochemical engineers are recruited by Gulf operators.
