Chemical Engineering Test Preparation: Practice Questions, FE Exam Topics, and Interview Prep
The Job Tests Portal Chemical Engineering Test covers the four core areas screened in chemical and process-engineering interviews: thermodynamics, reaction engineering, mass transfer and separations, and process control with safety systems. The bank holds 70+ multiple-choice questions at advanced level, a full run takes about 35 minutes, and every answer includes a step-by-step explanation. One worked sample question is free below.

Chemical Engineering Test: Format and Difficulty
Topic coverage follows the NCEES FE Chemical specification areas - material and energy balances, fluids, thermodynamics, heat and mass transfer, reaction engineering, and process design and control - at survey depth, matching how those topics appear in university curricula and employer screens.
Which Chemical Engineering Topics Are Tested?
Master these essential areas that employers actively seek
Thermodynamics
Heat transfer, phase equilibria, energy balances
Reaction Engineering
Kinetics, reactor design, conversion calculations
Mass Transfer
Distillation, absorption, extraction processes
Process Control
PID control, instrumentation, safety systems

How to Pass a Chemical Engineering Technical Assessment
Master material and energy balance fundamentals - they anchor every screen
Practice unit conversions relentlessly; they are the most common error source
Review safety data sheets and hazard classifications
Understand common industrial processes (distillation, absorption, reactors) end to end
Sketch the process flow before calculating - it exposes missing streams
Check answer magnitudes; distractors are usually off by a factor of ten

Free sample question - Process fundamentals — worked solution included, no sign-up needed
A process stream flows at 120 L/min. What is the flow rate in m³/h?
Show answer and explanation
Correct answer: B. 7.2 m³/h
120 L/min × 60 min/h = 7200 L/h, and 7200 L/h ÷ 1000 L/m³ = 7.2 m³/h. Flow-rate unit conversion is the opening move of most material-balance problems, which is why it appears in nearly every chemical-engineering screen.
Who Uses Chemical Engineering Technical Assessments?
Process-industry employers screen chemical engineers with technical assessments before or alongside interviews. Oil and gas companies such as Shell, BP, and ExxonMobil test material balances, thermodynamics, and process safety; chemical producers such as BASF, Dow, DuPont, and LyondellBasell add reaction engineering and separations questions for process-development roles.
Engineering consultancies such as Atkins and Jacobs assess the same fundamentals for design roles, and pharmaceutical and food-process employers (AstraZeneca, GSK, Nestlé) screen for unit operations and GMP-aware process thinking. The question style here - short numerical problems with clean answer options - mirrors what those first-round online screens use.
Chemical Engineering Test FAQ
Four core areas: Thermodynamics (heat transfer, phase equilibria, energy balances), Reaction Engineering (kinetics, reactor design, conversion), Mass Transfer (distillation, absorption, extraction), and Process Control (PID loops, instrumentation, safety systems). The bank holds 70+ multiple-choice questions at advanced difficulty.
Topic coverage follows the NCEES FE Chemical specification areas - material and energy balances, fluids, thermodynamics, heat and mass transfer, reaction engineering, and process design and control - at survey depth, so it works as topic-level practice alongside a dedicated FE course.
A full run is designed for about 35 minutes. You can focus on a single area (thermodynamics, reactions, separations, or control) or take the full bank, and each answer includes an AI-generated step-by-step explanation.
Shell, BP, ExxonMobil, BASF, Dow, DuPont, and LyondellBasell include technical screening in chemical-engineering hiring, as do design consultancies such as Atkins and Jacobs. Screens typically cover material balances, thermodynamics, and process safety fundamentals.
Yes - the worked sample question on this page is free, no sign-up needed. The full 70+ question bank with explanations and progress tracking starts at $3.99 for 30 days of access.
Common reference equations are provided within questions, similar to how professional exams supply a reference handbook. You should still memorize the core relationships - they appear in interviews without references.
