Engineering and manufacturing assessment tests for hiring

What engineering and manufacturing tests cover

The 12 tests cover software, technical knowledge and practical judgment across engineering and manufacturing work. For drawing and modeling, AutoCAD measures precise input, 2D geometry, drawing organization and output, and 3D solid modeling. Autodesk Revit focuses on modeling, documenting, coordinating and setting up building projects, while SolidWorks covers parts, assemblies, production-ready design and analysis tools. SketchUp Pro assesses 3D modeling, solid geometry, complex shapes and model organization.

Other tests address machining and technical drawings. CNC Machinist (Imperial Measurements) measures G-code in inch units, machine setup and operation, and machining sequence. Geometric Dimensioning & Tolerancing (GD&T) covers callout symbols and modifiers, datum reference frames, and tolerance types and zones.

Other tests cover the trades and the site. Equipment Maintenance covers mechanical, hydraulic, pneumatic and electrical maintenance on heavy equipment, and HVAC (Heating, Ventilation, and Air Conditioning) covers keeping chillers, air distribution and air conditioners running. Fundamentals of Electricity covers basic principles, circuits, digital logic and power. GHS Safety covers reading chemical labels and safety data sheets, and Construction Management covers project controls, site logistics and contracts. Mechanical Reasoning measures understanding of forces, motion and how gears, pulleys and wheels move. Each test takes 10 minutes. All use multiple choice; Mechanical Reasoning also offers picture choice.

Choose tests by role and level

All tests are intermediate except Fundamentals of Electricity, which is entry level. It suits entry-level electrical roles such as electrician helpers and apprentices, line installers and repairers, and equipment service staff. For hands-on maintenance roles, Equipment Maintenance covers heavy-equipment systems and inspections, while HVAC (Heating, Ventilation, and Air Conditioning) assesses keeping HVAC equipment running and diagnosing faults from readings.

For CAD and design roles, choose based on the software and work involved: AutoCAD suits people who produce or maintain CAD drawings, Revit suits people who build or manage Revit models, and SketchUp Pro suits roles that build 3D models in that software. SolidWorks is aimed at people who build or review its models. GD&T fits engineers, drafters and inspectors who work with mechanical drawings.

For production work, CNC Machinist (Imperial Measurements) is for machinists and operators moving into setup or programming who work with inch drawings. GHS Safety is relevant to roles that handle hazardous chemicals. Construction Management suits project and site management roles on building and civil projects. Mechanical Reasoning can add evidence for hands-on technical roles, engineering trainees and facility engineers.

Combine assessments around the work

Use the responsibilities of the role to select complementary evidence rather than giving every applicant the full set. For a CAD technician who maintains drawings, pair AutoCAD with GD&T if reading geometric callouts is part of the job. For someone who builds mechanical models in SolidWorks, combine that software test with GD&T when drawing interpretation is also relevant.

For a heavy equipment or plant maintenance technician, pair Equipment Maintenance with Mechanical Reasoning, whose listed roles include maintenance technicians and machine operators. Mechanical Reasoning also lists HVAC trades, so it can sit beside the HVAC test for a service technician. Fundamentals of Electricity is the one entry-level test; for an electrician helper or apprentice, Mechanical Reasoning can add evidence on forces and motion.

For a machinist who works from inch drawings, CNC Machinist (Imperial Measurements) can be paired with Mechanical Reasoning, which also lists machinists and machine operators. For plant maintenance staff who handle hazardous chemicals, GHS Safety can sit beside Equipment Maintenance. Construction Management focuses on project controls, site logistics, contracts, procurement and stakeholder management, so it is a distinct choice for building and civil project roles.

Review each score as evidence about the skills that test measures. Consider it alongside the role requirements and other information gathered in hiring. A score is not a verdict or a substitute for a person’s review.

Fairness and score review

The tests use different approaches to reduce reliance on details unrelated to their stated subject. AutoCAD questions name commands and describe actions rather than relying on a particular ribbon layout or screen size. Revit questions describe models in words and small tables, not release-specific screenshots or shortcut locations. SolidWorks also uses words and small tables rather than screen layouts, and limits features to those that behave the same in recent releases.

Several tests provide the information needed to answer instead of assuming local practice or memorized reference material. CNC Machinist questions show any needed charts and use common ISO-style code. Equipment Maintenance states the relevant specifications and limits. GHS Safety gives the label, data sheet excerpt or site rule a question relies on. HVAC supplies needed pressure-temperature values. Fundamentals of Electricity states needed values, including supply voltage, and describes circuits in words and tables.

Other design choices are specific to the test. Construction Management uses widely taught practice rather than one country’s codes, laws or standard contracts. GD&T uses ASME Y14.5-2018 terms and symbols, with characteristics named in words beside symbols. Mechanical Reasoning uses simple drawings and plain sentences, with parts distinguished by letters and shapes rather than color. CNC Machinist and Fundamentals of Electricity give every candidate an on-screen calculator and scratch paper, while Construction Management and SolidWorks keep numbers simple enough to work without one. GHS Safety checks knowledge and does not replace a site's own chemical safety training. For accommodations, see Fairness and accommodations.
