Hydraulics
Hydraulics is a way of moving and controlling machines using liquid (usually oil) under pressure. Think of it like a power system that uses fluid to lift heavy things, move machine parts, or control equipment. It's commonly used in construction equipment, manufacturing machines, and automated systems. When someone mentions hydraulics in their resume, they typically work with systems that use pumps, valves, and cylinders to make machines move or lift things. This is different from electrical or mechanical systems, though they often work together. It's similar to pneumatics, which uses air instead of liquid.

Example Interview Questions
Senior Level Questions
Q: How would you approach troubleshooting a complex hydraulic system that's showing intermittent pressure loss?
Expected Answer: A senior technician should describe a systematic approach: checking for leaks, testing pump performance, examining valve function, and using pressure gauges to isolate the problem. They should also mention documenting the process and training others.
Q: Tell me about a time you improved a hydraulic system's efficiency.
Expected Answer: Look for examples of system optimization, such as reducing energy consumption, improving maintenance schedules, or upgrading components. They should discuss cost savings and performance improvements.
Mid Level Questions
Q: What safety procedures do you follow when working with hydraulic systems?
Expected Answer: Should mention pressure relief before maintenance, checking for leaks safely, using proper lockout/tagout procedures, wearing appropriate safety gear, and following manufacturer guidelines.
Q: How do you read and interpret hydraulic system diagrams?
Expected Answer: Should explain understanding of basic symbols, ability to trace fluid flow paths, and experience with maintenance manuals and technical documentation.
Junior Level Questions
Q: What are the basic components of a hydraulic system?
Expected Answer: Should be able to identify and explain pumps, reservoirs, valves, cylinders, and basic maintenance requirements for each component.
Q: How do you perform basic maintenance on hydraulic equipment?
Expected Answer: Should describe checking fluid levels, changing filters, inspecting for leaks, and basic preventive maintenance tasks.
