Motion Control Engineer Interview Guide
Motion Control Engineering is a discipline where the Netherlands leads the world. ASML's wafer stages achieve nanometre-level positioning while accelerating at tens of G — and the engineers behind that capability are in extremely short supply. Whether you work on semiconductor equipment, robotics, or medical devices, a well-constructed CV is your entry point.

What hiring managers look for
Control system design: PID, state-space, model predictive control (MPC), or feedforward/feedback architectures
Modelling and simulation: Matlab/Simulink, 20-sim, or equivalent — from first-principles to validated models
Real-time implementation: experience deploying controllers on DSPs, FPGAs, or real-time OS platforms
System identification: experimental methods for characterising plant dynamics (frequency response, step response)
Performance specification and verification: bandwidth, settling time, tracking error, disturbance rejection
Mechanical understanding: resonance modes, stiffness, damping — the interface between controls and mechanics
Top priorities for this role
What hiring managers rank highest when screening Motion Control Engineer candidates.
Control theory fundamentals — can you explain what happens in a servo loop when you increase the integral gain?
Physical hardware experience — tuning in simulation is different from tuning on a machine that is shaking
Mechatronics integration — motion control engineers must understand mechanical resonances, motor characteristics, and actuator limitations
Real-time system expertise — motion control runs on deterministic real-time systems with microsecond cycles
Performance analysis — can you measure, diagnose, and prove improvement in servo performance?
Common interview mistakes
Describing control designs without performance numbers: a "well-tuned PID" means nothing without specs
No mention of the hardware platform: motion controllers, drives, amplifiers (dSpace, Beckhoff, National Instruments)
Omitting the disturbance and noise environment — precision motion context requires this
Academic simulation-only experience presented as equivalent to physical system commissioning
Likely interview questions
Questions hiring managers commonly ask for Motion Control Engineer roles in the Netherlands. Prepare concrete examples using the STAR method.
Q1
Explain the purpose of the P, I, and D gains in a servo position controller. What does increasing each one do to the step response?
Q2
How do you identify and deal with mechanical resonance in a servo system?
Q3
Describe a servo tuning project you completed. What was the performance requirement and what was your methodology?
Q4
What is the difference between position control, velocity control, and force/torque control mode? When would you use each?
Q5
How does the motor-to-load inertia ratio affect your ability to tune a servo controller?
Tips and tricks
Lead every project with the performance target and whether you achieved it: "achieved 2nm RMS positioning error against 5nm spec"
Show the full loop: modelling → controller design → simulation → implementation → measurement
ASML specifically looks for candidates comfortable with high-bandwidth, high-accuracy motion — frame your experience in those terms
Experience with active vibration isolation or disturbance feedforward is a strong differentiator in the Brainport market
