These are five sample questions from Bryq’s Assembly Technician assessment, a job-specific test for hiring assembly technicians, production assemblers and electromechanical technicians. The full assessment covers five skills: assembly knowledge, hand tools, following instructions, wiring schematics and diagnostic testing. Questions combine technical assembly knowledge with realistic production-line scenarios, each with four options to choose from.
Assembly Technician Knowledge
Question
What is the main reason for using an interference (press) fit between a bearing and a shaft?
Select your answer
To prevent the bearing ring from rotating on the shaft under load.
To reduce the amount of lubrication the bearing needs.
To compensate for misalignment between the shaft and housing.
To allow the bearing to be removed easily for maintenance.
WHY IS THIS THE CORECT ANSWER
In an interference fit, the bearing’s inner ring is slightly smaller than the shaft, so it grips firmly and can’t creep or spin under load. This prevents fretting wear and shaft damage, but it also means the bearing must be pressed on and off with the proper tools.
Hand Tools
Question
You need to tighten a series of fasteners to 25 Nm using a click-type torque wrench. Which practice gives the most accurate result?
Select your answer
Pull smoothly at the handle grip and stop as soon as it clicks.
Keep pulling slightly after the click to make sure it’s tight.
Apply a quick jerk to the handle until the wrench clicks.
Hold the wrench near its head for better control.
WHY IS THIS THE CORECT ANSWER
A click-type wrench is calibrated for a steady pull at the handle grip and releases at the set torque. Jerking it, pulling past the click or holding it elsewhere along its length all change the torque actually applied, usually over-tightening the fastener.
Following Instructions
Question
The work instruction for a subassembly specifies a torque of 12 Nm, but the drawing posted at your station shows 21 Nm for the same fastener. What should you do?
Select your answer
Pause that step and confirm the correct value with engineering before continuing.
Use the lower value to protect the part, and tell your supervisor about the conflict.
Use the work instruction’s value, since it’s usually the more recent document.
Use whichever value the other technicians on the line normally apply.
WHY IS THIS THE CORECT ANSWER
When two controlled documents disagree, at least one is wrong, and either value could cause a failure. Under-torqued fasteners can work loose, while over-torqued ones can strip or crack parts. Confirming the value with engineering before continuing protects the product and gets the documents corrected.
Wiring Schematics
Question
On a control schematic, a relay’s contacts are drawn open. What does this mean?
Select your answer
The contacts are normally open, shown with the coil de-energized.
The relay is faulty and needs replacing.
The contacts stay open while the circuit is running.
The relay has been disconnected from the circuit.
WHY IS THIS THE CORECT ANSWER
Schematics show switching devices in their resting state, with relay coils de-energized. Contacts drawn open are normally open (NO) and close when the coil is energized, which is key to reading how a control circuit behaves.
Diagnostic Testing
Question
A newly assembled board passes a continuity test across a connector, but the circuit fails functional testing. A voltage drop test under load shows 1.8 V across the same connection. What is the most likely cause?
Select your answer
A high-resistance joint, such as a cold or cracked solder joint.
An open circuit caused by a missing wire.
A supply voltage set above specification.
A short circuit to ground at the connector.
