B M Construction Co Senior Engineer Mechanical Interview Questions, Process, and Tips

I have handled a wide range of machinery including CNC machines, 3D printers, industrial robots, and hydraulic systems.

• CNC machines

• 3D printers

• Industrial robots

• Hydraulic systems

Hydraulic systems use fluid to transmit power and are commonly used in various mechanical applications.

• Hydraulic systems use a fluid (usually oil) to transmit power.

• They consist of a hydraulic pump, valves, cylinders, and hydraulic fluid.

• Schematic diagrams show the flow of hydraulic fluid and components in the system.

• Examples of hydraulic systems include hydraulic brakes in cars and hydraulic lifts in construction equi

Hydraulic systems use liquid to transmit power while pneumatic systems use gas.

• Hydraulic systems use incompressible fluid (usually oil) while pneumatic systems use compressible gas (usually air)

• Hydraulic systems can handle higher loads and pressures compared to pneumatic systems

• Pneumatic systems are generally faster in operation compared to hydraulic systems

• Hydraulic systems are more suitable for heavy-duty application...read more

I handle breakdowns by staying calm, assessing the situation, troubleshooting the issue, and implementing a solution.

• Stay calm and composed to think clearly

• Assess the situation to understand the root cause

• Troubleshoot the issue systematically

• Implement a solution efficiently

• Document the breakdown and solution for future reference

I manage vendors and subcontractors by establishing clear communication channels, setting expectations, monitoring progress, and resolving any issues promptly.

• Establish clear communication channels with vendors and subcontractors

• Set expectations regarding deliverables, timelines, and quality standards

• Monitor progress regularly to ensure project milestones are being met

• Resolve any issues or conflicts promptly to prevent...read more

Maintenance schedule is a planned timetable for performing routine maintenance tasks on equipment or machinery.

• Maintenance schedule outlines when specific maintenance tasks need to be performed

• It helps in preventing breakdowns and ensuring optimal performance of equipment

• Examples include regular oil changes for vehicles, annual HVAC system inspections, and monthly filter replacements

Engine oil, gear oil, axle oil, and hydraulic oil serve different purposes in a vehicle and have specific grades for optimal performance.

• Engine oil is used to lubricate internal combustion engines and comes in different grades such as 5W-30 or 10W-40.

• Gear oil is designed for transmissions, differentials, and transfer cases to reduce friction and wear. Common grades include 75W-90 or 80W-90.

• Axle oil is specifically form...read more

Major components of a batching plant include aggregate bins, conveyor belts, mixers, cement silos, control panels, and water tanks.

• Aggregate bins for storing different types of aggregates

• Conveyor belts for transporting materials to the mixer

• Mixers for mixing the aggregates with cement and water

• Cement silos for storing cement

• Control panels for controlling the batching process

• Water tanks for storing water used in the mix
