Express Scripts Interview Questions and Answers

Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid to transmit power.

• Pneumatic systems use air as the working fluid, while hydraulic systems use liquid.

• Pneumatic systems are typically used for lighter loads and faster movements, while hydraulic systems are used for heavier loads and slower movements.

• Pneumatic systems are generally less expensive and easier to maintain compared to ...read more

There are several types of welding techniques used in various industries.

• Arc welding: Uses an electric arc to create heat and join metals.

• MIG welding: Uses a consumable wire electrode and shielding gas to join metals.

• TIG welding: Uses a non-consumable tungsten electrode and inert gas to join metals.

• Spot welding: Joins metal sheets by applying pressure and heat at specific points.

• Flux-cored arc welding: Similar to MIG w...read more

CNC and lathe machines are used for precision cutting and shaping of materials.

• CNC machines use computer programming to control the cutting tools, allowing for highly precise and complex shapes to be created.

• Lathe machines are used for turning and shaping cylindrical objects, such as metal rods or wooden dowels.

• Both machines are commonly used in manufacturing and engineering industries.

• Examples of products made using C...read more

Data integrity is crucial for accurate decision-making and maintaining trust in the organization.

• Data integrity ensures that data is accurate, complete, and consistent.

• It is important to have proper data management policies and procedures in place.

The reagent addition rate for exothermic reaction can be found by monitoring the temperature and adjusting the rate accordingly.

• Start with a small addition rate and gradually increase it while monitoring the temperature.

• Use a thermometer or temperature sensor to measure the temperature.

• Adjust the rate based on the temperature changes to maintain a steady reaction rate.

• Consider the reaction kinetics and the heat transfe...read more

A PID temperature indicator controls temperature by adjusting heating/cooling based on feedback from sensors.

• PID stands for Proportional-Integral-Derivative, which are the three control modes used to adjust temperature.

• The indicator receives input from temperature sensors and compares it to the desired temperature setpoint.

• Based on the difference between the two, the PID controller adjusts the heating/cooling output to...read more

MTSR, DSC, and TSC are metrics used in call centers to measure performance and efficiency.

• MTSR stands for Mean Time to Service Request and measures the average time it takes for a customer's service request to be resolved.

• DSC stands for Delayed Service Calls and measures the number of service calls that were not resolved within a certain timeframe.

• TSC stands for Total Service Calls and measures the total number of serv...read more

XRD is a technique used to determine the crystal structure of a material. Crystalline and amorphous materials show different patterns.

• XRD stands for X-ray diffraction

• Crystalline materials have a regular, repeating pattern of atoms while amorphous materials lack this pattern

• XRD patterns of crystalline materials show sharp peaks while amorphous materials show broad peaks

• XRD can be used to identify unknown crystalline mat...read more

The degree of freedom of water at triple point is 0.

• Triple point is the temperature and pressure at which solid, liquid, and gas phases of a substance coexist in thermodynamic equilibrium.

• At triple point, the degree of freedom of a substance is zero because all three phases coexist in equilibrium.

• Water has a triple point at 273.16 K (0.01 °C) and a pressure of 611.73 Pa.

• At triple point, water can exist as ice, liquid w

Risk is the possibility of loss or harm occurring due to uncertain events or circumstances.

• Risk involves uncertainty and the potential for negative consequences.

• It can be managed through risk assessment, mitigation, and transfer.

• Examples of risks include financial risks, health risks, and environmental risks.

• Risk can also present opportunities for growth and innovation.

The power required for a pump can be calculated using the formula: Power = (Flow rate x Head) / Efficiency

• Calculate the flow rate of the pump

• Determine the head or pressure required

• Consider the efficiency of the pump

• Use the formula: Power = (Flow rate x Head) / Efficiency

• Example: If the flow rate is 1000 liters per minute, the head is 50 meters, and the efficiency is 80%, the power required would be (1000 x 50) / 0.8 =
