Teva Pharmaceuticals Interview Questions, Process, and Tips

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

• The power of a pump is determined by the flow rate, head, and efficiency

• Flow rate is the volume of fluid passing through the pump per unit time

• Head is the height difference between the inlet and outlet of the pump

• Efficiency is the ratio of the actual power output to the power input

• The formula to calculate power is: Power = (...read more

Air flow in HVAC ducting can be calculated using the formula Q = AV

• Q = air flow rate in cubic feet per minute (CFM)

• A = cross-sectional area of the duct in square feet

• V = air velocity in feet per minute (FPM)

• Air velocity can be measured using a pitot tube or an anemometer

• Duct sizing and layout can affect air flow and should be considered in calculations

A reactor can be installed by following a few steps.

• Choose a suitable location for the reactor

• Prepare the foundation for the reactor

• Install the reactor vessel and associated equipment

• Connect the piping and electrical systems

• Test the reactor for proper functioning

Commissioning of a reactor involves a series of tests and procedures to ensure safe and efficient operation.

• Pre-commissioning checks and inspections

• Functional testing of equipment and systems

• Testing of safety systems

• Fuel loading and reactor startup

• Performance testing and optimization

• Final acceptance testing

• Documentation and training

• Regulatory approval

• Examples: Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR

Condensers are used to convert high-pressure vapor into liquid form.

• Condensers are used in various industries such as power plants, refrigeration systems, and chemical processing plants.

• They help in increasing the efficiency of the system by reducing the pressure and temperature of the vapor.

• They also help in recovering valuable materials from the vapor, such as water in a power plant.

• Examples of condensers include she...read more

Line clearance check points ensure safety and quality in the production process.

• Verify that all equipment and materials from the previous batch have been removed.

• Ensure that the production area is clean and free from any contamination.

• Confirm that all required documents and records are in place and properly filled out.

• Check that the equipment is properly calibrated and functioning correctly.

• Inspect that the correct raw...read more

Challenges faced while using a compression machine

• Ensuring proper calibration of the machine

• Maintaining consistent pressure and temperature

• Preventing contamination of the sample

• Ensuring proper cleaning and maintenance of the machine

• Dealing with unexpected errors or malfunctions

An audit trail is a record of all the events that occur during a process or transaction.

• It provides a chronological sequence of events.

• It helps in identifying errors, fraud, or unauthorized access.

• It ensures accountability and transparency.

• Examples include electronic medical records, financial transactions, and software development.

• It is important for compliance with regulations and standards.

AQL stands for Acceptable Quality Level and is a statistical sampling method used to determine the quality of a product or batch.

• AQL is used to determine the maximum number of defective items in a batch that is considered acceptable.

• It involves randomly selecting a sample of items from the batch and inspecting them for defects.

• The AQL level is determined based on the level of quality required for the product and the as...read more

Cpk is a statistical measure used to determine the capability of a process to produce products within customer specifications.

• Cpk measures the distance between the process mean and the closest specification limit.

• A Cpk value of 1 indicates that the process is capable of producing products within specifications.

• A Cpk value of less than 1 indicates that the process is not capable of producing products within specificatio...read more

Stratified sampling is a sampling technique where the population is divided into homogeneous groups and a sample is taken from each group.

• Stratified sampling is used to ensure that the sample represents the characteristics of the population.

• First, the population is divided into mutually exclusive and exhaustive groups called strata.

• Then, a random sample is taken from each stratum based on its proportion to the populati...read more

Carbon-carbon bonds can be prepared through various methods including coupling reactions and carbonylation reactions. Stereochemistry can be controlled through the choice of reagents and reaction conditions.

• Coupling reactions such as Suzuki-Miyaura coupling and Heck reaction can be used to form carbon-carbon bonds.

• Carbonylation reactions such as the Monsanto process can also be used to form carbon-carbon bonds.

• Stereoch...read more
