Torrent Pharmaceuticals Quality Engineer Interview Questions and Answers

I worked as a Quality Analyst at XYZ Company for 2 years.

• Conducted quality assurance testing on software applications

• Identified and reported bugs and issues to development team

• Collaborated with stakeholders to ensure product met quality standards

There are three types of validations: front-end, back-end, and database. Each type requires a different approach.

• Front-end validation is done on the client-side and checks for user input errors before submitting the form.

• Back-end validation is done on the server-side and checks for errors in the data submitted by the user.

• Database validation checks for data integrity and consistency in the database.

• Handling of validati...read more

Calibration of instruments is a crucial process to ensure accuracy and reliability of measurements.

• Calibration involves comparing the measurements of an instrument to a known standard.

• It helps in identifying and correcting any deviations or errors in the instrument's readings.

• Calibration ensures that the instrument is performing within acceptable limits and provides accurate results.

• It is necessary to calibrate instrum...read more

HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interaction with a stationary phase and mobile phase.

• HPLC stands for High-Performance Liquid Chromatography.

• The principle of HPLC involves the separation of components in a mixture based on their affinity for the stationary phase and mobile phase.

• The instrumentation of HPLC includes a pump to deliver the mobile phase, a ...read more

GC stands for Gas Chromatography, a principle and instrumentation used for separating and analyzing volatile compounds.

• GC is a technique used in analytical chemistry to separate and identify components of a mixture.

• It involves injecting a sample into a gas chromatograph, which vaporizes the sample and carries it through a column.

• The column contains a stationary phase that interacts with the sample components, causing t...read more

UV spectroscopy is a technique that uses ultraviolet light to analyze the chemical composition of substances.

• UV spectroscopy is based on the principle that molecules absorb ultraviolet light at specific wavelengths.

• The Beer-Lambert law relates the concentration of a substance to the amount of light it absorbs.

• UV spectroscopy is commonly used in pharmaceutical, environmental, and forensic analysis.

• It is used to determin...read more

pH stands for potential of hydrogen.

• pH is a measure of the acidity or alkalinity of a solution.

• It is a logarithmic scale ranging from 0 to 14.

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.

• pH is commonly used in various fields such as chemistry, biology, and environmental science.

The aufbau principle is a rule in quantum mechanics that states how electrons fill atomic orbitals.

• The principle states that electrons fill the lowest energy levels first before moving to higher energy levels.

• It follows the order of filling orbitals: 1s, 2s, 2p, 3s, 3p, 4s, etc.

• Each orbital can hold a maximum of two electrons with opposite spins.

• For example, the electron configuration of carbon (atomic number 6) is 1s²

Electron pairing occurs after half-filled orbitals in a subshell.

• Electron pairing is a phenomenon where two electrons occupy the same orbital.

• This occurs after each orbital in a subshell has been half-filled with electrons.

• The pairing of electrons is due to the principle of maximum multiplicity.

• For example, in the p subshell, electron pairing occurs after the first three orbitals have been half-filled with electrons.

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.

• Regular data audits and checks should be conducted to ensure data integrity.

• Examples of data integrity violations include data entry errors, system glitches, and unauthorized...read more
