I applied via Referral and was interviewed before Jul 2022. There were 3 interview rounds.
The percentage of buffer used in mobile phase and the use of SLS in disso and its allowed percentage.
The percentage of buffer used in the mobile phase depends on the specific experiment and the desired separation of compounds.
Buffer is used in the mobile phase to maintain the pH and ionic strength, which can affect the separation and stability of analytes.
The percentage of buffer can range from 5% to 50% or more, depen...
The sink condition is decided based on various factors such as the purpose of the sink, the type of research being conducted, and the desired outcome.
Consider the purpose of the sink - Is it for disposal, storage, or analysis of substances?
Evaluate the type of research being conducted - Does it involve chemical reactions, biological samples, or physical measurements?
Assess the desired outcome - Are you looking for pres...
The criteria/limit for impurity recovery depends on the specific research study and the desired purity level.
The criteria for impurity recovery may include the maximum allowable impurity concentration or percentage.
The limit for impurity recovery can be determined based on regulatory guidelines or industry standards.
The desired purity level may vary depending on the application or intended use of the research findings.

Mass balance is a principle used in various scientific disciplines to account for the mass of substances in a system.
Mass balance is based on the principle of conservation of mass, which states that mass cannot be created or destroyed, only transferred or transformed.
It involves tracking the inputs, outputs, and accumulation of mass within a system.
Mass balance equations are commonly used in environmental science, chem...
RF values are important in chromatography to identify and separate compounds.
RF value is the ratio of the distance traveled by a compound to the distance traveled by the solvent front in chromatography.
It helps in identifying and separating compounds based on their polarity and solubility.
RF values can be used to compare compounds and determine their purity.
For example, in thin-layer chromatography, RF values are used ...

I applied via Company Website and was interviewed before Sep 2020. There were 3 interview rounds.
The role of a ligand in Suzuki coupling reaction is to facilitate the formation of a stable complex between the catalyst and the reactants.
A ligand coordinates with the catalyst metal center, enhancing its reactivity and selectivity.
It helps in stabilizing the transition state and lowering the activation energy of the reaction.
Different ligands can influence the reaction rate and product distribution.
Common ligands use...
I am well-versed with the mechanism of the Grignard reaction.
Grignard reaction involves the addition of an organomagnesium halide to a carbonyl compound.
It is a nucleophilic addition reaction.
The reaction is highly useful in organic synthesis, especially for the formation of carbon-carbon bonds.
Examples include the synthesis of alcohols, carboxylic acids, and ketones.
The reaction is named after French chemist Victor Gr

I applied via Naukri.com and was interviewed before Jan 2022. There was 1 interview round.
The Grignard Reaction is a nucleophilic addition reaction between an organomagnesium halide and a carbonyl group.
Named after French chemist Victor Grignard
Used to form carbon-carbon bonds
Commonly used in organic synthesis
Example: Grignard reagent (RMgX) + aldehyde (R'CHO) -> alcohol (R'CH(OH)R)

I was interviewed in Sep 2016.
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 ...
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...
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...
