I applied via Approached by Company and was interviewed in Sep 2024. There was 1 interview round.
The question is unclear and seems to be asking about the number of pH maintenance nickel crystals.
It is unclear what 'ph mainten nickel crystal' refers to
It is possible the interviewer made a mistake in phrasing the question
Ask for clarification or provide an educated guess based on context
pH maintenance raw materials dissolve in water and leaching time depend on the specific material and conditions.
The number of pH maintenance raw materials that dissolve in water varies depending on the specific materials being used.
Leaching time can also vary based on factors such as temperature, pH level, and agitation.
Examples of pH maintenance raw materials include limestone, dolomite, and hydrated lime.
The question is unclear and seems to be asking for the number of maintenance nickel GPL, which is not a standard term.
It is unclear what 'mainten nickel GPL' refers to
Ask for clarification or more context from the interviewer
Provide examples of similar terms or concepts you are familiar with
The question is unclear and seems to be asking for a percentage of maintenance nickel.
Ask for clarification on what 'mainten nickel %' refers to
Provide examples of different interpretations of the question
Offer to discuss the topic further to gain a better understanding
The question is unclear and lacks context. It seems to be asking about the percentage of nickel in a maintenance solid, but more information is needed for a precise answer.
Request clarification on the type of maintenance solid being referred to (e.g. metal alloy, coating, etc.)
Ask for the specific context in which the nickel percentage is relevant (e.g. for corrosion resistance, strength, etc.)

Solvent extraction is a method used to separate compounds based on their solubility in different solvents.
Solvent extraction involves mixing a sample with a solvent that can selectively dissolve the desired compound.
The mixture is then separated into layers, with the compound of interest being extracted into the solvent layer.
Common examples include extracting caffeine from coffee beans using water or extracting essent
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.
The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.
Common examples of distilla...
Evaporation is the process by which a liquid turns into a gas due to heat energy.
Evaporation occurs when molecules at the surface of a liquid gain enough energy to escape into the air.
It is a cooling process as it removes heat from the liquid.
Examples include water evaporating from a puddle on a hot day or sweat evaporating from our skin.
Evaporation is an important part of the water cycle.
Heat transfer is the process of energy moving from a warmer object to a cooler object.
Heat transfer can occur through conduction, convection, or radiation.
Conduction is the transfer of heat through direct contact between objects, like a metal spoon heating up in a hot drink.
Convection is the transfer of heat through the movement of fluids, like boiling water in a pot.
Radiation is the transfer of heat through electromag...
Solvent extraction involves using a solvent to separate compounds, while distillation involves separating compounds based on their boiling points.
Solvent extraction uses a solvent to dissolve the desired compound, which is then separated from the solvent. Distillation involves heating a mixture to separate compounds based on their boiling points.
Solvent extraction is often used in the extraction of essential oils from ...
Vaporization is the process of turning a liquid into a gas through heat, while evaporation is the process of a liquid turning into a gas at a temperature below its boiling point.
Vaporization requires heat to change a liquid into a gas, while evaporation can occur at room temperature.
Vaporization is a rapid process, such as boiling water to create steam, while evaporation is a slower process, like a puddle drying up.
Vap...

Chemical engineer company
A centrifugal pump works by converting mechanical energy from a motor into kinetic energy in a fluid through the rotation of an impeller.
Centrifugal pump uses an impeller to rotate and create a centrifugal force to move fluid.
The rotation of the impeller creates a low-pressure area at the center of the pump, drawing fluid in.
The fluid is then pushed outward by the centrifugal force, increasing its velocity and pressure...

Molecular weight is the sum of the atomic weights of all atoms in a molecule.
Molecular weight is calculated by adding up the atomic weights of all the atoms in a molecule.
It is expressed in atomic mass units (amu) or grams per mole (g/mol).
For example, the molecular weight of water (H2O) is 18.015 g/mol (2*1.008 + 15.999).
