I applied via Approached by Company and was interviewed before Mar 2023. There was 1 interview round.
Black Box Testing is a software testing method where the internal structure/design of the application is not known to the tester.
Tester focuses on the functionality of the software without knowing its internal code
Tests are based on requirements and specifications
Input data is provided and output is verified without knowing how the software processes the data
Integration testing is a type of testing where individual units are combined and tested as a group to ensure they work together correctly.
Integration testing focuses on testing the interactions between different components/modules of a system.
It helps in identifying issues related to communication between different units.
Examples include testing the integration of a login module with a database or testing the integrati...
Beta testing is the final phase of testing before a software product is released to the public, where real users test the product in a real-world environment.
Beta testing helps identify bugs, usability issues, and gather feedback from real users.
Beta testers are usually external users who volunteer to test the product before its official release.
Beta testing can be open to the public or limited to a select group of tes...
SDLC is the process of developing software, while STLC is the process of testing software.
SDLC focuses on the development of software from planning to deployment.
STLC focuses on the testing activities like test planning, test design, test execution, and test closure.
SDLC includes phases like requirements gathering, design, coding, testing, and deployment.
STLC includes phases like test planning, test design, test execut...

I applied via Recruitment Consulltant and was interviewed before Oct 2022. There were 3 interview rounds.
A relay holding circuit diagram is used to keep the relay in the energized state even after the control signal is removed.
The circuit typically includes a holding contact that maintains the relay coil energized.
A latching relay can also be used for holding without continuous power supply.
Examples: ladder logic diagram with a holding contact, latching relay circuit diagram.
PNP and NPN are types of bipolar junction transistors commonly used in electronic circuits.
PNP transistor has a layer of N-type semiconductor between two layers of P-type semiconductor, while NPN transistor has a layer of P-type semiconductor between two layers of N-type semiconductor.
In a PNP transistor, current flows from the emitter to the base and then to the collector, while in an NPN transistor, current flows fro...
There are various types of sensors used for different purposes.
Temperature sensors (e.g. thermocouples, thermistors)
Pressure sensors (e.g. piezoelectric sensors)
Motion sensors (e.g. accelerometers, gyroscopes)
Proximity sensors (e.g. ultrasonic sensors)
Light sensors (e.g. photodiodes, phototransistors)
PLC stands for Programmable Logic Controller, which is a digital computer used for automation of electromechanical processes.
PLC is used to control machinery in manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability control.
It is programmed using a specialized computer language, typically ladder logic or function block diagram.
PLCs are commonly used in industrie...

TTR stands for Total Thickness Range and is required for powder coating process to ensure proper adhesion and durability.
TTR is the range of thickness of the substrate and any coatings applied to it
It is important for powder coating as it ensures proper adhesion and durability
If the TTR is too large, the coating may not adhere properly or may crack and peel over time
Examples of substrates with varying TTR include alumi
Detection and prevention poka-yoke refers to the use of techniques to identify and prevent errors in a process.
Poka-yoke is a Japanese term for mistake-proofing
Detection poka-yoke involves identifying errors as they occur
Prevention poka-yoke involves designing processes to prevent errors from occurring
Examples of poka-yoke include using checklists, color-coding, and physical barriers
Poka-yoke can improve quality, reduc
Decrease in pH can occur due to various factors in conversion coating.
Decrease in pH can be caused by the addition of an acid or acidic solution.
Presence of reactive metals in the coating can lead to a decrease in pH.
Contamination by organic materials or impurities can also lower the pH.
Chemical reactions during the conversion coating process may result in pH decrease.
Examples of conversion coatings include phosphating
To prepare 0.1 N H2SO4 & NaOH, calculate the required amount of solute and dissolve it in distilled water.
Calculate the molar mass of H2SO4 and NaOH
Determine the required amount of solute using the formula: N = (W/M) x (1000/V)
Dissolve the calculated amount of solute in distilled water to make 1 liter of solution
Standardize the solution using a primary standard
Use a burette to measure the volume of solution needed for
To cross verify 0.1 normality H2SO4, use a standard solution of NaOH and an indicator.
Prepare a standard solution of NaOH of known concentration.
Add a few drops of an indicator such as phenolphthalein to the H2SO4 solution.
Titrate the H2SO4 solution with the NaOH solution until the endpoint is reached.
The endpoint is when the indicator changes color, indicating that all the H2SO4 has reacted with the NaOH.
Calculate the...
Prepare a pH buffer solution as per defined standard in tablet.
Determine the required pH value and buffer capacity
Select the appropriate buffer system and calculate the required amounts of buffer components
Dissolve the buffer components in water and adjust the pH as necessary
Check the pH and adjust if necessary
Filter the solution and store in a clean container
Use a calibrated pH meter to verify the pH of the solution
