A lathe machine is a tool used in machining to shape and cut materials by rotating the workpiece against a cutting tool.
A lathe machine consists of a bed, headstock, tailstock, and carriage.
The workpiece is mounted on the spindle and rotated at various speeds.
The cutting tool is held by the carriage and moves along the workpiece to shape it.
Lathe machines can perform various operations like turning, facing, drilling, a...
Cylinder division working involves dividing a cylinder into multiple parts.
Cylinder division is a process of cutting a cylinder into smaller sections.
It is commonly done using a lathe machine.
The lathe machine operator uses various tools and techniques to divide the cylinder.
The division can be done longitudinally or transversely depending on the requirements.
The operator needs to ensure precise measurements and accura...
L1 and L2 regression are regularization techniques used in machine learning to prevent overfitting by adding penalty terms to the loss function.
L1 regression adds the absolute values of the coefficients as penalty term (Lasso regression)
L2 regression adds the squared values of the coefficients as penalty term (Ridge regression)
L1 regularization can lead to sparse models with some coefficients being exactly zero
L2 regul...
AUC (Area Under the Curve) is a metric that measures the performance of a classification model. ROC (Receiver Operating Characteristic) is a graphical representation of the AUC.
AUC is a single scalar value that represents the area under the ROC curve.
ROC curve is a plot of the true positive rate against the false positive rate for different threshold values.
AUC ranges from 0 to 1, where a higher value indicates better ...
Parameter of random forest is the number of trees in the forest.
Number of trees in the forest affects model performance
Higher number of trees can lead to overfitting
Commonly tuned parameter in random forest algorithms
p, d, q values are parameters used in ARIMA time series models to determine the order of differencing and moving average components.
p represents the number of lag observations included in the model (autoregressive order)
d represents the degree of differencing needed to make the time series stationary
q represents the number of lagged forecast errors included in the model (moving average order)
For example, in an ARIMA(1,
AC stands for alternating current, a type of electrical current where the flow of electric charge periodically reverses direction.
AC is commonly used in homes and businesses for powering electrical devices.
AC is generated by power plants and distributed through power lines.
AC can be converted to DC (direct current) using devices like rectifiers.
Examples of AC-powered devices include refrigerators, air conditioners, and
QC focuses on testing the product to identify defects, while QE focuses on preventing defects through process improvements.
QC (Quality Control) involves testing the product to identify defects and ensure it meets quality standards.
QE (Quality Engineering) focuses on preventing defects by improving processes and implementing quality standards.
QC is reactive, while QE is proactive.
QC involves finding and fixing defects, ...
Sending keys using JSE in QA testing
Use the sendKeys() method to send keyboard input to a web element
Locate the element using findElement() method before sending keys
Example: driver.findElement(By.id("username")).sendKeys("example@gmail.com")
I applied via LinkedIn and was interviewed in Nov 2024. There was 1 interview round.
Tosca is a software testing tool that provides end-to-end test automation solutions.
Tosca is used for automated software testing.
It offers features like test case design, test data management, and test execution.
Tosca supports various technologies and platforms for testing.
It helps in accelerating the testing process and improving test coverage.
Example: Using Tosca to automate regression tests for a web application.
Tosca errors are common issues encountered while using the Tosca automation tool for testing.
Object not found error - occurs when Tosca cannot locate a specific object on the application under test.
Data binding error - happens when there is an issue with the data binding in Tosca.
Execution error - occurs during the execution of test cases in Tosca.
License error - happens when there is an issue with the Tosca license.

To test an application, I would follow a systematic approach to ensure all functionalities work as expected.
Create test cases based on requirements and user stories
Perform functional testing to check if all features work correctly
Conduct regression testing to ensure new changes do not affect existing functionalities
Test for performance, security, and usability
Use automation tools like Selenium for repetitive tests
To test an API, I would focus on functionality, performance, security, and integration.
Create test cases to cover all API endpoints and methods
Test input validation and error handling
Check response times and performance under different loads
Verify security measures such as authentication and authorization
Integrate API testing with automation tools like Postman or Selenium
Various tools are used in the project for testing purposes.
Selenium for automated testing
JIRA for bug tracking
Postman for API testing
