Pure Storage Mts Software Engineer Interview Questions and Answers for Experienced

Parity is calculated by counting the number of 1s in a binary sequence.

• Parity is used to detect errors in data transmission.

• Even parity means the number of 1s in the sequence should be even.

• Odd parity means the number of 1s in the sequence should be odd.

• Parity can be calculated using XOR operation on the binary sequence.

Baseline is the starting point of performance measurement while benchmark is the standard for comparison.

• Baseline is the initial measurement of performance used as a reference point for future comparisons.

• Benchmark is the standard or best practice used for comparison with the current performance.

• Baseline and benchmark are used to measure and improve performance.

• For example, a company may set a baseline for their websit...read more

I analyze logs, monitor system resources, and use profiling tools to identify and resolve performance issues.

• Analyze logs to identify potential bottlenecks

• Identify and eliminate unnecessary database queries

• Optimize network communication

• Implement caching mechanisms

• Conduct load testing to identify performa

iSCSI, SAN, FC, MAA are protocols used in storage networking.

• iSCSI (Internet Small Computer System Interface) is a protocol used to transmit SCSI commands over IP networks.

• SAN (Storage Area Network) is a network that provides block-level access to data storage.

• FC (Fibre Channel) is a high-speed network technology used to connect servers and storage devices.

• MAA (Massive Array of Idle Disks) is a storage architecture tha

Top command displays real-time system resource usage and process information.

• Top command shows system load, CPU usage, memory usage, and running processes.

• The first line shows overall system statistics.

• The second line shows CPU usage.

• The third line shows memory usage.

• The fourth line shows swap usage.

• The fifth line shows running processes.

• Press 'q' to exit top command.

Selenium 4 has new features like improved W3C support, relative locators, and better error handling.

• Improved W3C support for better browser compatibility

• Relative locators for easier element location

• Better error handling with detailed error messages

• New APIs for easier browser automation

• Support for Chromium-based Edge browser

• Integration with DevTools Protocol for better debugging

Encapsulation is the process of hiding implementation details and exposing only necessary information.

• Encapsulation is achieved through access modifiers like public, private, and protected.

• It helps in achieving data abstraction and information hiding.

• Encapsulation provides better control over the data and prevents unauthorized access.

• Example: A class with private variables and public methods to access them.

There are three types of waits in Selenium: Implicit Wait, Explicit Wait, and Fluent Wait.

• Implicit Wait: Waits for a certain amount of time before throwing an exception if the element is not found.

• Explicit Wait: Waits for a certain condition to occur before proceeding further in the code.

• Fluent Wait: Waits for a certain condition to occur with a defined frequency before proceeding further in the code.
