10+ Sunshine Billiards Interview Questions and Answers
Q1. Do you know about the standard requirements of risk management for medical devices ?
Yes, the standard requirements of risk management for medical devices include ISO 14971 and FDA regulations.
ISO 14971 is an international standard for risk management of medical devices.
FDA regulations require medical device manufacturers to establish and maintain a risk management process.
Risk management for medical devices involves identifying hazards, estimating risks, and implementing controls to mitigate risks.
Examples of risk management activities include risk assessmen...read more
Q2. Difference between session and workflow in informatica
Session is a unit of work that extracts, transforms and loads data. Workflow is a collection of sessions that run in a specific order.
Session is a single task that performs ETL operations on data
Workflow is a collection of sessions that are executed in a specific order
Sessions can be reused in multiple workflows
Workflows can have multiple sessions
Sessions can have multiple tasks
Workflows can have multiple sessions with dependencies between them
Q3. What is Infusion Pump ?
An infusion pump is a medical device that delivers fluids, such as medications or nutrients, into a patient's body in controlled amounts.
Infusion pumps are commonly used in hospitals, clinics, and home healthcare settings.
They can deliver fluids intravenously, subcutaneously, or epidurally.
Infusion pumps help ensure accurate and precise delivery of medications, reducing the risk of human error.
Examples of infusion pumps include syringe pumps, volumetric pumps, and ambulatory ...read more
Q4. What is Bio-Metric & uses
Biometric refers to the measurement and analysis of unique physical or behavioral characteristics for identification or authentication purposes.
Biometric technology uses unique physical characteristics such as fingerprints, iris patterns, facial features, and voice patterns for identification.
It is commonly used for access control, time and attendance tracking, and security purposes.
Examples of biometric systems include fingerprint scanners at airports, facial recognition on ...read more
Q5. How to perform string reverse
To perform string reverse, we can use built-in functions or loop through the string and swap characters.
Use built-in functions like reverse() in Python or StringBuilder.reverse() in Java
Loop through the string and swap characters from both ends until the middle is reached
Convert the string to an array, reverse the array, and then convert it back to a string
Q6. *Laws of thermodynamics
The laws of thermodynamics describe the behavior of energy in a system.
The first law states that energy cannot be created or destroyed, only transferred or converted.
The second law states that the total entropy of a closed system will always increase over time.
The third law states that as temperature approaches absolute zero, the entropy of a system approaches a minimum.
These laws have important applications in fields such as physics, chemistry, and engineering.
For example, t...read more
Q7. Name and draw GD and T symbols
Answering the question about GD&T symbols
GD&T stands for Geometric Dimensioning and Tolerancing
Some common symbols include: concentricity, perpendicularity, flatness, circularity, position
Each symbol has a specific meaning and is used to communicate design requirements
GD&T is important in manufacturing and engineering to ensure parts are made to the correct specifications
Q8. Typecasting program in c
Typecasting in C involves converting one data type to another.
Typecasting can be done implicitly or explicitly.
Explicit typecasting involves using the cast operator.
Example: int x = 10; double y = (double) x;
Implicit typecasting is done automatically by the compiler.
Example: int x = 10; float y = x;
Typecasting can lead to loss of data or precision.
Q9. Explain oops concepts
OOPs concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.
Encapsulation - bundling of data and methods that operate on that data
Inheritance - ability of a class to inherit properties and characteristics from a parent class
Polymorphism - ability of objects to take on multiple forms or behaviors
Abstraction - hiding of complex implementation details and showing only the necessary information
Example: A car is an objec...read more
Q10. Explain about source qualifier
Source qualifier is a transformation in Informatica used to filter, join or modify data from source tables.
Source qualifier is used in mapping to extract data from source tables
It can be used to filter, join or modify data before passing it to target
It can be used to define the SQL query to extract data from source
It can be used to define the order in which data is extracted from source
