FIS Interview Questions and Answers
202 Interview questions
Static method calls are resolved at compile time, while dynamic method calls are resolved at runtime based on the object's type.
Static method calls are bound to the class, not the instance. Example: ClassName.methodName().
Dynamic method calls are bound to the object instance, allowing for polymorphism. Example: object.methodName().
Static methods cannot be overridden, while dynamic methods can be overridden in subc...
The first round focused on technical definitions in programming and testing methodologies.
Questions included definitions of OOP concepts like inheritance and polymorphism.
Technical terms such as 'unit testing' and 'integration testing' were discussed.
Examples of programming languages like Python and Java were used to illustrate concepts.

Reversing a string in Java can be done using various methods, including StringBuilder, recursion, or character arrays.
Using StringBuilder: Create a StringBuilder object, append the string, and use the reverse() method. Example: StringBuilder sb = new StringBuilder("hello"); sb.reverse(); // Output: "olleh"
Using a for loop: Convert the string to a character array, then iterate backwards to build the reversed string...
Selenium scripts can handle dynamic web elements using waits and locators to ensure elements are interactable.
Use Explicit Waits: `WebDriverWait` allows waiting for specific conditions. Example: `WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOf(element));`
Utilize XPath: Dynamic elements often change IDs. Use XPath with contains() or starts-with(). Example: `driver.findElement(By.xpath("//div[contain...
The Singleton pattern ensures a class has only one instance and provides a global point of access to it.
1. A Singleton class has a private constructor to prevent instantiation from outside.
2. It holds a static reference to its own instance.
3. It provides a public static method to access the instance.
4. Thread safety can be achieved using locking mechanisms or lazy initialization.
Abstract classes can have implementations; interfaces cannot. Both define contracts for derived classes.
Abstract classes can contain both abstract methods (without implementation) and concrete methods (with implementation).
Interfaces can only contain method signatures (abstract methods) and properties, with no implementation.
A class can inherit from only one abstract class (single inheritance), but it can implemen...

Integration of new ...
The .NET Framework is Windows-only, while .NET Core is cross-platform and modular, designed for modern app development.
.NET Framework is primarily for Windows applications, whereas .NET Core supports Windows, macOS, and Linux.

Self-attention is a mechanism that allows models to weigh the importance of different words in a sequence when processing them.
Self-attention computes a weighted representation of input sequences, focusing on relevant parts.
It uses three vectors: Query, Key, and Value to determine the importance of each word.
For example, in the sentence 'The cat sat on the mat', 'cat' might pay more attention to 'sat' than 'the'.
S...
Logistic regression predicts binary outcomes, while linear regression predicts continuous values.
Linear regression outputs continuous values (e.g., predicting house prices).
Logistic regression outputs probabilities for binary outcomes (e.g., disease presence: yes/no).
Linear regression uses a straight line to model relationships; logistic regression uses an S-shaped curve (logistic function).
In linear regression, t...
