10+ Assistant Consultant and Developer Interview Questions and Answers

We used SonarQube and Checkstyle for static code analysis in the current project.

• SonarQube was used to analyze code quality and identify bugs, vulnerabilities, and code smells.

• Checkstyle was used to enforce coding standards and conventions.

• Both tools were integrated into our CI/CD pipeline for continuous analysis and improvement.

• We also used PMD for additional code analysis and to identify potential performance issues.

Docker provides advantages such as portability, scalability, and isolation.

• Docker allows for easy portability of applications across different environments.

• Docker enables efficient use of resources and scalability through containerization.

• Docker provides isolation between applications and their dependencies, reducing conflicts and improving security.

• Docker simplifies the deployment process and allows for faster iteration and updates.

• Docker can also improve collaboration betwe...read more

Filter phasing in Remedy refers to the order and conditions under which filters are executed in the workflow.

• Filters are executed in a specific order based on their phasing.

• Phasing determines how data is processed and can affect performance.

• Example: A filter with a higher phase number executes after one with a lower phase number.

• Filters can be set to run before or after specific actions, like field changes or submit actions.

Active link triggers an action when a specified condition is met, while filter restricts data based on specified criteria.

• Active link is used to trigger actions like sending notifications or updating records based on certain conditions

• Filter is used to restrict data displayed or processed based on specified criteria

• Active link is proactive in nature, while filter is reactive

• Example: An active link can be set up to send an email notification when a new ticket is created, while...read more

Remove duplicate characters from a string while preserving the original order of characters.

• Use a set to track seen characters and a list to build the result.

• Iterate through the string, adding characters to the result if they haven't been seen.

• Example: Input: 'hello', Output: 'helo'.

• Example: Input: 'programming', Output: 'progamin'.

Static call is resolved at compile time while dynamic call is resolved at runtime.

• Static call is determined by the type of the object at compile time.

• Dynamic call is determined by the type of the object at runtime.

• Static call is faster but less flexible compared to dynamic call.

• Example of static call: method overloading.

• Example of dynamic call: method overriding.

A Fibonacci number is a number in the Fibonacci sequence, where each number is the sum of the two preceding ones.

• Definition: The Fibonacci sequence starts with 0 and 1, and each subsequent number is the sum of the previous two.

• Formula: F(n) = F(n-1) + F(n-2) with base cases F(0) = 0 and F(1) = 1.

• Example: The first 10 Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34.

• Implementation: Fibonacci numbers can be calculated using recursion, iteration, or dynamic programming.

• Effi...read more

A marker interface is an empty interface used to indicate a specific property or behavior in Java without defining methods.

• Definition: A marker interface does not contain any methods or fields; it serves as a tagging mechanism.

• Example: The Serializable interface in Java is a marker interface that indicates an object can be serialized.

• Purpose: Marker interfaces are used to provide metadata about a class, allowing the Java runtime to perform specific actions.

• Usage: They are oft...read more

Checked exceptions are checked at compile-time while unchecked exceptions are not.

• Checked exceptions are declared in the method signature using the 'throws' keyword.

• Unchecked exceptions are not declared in the method signature.

• Examples of checked exceptions include IOException and SQLException.

• Examples of unchecked exceptions include NullPointerException and ArrayIndexOutOfBoundsException.

MVC life cycle is the sequence of events that occur during the processing of a web request in an MVC application.

• Request comes in through the browser

• Routing determines which controller and action to call

• Controller executes the action and returns a view

• View is rendered and sent back to the browser

Java 8 introduced several new features including lambda expressions, streams, and default methods.

• Lambda expressions allow for functional programming and simplify code.

• Streams provide a way to process collections of data in a functional way.

• Default methods allow for adding new methods to interfaces without breaking existing code.

• Other new features include the Optional class, Date and Time API, and Nashorn JavaScript engine.

COMP-3 fields are packed decimal fields used in COBOL programming to store numeric data efficiently.

• COMP-3 fields store numeric data in a packed format, using half the storage space of a regular decimal field.

• They are commonly used in COBOL programs for efficient storage and processing of numeric data.

• COMP-3 fields are encoded in a way that allows for easy arithmetic operations without the need for conversion.

• For example, a COMP-3 field with a value of 123 would be stored as ...read more
