KPIT Technologies Senior CAE Engineer Interview Questions, Process, and Tips

To take design to an advanced level, one should focus on continuous learning, exploring new technologies, collaborating with others, and seeking feedback.

• Continuously learn and stay updated with the latest design trends and technologies.

• Explore new tools and software that can enhance the design process and improve efficiency.

• Collaborate with other designers, engineers, and stakeholders to gain different perspectives an...read more

Program to fetch second highest number from array

• Sort the array in descending order

• Return the second element of the sorted array

Delete removes specific rows while truncate removes all rows from a table.

• Delete is a DML command while truncate is a DDL command.

• Delete is slower than truncate as it logs each row deletion while truncate does not.

• Delete can be rolled back while truncate cannot be rolled back.

• Delete can be used with a WHERE clause to remove specific rows while truncate removes all rows.

• Delete does not reset the identity of a table whil

OOPS pillars are the fundamental principles of Object-Oriented Programming.

• Encapsulation - bundling of data and methods that operate on that data

• Inheritance - ability of a class to inherit properties and characteristics from its parent class

• Polymorphism - ability of objects to take on multiple forms or have multiple behaviors

• Abstraction - hiding of complex implementation details and showing only the necessary informati

Abstract and interface are both used for abstraction in object-oriented programming.

• Abstract classes can have both abstract and non-abstract methods, while interfaces can only have abstract methods.

• Classes can implement multiple interfaces, but can only inherit from one abstract class.

• Abstract classes can have constructors, while interfaces cannot.

• Interfaces are used for defining contracts, while abstract classes are u

MVC filters are used to intercept and modify HTTP requests and responses in ASP.NET MVC applications.

• Filters can be used for authentication, caching, logging, and exception handling.

• Filters can be applied globally or to specific controllers or actions.

• The execution sequence of filters is determined by their type and scope.

• The order of execution can be modified using the Order property.

• Some common filter types include A...read more

Exception handling in MVC is crucial for error-free application development.

• MVC framework provides a built-in exception handling mechanism.

• Custom exception handling can be implemented using try-catch blocks.

• Global exception handling can be set up in the Global.asax file.

• Logging exceptions can help in debugging and improving application performance.

SOLID design principles are a set of guidelines for writing maintainable and scalable code.

• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open/Closed Principle: A class should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Subtypes should be substitutable for their base types.

• I - Interface Segregation Principle: Clients should not be forced t...read more

Sort map entries based on values

• Use a TreeMap to sort the entries based on values

• Implement a Comparator to compare the values

• Convert the sorted entries to a LinkedHashMap to maintain the order

Object class is inherited by each subclass separately in multiple levels of inheritance.

• Each subclass inherits the object class of its parent class.

• If a subclass has multiple parent classes, it inherits the object class of each parent class separately.

• Object class is the root class of all classes in Java and provides basic methods and properties.

• Example: Class C extends Class B, which extends Class A. Each class inheri...read more

Array list and hashmap are data structures used for storing and accessing data in memory.

• Array list is a dynamic array that can grow or shrink in size as needed.

• Hashmap is a key-value pair data structure that allows for fast retrieval of values based on their keys.

• Array list is implemented using an array, while hashmap is implemented using a hash table.

• Array list is useful when the data needs to be accessed sequentiall...read more

A runnable is a functional interface that represents a task to be executed, while a thread is a separate path of execution.

• A runnable can be executed by a thread or an executor service

• A thread is a lightweight process that can run concurrently with other threads

• Threads can be used for parallelism, concurrency, and asynchronous programming

• Example: Runnable r = () -> System.out.println("Hello World"); Thread t = new Thre

Abstract classes are used when we want to provide a default implementation, while interfaces are used when we want to enforce a contract.

• Use abstract classes when you want to provide a default implementation for some methods.

• Use interfaces when you want to enforce a contract that must be implemented by the implementing class.

• Abstract classes can have constructors, while interfaces cannot.

• A class can implement multiple ...read more

Find the first non-repeating character in a string.

• Iterate through the string and count the frequency of each character.

• Iterate through the string again and return the first character with frequency 1.

• Use a hash table to store the frequency of each character.
