Accenture Team Lead Interview Questions, Process, and Tips

Approval flows are defined by mapping out the steps and decision points in a process to determine who needs to approve at each stage.

• Identify all stakeholders involved in the approval process

• Map out the steps and decision points in the process

• Determine the criteria for approval at each stage

• Assign specific approvers to each step based on criteria

• Implement a system or tool to automate and track approval flows

Four pillars of OOPs are Abstraction, Encapsulation, Inheritance, and Polymorphism.

• Abstraction: Hiding implementation details and showing only necessary information.

• Encapsulation: Binding data and functions together and restricting access to them.

• Inheritance: Acquiring properties and behavior of a parent class by a child class.

• Polymorphism: Ability of an object to take many forms and perform different actions based on

Primary key uniquely identifies a record in a table, while unique key ensures uniqueness of a column.

• Primary key cannot have null values, while unique key can have one null value.

• A table can have only one primary key, but multiple unique keys.

• Primary key is used as a foreign key in other tables, while unique key is not.

• Example: Employee ID can be a primary key, while email address can be a unique key.

Existing project follows microservices architecture.

• The project is divided into smaller, independent services.

• Each service has its own database and communicates with other services through APIs.

• This architecture allows for easier scalability and maintenance.

• Examples of microservices in the project may include user authentication, payment processing, and inventory management.

Compile time polymorphism is achieved through function overloading and templates, while run time polymorphism is achieved through virtual functions.

• Compile time polymorphism is resolved at compile time, while run time polymorphism is resolved at run time.

• Function overloading allows multiple functions with the same name but different parameters to be defined.

• Templates allow functions or classes to be defined with generi...read more

No, static methods cannot be overridden.

• Static methods belong to the class and not to the instance of the class.

• They can be called using the class name without creating an object.

• Subclasses can have methods with the same name as the static method in the parent class, but it won't override it.

Yes, instance variables can be overridden.

• Instance variables can be overridden in subclasses.

• The subclass can declare a variable with the same name as the superclass variable.

• The subclass variable will then override the superclass variable.

• This is known as variable shadowing.

• Example: class A has an instance variable 'x', class B extends A and also has an instance variable 'x', B's 'x' will override A's 'x'.

Collection algorithms are used to organize and manage data in data structures.

• Some common collection algorithms include sorting, searching, and hashing.

• Sorting algorithms include bubble sort, quicksort, and merge sort.

• Searching algorithms include linear search and binary search.

• Hashing algorithms include MD5 and SHA-1.

• The choice of algorithm depends on the type of data and the desired outcome.

Hibernate get and load method difference

• get() method returns null if the object is not found in the database

• load() method throws ObjectNotFoundException if the object is not found in the database

• get() method hits the database immediately

• load() method returns a proxy object and hits the database only when the actual data is needed

Hibernate patch is a fix for bugs or issues in the Hibernate framework.

• Hibernate patch is a software update that addresses bugs or issues in the Hibernate framework.

• It is used to fix problems related to database connectivity, performance, and security.

• Hibernate patches are released periodically and can be downloaded from the official website.

• For example, Hibernate 5.4.30.Final is a patch release that fixes several issu

Hibernate supports different criteria methods for querying data from the database.

• Criteria API: used to create and execute object-oriented queries

• Example: Criteria criteria = session.createCriteria(Employee.class);

• DetachedCriteria: used to create criteria queries outside of a session

• Example: DetachedCriteria criteria = DetachedCriteria.forClass(Employee.class);

• Query by Example: used to query based on an example object

• E...read more

Java 8 intermediate and terminal operations have the same speed.

• Intermediate operations are lazy and do not execute until a terminal operation is called

• Terminal operations trigger the execution of the entire stream pipeline

• The speed of intermediate and terminal operations depends on the size of the stream and the complexity of the operations

• Therefore, it is not accurate to say that one is always faster than the other

Transactional propagations refer to the way transactions are managed and propagated across multiple resources.

• Propagation behavior determines how transactions are managed across multiple resources

• There are different types of propagation behavior such as REQUIRED, REQUIRES_NEW, SUPPORTS, MANDATORY, NOT_SUPPORTED, NEVER

• REQUIRED - transaction must be present, REQUIRES_NEW - new transaction is created, SUPPORTS - transacti...read more

A predicate is a statement that evaluates to true or false, while a function returns a value.

• A predicate is used to test a condition and returns a boolean value.

• A function takes input parameters and returns a value based on those parameters.

• Predicates are commonly used in conditional statements and loops.

• Functions can be used for a variety of purposes, such as calculations or data manipulation.

• Example of a predicate: x
