Accenture Software Developer Interview Questions and Answers
124 Interview questions
SOLID principles are five design principles aimed at making software designs more understandable, flexible, and maintainable.
S - Single Responsibility Principle: A class should have one reason to change. Example: A class handling user data should not also handle logging.
O - Open/Closed Principle: Software entities should be open for extension but closed for modification. Example: Use interfaces to add new features...
The if __name__ == '__main__' construct allows code to run only when a script is executed directly, not when imported.
It checks if the script is being run directly or imported as a module.
Code inside this block runs only when the script is executed directly.
Example: if __name__ == '__main__': print('Hello, World!')
Useful for testing code without executing it when imported.
Helps in organizing code and separating mo...
HTML is the standard markup language for creating web pages, structuring content, and defining elements on the internet.
HTML stands for Hypertext Markup Language.
It uses tags to define elements, e.g., <p> for paragraphs, <h1> for headings.
HTML documents are structured in a tree-like format, with nested elements.
It can include multimedia elements like images (<img>) and videos (<video>).
HTML...
Find the contiguous subarray with the largest sum in an integer array using an efficient algorithm.
Kadane's Algorithm: This algorithm efficiently finds the maximum sum subarray in O(n) time by maintaining a running sum.
Initialization: Start with two variables, maxSum and currentSum, initialized to the first element of the array.
Iterate through the array: For each element, update currentSum to be the maximum of the...

To find the minimum element in an array, iterate through the elements and track the smallest value encountered.
Initialize a variable to hold the minimum value, e.g., minElement = arr[0].
Loop through the array starting from the first element.
Compare each element with minElement; if it's smaller, update minElement.
Return minElement after completing the loop.
Example: For array [3, 1, 4, 1, 5], the minimum is 1.
The maximum common subsequence (MCS) is the longest sequence that appears in the same order in both strings.
Dynamic Programming Approach: Use a 2D array to store lengths of common subsequences.
Example: For strings 'ABCBDAB' and 'BDCAB', MCS is 'BCAB'.
Recursive Approach: Define a function that compares characters and explores both possibilities.
Time Complexity: O(m*n), where m and n are lengths of the two strings.
Java 8 introduced significant features like lambda expressions, streams, and the new Date-Time API, enhancing code efficiency and readability.
Lambda Expressions: Enable concise representation of functional interfaces. Example: (x, y) -> x + y.
Streams API: Facilitates functional-style operations on collections. Example: list.stream().filter(x -> x > 10).collect(Collectors.toList()).
Optional Class: Helps av...
Spring Boot profiles allow developers to define different configurations for different environments.
Profiles can be activated via command line: `--spring.profiles.active=dev`.
You can define properties in `application-dev.properties` for the 'dev' profile.
Profiles can be used to separate configurations for development, testing, and production.
Use `@Profile` annotation to conditionally load beans based on the active...
A concurrent hash map is a thread-safe data structure that allows concurrent access and modification by multiple threads.
Supports high concurrency with minimal locking, improving performance in multi-threaded environments.
Uses a segmented locking mechanism, allowing multiple threads to access different segments simultaneously.
Example in Java: `ConcurrentHashMap<String, Integer> map = new ConcurrentHashMap<...
Streams API's map() transforms elements, while flatMap() flattens nested structures into a single stream.
map() applies a function to each element, returning a new stream. Example: list.stream().map(String::toUpperCase).
flatMap() is used when each element can produce multiple elements, flattening the result. Example: list.stream().flatMap(List::stream).
map() retains the structure of the original stream, while flatM...

(5 Questions)
- Q1. What is a polymorphism?
- Q2. Can you explain difference between == and euqals()?
- Ans.
The == operator checks for equality of values, while the equals() method checks for equality of objects.
The == operator compares the values of two objects, while the equals() method compares the objects themselves.
The == operator is used for primitive data types, while the equals() method is used for objects.
Example: int a = 5; int b = 5; a == b will return true, but a.equals(b) will not work as int is a primitive data...
- Q3. What is dependency inversion?
- Ans.
Dependency inversion is a design principle where high-level modules should not depend on low-level modules, but both should depend on abstractions.
High-level modules should not depend on low-level modules, both should depend on abstractions
Abstractions should not depend on details, details should depend on abstractions
Inversion of control containers like Spring Framework in Java implement dependency inversion
- Q4. Can you explain ACID?
- Ans.
ACID is a set of properties that guarantee database transactions are processed reliably.
ACID stands for Atomicity, Consistency, Isolation, Durability
Atomicity ensures that all operations in a transaction are completed successfully or none at all
Consistency ensures that the database remains in a valid state before and after the transaction
Isolation ensures that multiple transactions can occur concurrently without affect...
- Q5. Please tell me about isolation levels
- Ans.
Isolation levels in databases determine how transactions interact with each other.
Isolation levels define the degree to which one transaction must be isolated from the effects of other transactions.
Common isolation levels include READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE.
Higher isolation levels provide more data consistency but may impact performance.
For example, in READ COMMITTED isolation le...

- Q1. Explain HashMap's internal working.
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.
HashMap uses an array of buckets to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index (collision), a linked list or tree is used to store multiple entries at that index.
To retrieve a value, the ke...
