What are the most common coding exercises for Enterprise Software interviews?

Possessing a strong understanding of data structures and algorithms is essential for software developers, particularly when dealing with enterprise software. By reviewing and mastering various concepts, optimizing solutions, and being familiar with design patterns, you can showcase your proficiency in this critical area and develop software that efficiently manages large amounts of data, handles complex logic, and scales effectively.

Even though I hate the current trend of asking direct leetcode questions. DS Algo is still needed for understanding optimal ways to implement any requirement. Most of the time you don't need to implement the DS itself, or write the implementation of the algorithm but if someone has some understanding about them it marks a great starting point for researching how to optimize the current approach.

Coding interviews for enterprise software positions often include a wide range of topics, the areas listed below should be covered in order to prepare for the interview. * Data structure and Algorithms * Good understanding of design pattern * System design * Problem solving * Object oriented design * Performance optimization

Algorithms: Sorting, sliding window, hashing, binary search, recursion, reversing a linked list, tree traversal, and graph algorithms Data structures: Arrays, strings, binary trees, dynamic programming, and linked lists Linear data structures: Linked lists, arrays, queues, and stacks Nonlinear data structures: Graphs and trees

Be sure to have a strong understanding of algorithmic complexity and the best algorithms to solve certain solutions in the most efficient and optimal way. With Cloud Computing bringing about microarchitectures, it's also vital to understand how data structures work together under the hood so you can use things like Queues, Tables, Buses, etc. when creating cloud solutions.

Be prepared to be given a database schema and write queries of various degrees of complexity. Also be prepared to discuss how you sit down and design a database from scratch. Know Normalization and Demoralization and the benefits and users of each. Know how indexing works and affects the execution plan for a query.

Reverse a linked list Find the longest common substring of two strings Implement a binary search tree Implement a hash table Find the shortest path between two nodes in a graph Write a function to deep copy an object Write a function to serialize and deserialize an object Design a class hierarchy for a particular domain Write a function to test the validity of an IP address Write a function to encode and decode a base64 string Write a function to implement a simple calculator Write a function to parse a JSON document Write a function to generate a random password

In Enterprise Software development, proficiency in database design and SQL is vital. SQL is the universal language for managing relational databases, a cornerstone of enterprise data storage. Developers must excel in creating tables, crafting relationships, querying, joining, filtering, aggregating, and performing CRUD operations with precision. Additionally, the skill to design an efficient database schema, considering factors like normalization, indexing, foreign keys, and triggers, is crucial for meeting specific requirements and constraints, ensuring data integrity and accessibility in enterprise systems.

Database Design and SQL for Enterprise Software Developers Database design is the process of creating a database schema that meets the requirements of a given application. It involves identifying the data entities, defining their attributes, and establishing relationships between them. The goal of database design is to create a database that is efficient, scalable, and easy to maintain. Here are some of the key database design and SQL skills that enterprise software developers should have: Database schema design Normalization Indexing Foreign keys Triggers Joins Subqueries SQL skills

Proficiency in web development and APIs is essential for many Enterprise Software solutions, as they leverage web technologies to deliver functionality and interfaces. This requires familiarity with HTML, CSS, JavaScript, HTTP, REST, JSON, and XML. Developers should be adept at creating and consuming APIs using tools like Postman and frameworks such as Express, Flask, Django, or Spring Boot. Key responsibilities include addressing authentication, authorization, validation, error handling, and robust testing to ensure effective web-based solutions in the enterprise domain.

System design and architecture are critical skills for Enterprise Software developers. It involves creating reliable, scalable, secure, and maintainable systems. This requires a holistic view of components, services, interfaces, protocols, and patterns, along with an understanding of how they interact. Non-functional requirements like performance, availability, fault tolerance, security, and modularity must also be considered. These skills enable the development of robust and effective enterprise solutions.

One website I read about was interview it.com There is no golden rule to guarantee whatever you get on the internet is authentic. So books on the top as applicable to the programming language you are using is helpful

System design and architecture is the most important part of any real life problem. But personally I don’t think this part should be important for all levels of roles. This part should be emphasized based on the experience level of a role. Nothing is perfect. I mean we can’t make anything perfect. We have to find a optimal solution for certain set of problems.

Pick 1 or 2 domains and gain in depth knowledge or understanding Be updated with current trends, emerging technologies as applicable to each domain Be prepared to talk about a used case

When interviewing software engineers for our enterprise-grade digital banking app built with React, our exercises help to evaluate 3 things: 1) Testing automation mindset/mastery 2) Skills to separate concerns (SoC principle) 3) Communication and teamwork skills These are critical for working effectively on the enterprise-grade software project.

For interviewers: Jumping into coding challenges without even saying hello is a common experience in interviews nowadays. It's like they care more about solving puzzles than knowing the person. I had an experience where they tossed a coding problem at me without any exchange of greetings. I believe there's more to hiring than just mastering LeetCode problems. Let's make interviews fairer by considering the whole picture, not just coding skills. Read the resume at-least for god's sake.

Be a good code reader, every time you are reading other people's code. Understand fast and change line of codes with testing is a good appractice.

- Live Coding: You may be asked to write code in real-time, often sharing a screen with the interviewer. The tasks might involve implementing a specific algorithm or function. - Whiteboarding: You could be asked to design a system or solve a problem on a whiteboard, explaining your thought process as you go. - Code Review: You might be given a snippet of code and asked to critique it or suggest improvements, testing your ability to read and understand code quickly. - Problem-Solving Discussions: Interviewers may present you with hypothetical scenarios or past problems they have encountered and ask how you would approach solving them.

In Enterprise Software interviews, expect Object Oriented Programming (OOP) exercises like class design, inheritance, design patterns, interfaces, and error handling. Prepare to apply OOP principles practically, and be aware of what principle to use in specific scenarios.
