Altran Interview Experience for Full Stack Developer
Application Shortlisting
Initially, the eligible candidates submitted their resumes, and the final list of shortlisted ones was shared within a few days.
Online Coding Test
An online coding assessment was conducted but this was more of a subjective type. This, in a way, seemed that the company was interested in the student’s analyzing skills rather than just coding.
Questions:
- Implement a function to check if a given string is a valid palindrome, considering alphanumeric characters and ignoring cases.
- Write a program to merge two sorted arrays into a single sorted array.
- Create a simple REST API endpoint using a backend framework (e.g., Express.js, Django).
- Design a responsive web page layout using HTML, CSS, and JavaScript.
Technical Interview (First Round – Medium Difficulty)
Candidates who clear the online coding test proceeded to the first technical interview with a member of the Altran engineering team. The interview assessed the candidates’ technical proficiency in full-stack technologies, data structures, and algorithms (DSA).
Sample Questions:
- Explain the Model-View-Controller (MVC) architecture and its benefits.
- Discuss your experience with a front-end framework (e.g., React, Angular) and a back-end framework (e.g., Node.js, Spring Boot).
- Solve a problem involving linked lists, such as reversing a linked list.
- Describe a project where you implemented a full stack solution. What technologies did you use, and what were the challenges?
Technical Interview (Second Round – Medium Difficulty)
Candidates who pass the first technical interview went a second technical interview with another member of the Altran engineering team. This further evaluated the candidates’ technical capabilities and delve deeper into their understanding of full stack development and previous projects.
Sample Questions:
- How do you manage state in a React application? Discuss the use of hooks and Redux.
- Explain how you would design a RESTful API for a book store application. Include endpoints for CRUD operations.
- Solve a problem involving tree traversal, such as finding the depth of a binary tree.
- Discuss a previous project where you faced performance issues. How did you identify and resolve them?
