Criteo Software Engineer interview questions

The process was divided into 4 interviews in this order: 1. Phone Screen (30 min): They talk to you about the company and ask you some basic questions about yourself. 2. Tech Screen (1 hr): You will be asked a coding problem similar to the style of Leetcode and you'll complete the problem. They'll modify the problem as they see fit and ensure you have basic coding knowledge. 3. Design Interview (1 hr): You'll be asked to design some software. The big point here is to talk about the different options and work together with the interviewer as if they're your buddy. It's not too hard but you do need to keep on task and have knowledge in design. 4. Behavioural Interview (1 hr): This interview is about your behavior. They'll ask you questions and you should respond using the STAR method. I didn't find this part difficult at all.

I interviewed for the Software Engineer position at "Mabaya - Criteo" after successfully completing a home assignment. The assignment involved implementing a REST API using Spring Boot, allowing me to work with any database of my choice while managing products and campaigns. During the interview process, I was asked a series of fundamental Java questions, which covered topics such as StringBuilder versus constructors, design patterns, and the implementation of the Singleton pattern. Additionally, there was a continuous discussion related to the home assignment.
