The interview process consists of 6 stages if your CV has been validated, including: Online Coding Test, First Video Interview, Second Technical Video Interview, Onsite Technical Interview, People & Culture Team Interview, and CEO Interview.
Online coding test: Codility problems to solve. I had two hours to solve two problems, which is sufficient as they are simple algorithmic problems.
First video interview: I interviewed with one HR representative and one member of the technical team. This is a typical HR round where I was asked about my background, motivation, and had the opportunity to ask several questions about the team & work.
Second technical video interview: This is an online interview with a developer where you have to solve a typical easy LeetCode problem. You are expected to explain your solution and also describe the time and space complexity. Expect some data structure-related questions if you use them in your solution. I also had extra time, so we discussed about various thing related to the company and the job.
Onsite technical interview: This is an on-site interview where you meet two developers from your potential future team. It lasts three hours. During these three hours, you are asked to implement a program through three sprints (45 minutes coding and 15 minutes discussing each sprint). You are expected to clearly explain your design choices and ensure your code is easily maintainable and testable. It is also expected that you test your solution by writing unit and integration tests. Even if you find an implementation that works, make sure to clarify any questions about the problem statement.
People & Culture Team Interview: This is a typical behavioral assessment step. While there are no right or wrong answers, it's important to prepare a few situations or scenarios from your recent work experiences to feel comfortable during the interview.
CEO Interview: This is a 20-minute interview where you are asked about your personal situation (which could include motivations or background). It is also an opportunity to ask any questions or raise any concerns you may have. Towards the end, you will be asked about your start date and salary expectations.
Overall, the people I met were nice and friendly. It is a lengthy process with several steps that require preparation.
