The first stage of the application process is a programming task.The candidate has 2 weeks to submit the task. It requires the candidate to implement some logic and optimize the existing code. The task is not trivial and is really fun. The hr representative has been quite fast to answer all the questions about the assignment (2/3 days to get an answer).

I solved the assignment successfully (the task comes with an automatic score system that shows the result of your optimizations/correctness of the bew features). I did't get an offer since both the assignment and the CV showed a lack of experience/skills (junior profile). They were super nice all the time and even explained to me why they choose not to take the application process further with a detailed email.
