The interview has 4 stages. 1: Phone call with HR and then they send a Codility test with 3 coding questions that can be found here. 2: Technical interview with the team leader. Asked some normal interview questions 3: Technical interview with group manager. Asked normal coding questions and asked to code the answer. 4: Last HR round. As usual.

In stage 2 the team leader asked about linked list. I needed to find a loop, find the size of the loop, find where the loop starts, and find the size of the list.

In stage 3 the group manager asked about my university courses, personality, and some other questions. Technically he asked about creating a mechanism to check for every user if he got to his limit of X requests in T time. If he is, block him, else, do nothing.

In stage 4 the HR asked about my CV, in detail, and salary expectations.
