The colloquium was composed of:

• Screening of CV and possible motivation letter.
• Tasks #1, which were an initial set of tasks mainly consisting of logic questions that were not extremely complex, and there may also have been questions related to the role.
• Tasks #2, which occurred if the first set of tasks went well, and included another set of tasks with some programming tests.
• Interviews, which were three rounds covering problem-solving, behavioral questions, and finally a role-related round with possible system design.

The first interview could be done in parallel with the second set of tasks. Good time management skills were strongly recommended for the tasks, especially the programming tasks. All in all, it was a good experience, and I will try again.
