The interview process began with a recruiter screening, followed by an online assessment. This assessment was similar to an algorithm test but more realistic.
If you passed that stage, the next step was "Block 1" interview. This interview consisted of a 45-minute behavioral component, followed by a 1.5-hour technical section that included both algorithms and behavioral questions.
Finally, if all previous stages were passed, candidates proceeded to a "Block 2" interview, which focused on systems design. This interview was open-ended, with no single right or wrong answer. Preparation and the ability to justify your choices were key.
Throughout the process, there were several "logic" tests requiring candidates to identify the next pattern in a given sequence. While I found these tests a bit silly, they were not difficult.
My recruiter was very engaged and encouraging throughout the entire process, providing hints and tips before interviews.
