45 mins online assessment, math heavy, did 5 questions correctly atleast, invited to a zoom interview. They ask about everything on your cv, be prepared to be asked about hard core maths.
Interview began with a math online assessment: 7 questions in 45 minutes. Next, a first-round technical interview on Zoom lasting 60 minutes, focused on problem-solving, coding, and clarifying thought process.
