1. Online assessment. - It started well--I solved all 3 coding questions and 90% math questions. 2. Technical Interview - They asked me a few coding questions + some python related questions. I performed good and went to the next round. 3. Next round... I expected questions about Python, some coding questions and maybe some elements of system design. But, instead, they asked me a lot of math questions. And I just was not prepared. There was nothing about math in the job description! The most disappointing thing was that my recruiter told me nothing helpful about the interview process. So, I had negative experience, and not because of engineers that interviewed me, but because the job description didn't match the actual questions, and my recruiter didn't tell me what to expect.
