Got OA with 3 sections. 1 coding challenge is relevant to the job description. The other two didn't match the skills/bg requirement in the job description. Compared to other MLE/AS jobs in big-name companies, this company seems to care more about your familiarity with data science tools like SQL and Pandas. Although they require a lot in math/physics/CV, all of these didn't show in their OA.

The first round seemed to be irrelevant to the job description posted. The three challenges were really difficult personally and required knowledge about things that were not mentioned in the description in the first place. It was an absolute time waste to spend time on this.
