Riiid Labs interview questions

Online problems were given and solution snapshots were asked to upload. After evaluating the solutions in approx 2 days and got reply about the selection and after consenting the service agreement.

A recruiter called me and talk about my past work experience and why I want to change the job. Then I got a 2 hours online test from Hackerrank. It is about 4 questions, but only one leetcode-like question (count number of subsets of a list which satisfies specific requirement). Other questions are data I/O, query, and ETL python questions.
