Entrevista
I got a HackerRank test invitation email with no details on the due date of this test or what kind of questions would be asked: whether it was going to have data science related questions or coding questions. I did not get any email from a recruiter to reach out either. The Hacker Rank test had several issues: formatting issues with questions, incorrect question, all multiple choices offered for a question were wrong, etc. Questions were multiple choice; one coding question
