Two first-round technical data science interviews for two different roles within CVS Health. Both interviewers were very nice to speak with; however, their approach—and consequently, my impression—was completely different. 1. SQL Interview (should have been easy, right?) – Terrible experience! Three or four well-defined tasks were given. However, the partially written SQL queries and the lack of direction on whether I was required to modify the existing code or implement my own solution left me scrambling to debug the poorly written queries before even proceeding, as the original queries failed to run from the start. Oh, and the interviewer simply dropped the code into CoderPad, went on mute, and seemingly did other things, making it impossible to ask questions. 2. Python Interview – Excellent experience with the interviewer(kind & professional). The question was moderately challenging (LeetCode medium or a simplified hard), and although I wasn’t able to fully complete the solution in time, I was given a helpful hint along the way.
