Interview Process

The interview process consisted of several rounds, including a coding challenge, a machine learning bug bash, a hiring manager screen, and a system design interview. The coding challenge involved sending emails based on subscription tiers, with follow-up questions about handling expirations and updates. The machine learning bug bash focused on identifying three errors in a code snippet, where the candidate noted the importance of using a debugger. The hiring manager screen included in-depth questions about past projects and behaviors. The system design interview revolved around predicting account takeovers, requiring clarification on the use case and discussing various sampling methods.
