      Application

      I applied online. I interviewed at Proto (Canada) (Waterloo, ON) in Jan 2026

      Interview

      The interview began with introductions and location confirmation, followed by my introduction. The discussion then moved into a Q&A format covering various DevOps domains. The interview included scenario-based questions on deploying applications, managing SSL certificates, differentiating between AWS Aurora and RDS, and troubleshooting database performance issues related to CPU utilization, throughput, and connection pooling.
