Sample answer
“In my previous role at a local tech company, I wrote several Bash scripts to automate server backups and system monitoring. One script I created checked disk usage and sent alerts if it exceeded a certain threshold, which helped prevent system outages. I tested these scripts rigorously in a staging environment before deployment. This experience taught me the significance of automation in improving operational efficiency.”
