Interview Questions & Answers
1. Purge Empty Folders
Learn how to safely identify and remove empty directories from /tmp using Linux Bash commands. This guide covers recursively scanning for empty directories, filtering to avoid occupied ones, and automating cleanup, essential for preventing inode exhaustion, maintaining filesystem health, and reducing storage fragmentation in production systems.
2. Restore Blocked SSH Access
Learn how to diagnose and restore firewall access for SSH using Linux Bash commands. This guide covers identifying active firewall systems, inspecting current rules, adding inbound SSH permissions, reloading configurations, and verifying connectivity, essential for troubleshooting locked-out SSH access and managing firewall security in production environments.
3. Debug Service Crash Loop
Master systemd journal monitoring for diagnosing service crashes and crash loops in real-time. Learn how to live-follow systemd service logs, capture crash sequences with full context, identify application errors during rapid restart cycles, and extract root causes from journal output. This guide covers using journalctl for real-time log streaming, correlating application errors with systemd restart messages, capturing multi-cycle crash patterns, and troubleshooting services that fail during initialization. Essential for debugging microservices, identifying port conflicts, SSL certificate issues, and rapid failure loops in production environments.
4. Stage Only Specific Files
Create focused commits by selectively staging specific files instead of all changes. Stage app.js and style.css separately from config.json, maintain separate concerns in different commits, and organize changes logically. Essential for atomic commits, focused pull requests, logical grouping of related changes, and preventing unrelated modifications from being bundled together.
5. Undo Commits but Keep Changes
Undo premature commits while retaining all modifications for reorganization. Use soft reset to move branch pointer backward, preserve changes in staging area, and recombine commits logically. Essential for reorganizing commit history, fixing premature commits, splitting commits into better-organized groups, and maintaining work while improving commit structure before pushing.
6. Inspect TLS Certificate Issuer and Validity
Inspect a TLS certificate to extract its issuer and validity period before a service goes live.
7. Input Field Validation
Master input field validation with Selenium. Learn basic input finding and property checking for beginners....
