Seeking Guidance: Improving My Coding, DSA, and Linux Troubleshooting Skills for Career Growth

Hi everyone,

I'm currently working as a Cloud Engineer, and I'm seeking community guidance on two areas where I feel I need significant improvement to advance in my career.

1. Coding, DSA, Algorithms, and OS Fundamentals: During my college years, I didn’t focus much on coding, data structures & algorithms (DSA), or core computer science subjects like Operating Systems. Looking back, I realize this was a missed opportunity, as these skills are critical in most technical interviews. Python seems to be the most commonly used language in interviews and day-to-day tasks in cloud roles. Could anyone please recommend the best resources or platforms to effectively learn:

Python programming (from beginner to advanced)

DSA and algorithms

Operating System fundamentals Ideally, I'd like structured content that is interview-focused but also helps build strong conceptual understanding.

2. Linux Troubleshooting Skills: While I’m comfortable with basic Linux commands and daily usage, I often struggle with troubleshooting questions during interviews. I’m looking for practical resources, labs, or platforms that can help me sharpen my Linux troubleshooting and system administration skills in a real-world, hands-on manner.

Any guidance, course recommendations, or personal learning paths would be highly appreciated.

Thank you in advance for your support and suggestions!
