To up-skill its the best resources that matter and instead of pondering over which resource to pick and dedicate to try these, I have personally used most of them during my prep and even had some of my friends/colleagues talk about them.
→ Cloud :
- AWS Skill builder — Try out different learning paths, I followed and worked on the following: DevOps Engineer Learning Plan & Database learning path: AWS Relational Database Services. Try to check it at lnkd.in/gWxPT2bK, I can vouch for them as it would be one of the very best resource one could find for AWS kickstart and they do drop you at an semi intermediate level of cloud and AWS services, rest being with experience and practice.
→ DSA :
- Though opinionated I followed this technique to improve my problem solving and I saw many of my friends do great with it.
Started with choosing a language — #java. For basics I followed lnkd.in/gmktU4Zz. Once over with the basics its time for the libraries, in my case it was java collections. I referred the following resources for java collections and added generics: (once you learn collections in java, you are set to do java development too) lnkd.in/giAJ6pmz start with this and progress with an eBook called as java collections and generics. I guarantee things would be way brighter than before, because you would end up learning design patterns and many optimizations.
Coming to the dsa/daa part I used to refer Interview Cake web material topic wise and used to solve problems from 450sheet of that relevant topic. This was continued till some basic topics with the help of OpenGenus Foundation blogs over arrays, LinkedList and such. Moving to the advanced concepts I used to take help with Raj Vikramaditya playlist on YouTube for visual thought process like the DP/ tree/ graphs and such. (personal suggestion — try to make a GitHub repo and push your codes to it, incase you are solving some sheet try naming a GitHub repo with the same and make uploads). (Personal take — don’t fret over CP/Opensource while preparing, its just that not every one is born for sprints and marathons, but it isn’t the case that you skip walking, best way is to interact with people of varied walks of life, attend Raj Vikramaditya and Kunal Kushwaha streams/ content to explore fields).
→ Projects : Projects can vary may it be depending on your Techstack or criteria but some astonishing products to build are the ones that millions use. May it be docker/ git/ databases and such. refer Build Your X GitHub repo for the same and try playing with it. Python projects: lnkd.in/gJTiNa2T Java Projects: Open source projects are the best way to work your portfolio for java. WebDev — Many Udemy or course have capstone projects ranging from initial coding to deployment. DevOps — Follow Ann Afamefuna for her content posts as she is a great curator of DevOps projects and resources. Will love it.
