Worth your time
What moves the needle
One or two finished projects on GitHub
FreeA working project with a short README and a live demo answers "can you build?" faster than anything else.
A structured problem list (e.g. NeetCode 150)
FreeCovers the common patterns timed tests use. Depth in one language beats breadth.
Visit sitePractise talking through code out loud
FreeAI interviews score how you explain, not just the answer. Record yourself solving one problem a day.
Reviewing code from open-source pull requests
FreeCode evaluation work is mostly reading and judging code, not writing it from scratch.
Coursera project-based courses (e.g. Google, Meta, DeepLearning.AI)
Low costGood structured learning, but only if you finish the hands-on project and put the working code on GitHub. Link the project, not the certificate PDF.

Usually a waste
Certificates of completion with no project
They show you watched videos, not that you can code.
Short "full-stack in a week" bootcamps
Too shallow to pass a timed test, and screeners know it.
Collecting many language badges
One language you know deeply beats five you know a little.

Questions
FAQ
Which language should I prepare in?
The one you know best. Most tests let you choose, and Python and JavaScript are widely accepted.
Is a Coursera certificate worth paying for?
The certificate alone rarely gets you through a screening. Audit courses for free where possible, pay only if you need graded projects, and finish quickly so a monthly subscription doesn't run on. What helps is the project you build and link on your profile.
Do cloud certificates help?
They can help for some infrastructure jobs, but for coding tests and AI coding evaluation, solved problems and projects matter much more.
