Study routine
Make a focused 30-minute session
- 5 min: pick one concept and write down what you want to understand.
- 15 min: read the relevant note or guide and summarize the key idea in your own words.
- 10 min: answer a practice question or explain the concept without looking.
Use code carefully
Check an example before reusing it
- Read the assumptions: language version, inputs, and required libraries.
- Run it in your own environment and compare the output with the example.
- Try an empty value, a boundary case, and an unexpected input.
- Make sure you can explain each important line before adapting it.
Interview prep
Practise explaining your thinking
- Choose one project and explain the problem it solves and your contribution.
- Review the fundamentals behind your tools, then practise a few questions aloud.
- For each answer, give a clear example and mention a trade-off or lesson learned.
