Top 6 Coding Test / Interview Tips (Code Test) смотреть онлайн

TL;DR: IDE, unit tests, debugging, HackerRank/LeetCode, organize, positivity

1. Be Comfortable with any IDE
-Get comfy with an IDE (Integrated Development Environment) of your choosing
-It can be IntelliJ IDEA, PySpark, Eclipse, BlueJ (ok maybe not BlueJ)
-It shows initiative, and let’s face it as a developer you’ll be living in an IDE all day
-Has lots of features like auto imports and intellisense (suggestions/line completion)

2. Practice Creating a Unit Test
-This can be in Junit (for Java) or PyTest (for Python)
-Just know how to create a unit test in the IDE of your choice, and practice it
-Unit tests are expected of developers
-Start easy, how to do a simple assertion
-Work your way up to parameterized test, then mocking classes (like I said start with easy)

3. Practice Debugging
-Know how to debug a method in your IDE
-Set breakpoints
-Set watch values
-Know how to step into, step over, step out during a debugging session

4. Create accounts on HackerRank and LeetCode
-You may be asked to use HackerRank or LeetCode during your test, you want to have a good feel of their UI (User Interfaces) ahead of time
-These are also great training resources.
-HackerRank is free to use to learn many languages - more advanced that w3schools. Go to: HackerRank ... Prepare ... Java or Python, etc…
-LeetCode is free to look at problems and some solutions - the icon next to the solution indicates if it’s unlocked. Go to: LeetCode ... Problems ... Top Interview Questions

5. Organize Your Response/Solution
-Start with reading the problem, what are the inputs, outputs, and rules
-Add comments, and sketch out some potential methods you could use
-Work on the logic, and will fill in the actual code afterwards
This shows you have a strategy (algorithm) to solve the problem
-Avoid writing code too quickly, since you’ll get mired in syntax, data types, and the IDE, instead work on architecting a possible solution.

6. Stay Positive
-Stay positive, good humored, the interviewer is evaluating how you go about solving the problem and your attitude
-If the person being interviewed expressed frustration, that will reflect poorly, …would you want to work with a frustrated person or with a person with a more tempered attitude?
-The interviewer may offer hints if you’re struggling, be gracious, and accept the help!
