Take-Home Assessment Practice Tips

1. ⏳Use a timer: Set a timer for the amount of time you have to complete the coding exercise. This will help you get used to working under time pressure and help you stay focused during the exercise.
2. 💻Choose a suitable platform: There are several online platforms available for practicing coding exercises, such as HackerRank, LeetCode, and Codewars. Choose a platform that you are comfortable with and that offers timed coding exercises.
3. 🖊️Start with easier problems: If you're new to timed coding exercises, start with easier problems to get used to working under time pressure. As you gain more experience, you can gradually work your way up to more challenging problems. See the video here.
4. 📚Mimic interview conditions: Try to simulate the conditions of a real coding interview as closely as possible. This means working in a quiet environment, avoiding distractions, and using only the resources that you would have access to during an interview.
5. 🔍Read the instructions carefully: Before you start working on the assignment, carefully read through the instructions to make sure you understand the requirements and the deadline.
6. 🧾Break down the task: Break down the task into smaller, manageable parts. This will help you focus on one task at a time and make it easier to manage your time.
7. ⌚Prioritize your time: Prioritize your time to work on the most important parts of the assignment first. Set a timer for each part of the task. This will help you keep track of how much time you're spending on each part of the assignment and ensure that you stay within the time frame. This will help you ensure that you have enough time to complete the essential parts of the task before the deadline. See the video here.
8. 📱Avoid distractions: When working on the assignment, try to avoid distractions as much as possible. Turn off your phone, close any unnecessary tabs on your computer, and find a quiet place to work. See the video here.
9. 🖥️Test your code: Once you've completed the assignment, test your code thoroughly to make sure it works as expected.
10. 📝Analyze your performance: After you've completed a timed coding exercise, review your code and evaluate your performance. Identify areas where you could improve and make note of any mistakes you made. This will help you identify patterns and develop a strategy for improving your performance in timed coding exercises.
11. 📩Get feedback: If possible, get feedback from someone who is experienced in software development. They may be able to provide you with valuable insights and suggestions for improvement.

Tips for Communicating Your Thoughts About the Process

Communicating your thought process is just as important as solving the problem itself, as it shows the interviewer how you think, approach problems, and communicate your ideas effectively.

To start, paraphrase the problem in your own words and identify the requirements and constraints. Break the problem down into smaller parts and explain your plan to tackle each one. This will help you stay organized and ensure you don't miss anything important.

As you work through the problem, keep explaining your thought process out loud. This can include reasoning behind decisions, potential solutions to errors, and any assumptions you make. When you have a solution, take the time to walk the interviewer through your code. This is your chance to show off your technical skills and explain how your solution works.
