How does coding interview work?

Evaluation Criteria

• Problem-Solving Approach:
  Candidates are evaluated on how they break down a problem and plan their solution.

• Coding Ability:
  Focus is placed on the candidate's ability to write clean, efficient, and error-free code.

• Time and Space Complexity:
  Interviewers assess whether the solution is optimal and scalable.

• Communication Skills:
  Clear articulation of thought process and logic is important.

Tools and Platforms

• Coding Platforms:
  Companies use platforms like HackerRank, Codility, or LeetCode to administer coding challenges.

• IDE or Whiteboard:
  Some interviews use an Integrated Development Environment (IDE) for live coding, while others rely on traditional whiteboard problem-solving.

Key Preparation Tips

• Practice Common Problems:
  Focus on arrays, strings, recursion, dynamic programming, and graph algorithms.

• Understand Patterns:
  Learn patterns like sliding window, two pointers, and divide-and-conquer.

• Mock Interviews:
  Practice with peers or on platforms to simulate real interview conditions.

• Behavioral Questions:
  Prepare for questions about past experiences and team collaboration.

Conclusion

A coding interview is a structured process designed to evaluate technical and problem-solving skills. Preparation and practice are essential for success, with a focus on writing efficient code and effectively communicating solutions.
