11) Problem-Solving Ability

Problem-solving is an integral instinct of a web developer and the company wants there employees to solve real-world problems.


I use this four-step approach to solve the problems:-

  • Define the problem

    First of all, read the problem carefully, and see what this problem wants.

  • Analyse the problem

    Analyze the problem and see what is the solution that this problem wants and try to write a solution for that.

  • Implement a solution from the analysis

    Try to read your solution and implement it.

  • Evaluate your implementation

    Evaluate your solution and see if your solution can pass all the test cases and if not then again define your problem, analyze it then implement and then evaluate the solution.
