Think or improve my perception to the problem or logic?

Hi Nilkamal, these skills come with experience.

The more you develop, the more problems you encounter. This improves your way of viewing the problems at hand.

But also with more experience I believe its safe to say that you had your share of fails and funny thing about them is that they also improve you. For example at some points you probably have/will encounter some specific problem that was hard to solve (or maybe even unsolvable) and you realize that you gone with a wrong approach (design). Due to these kind of fails you are able to anticipate if some current design of yours will be able to handle some future requirements that are similar to previous ones that you encountered.

So in short practice makes perfect and I would suggest you to start with www.testdome.com. This site offers quite a lot of publicly available programming tests, see here:

With them you can improve your skills, note there are various types of tests, like troubleshooting, algorithmic thinking, problem solving, etc.

Also as an FYI you can even get a free programming certificate if you're able to solve their tests with good score.
