At times, getting a first job gets delayed for reasons beyond our control. To find out the answer to your question of not getting a job so far, you have to do some homework if others have to help you. Please note down the questions you were asked and the answers you gave or could not give.
It is like our school or college days. After we come out of the examination hall, we compare and share our answers with our classmates. Such discussions will give us an idea of the correctness as well as an indication of our performance in general. A similar exercise will have to be done now.
We may be thinking that we have done very well until someone points out how it could have been done better. Once you collate the information as above, please take the details to a well-wisher who has the experience. He will guide you. This will refine your future performances and increase your chance of doing well as well as getting selected.
I wish to point out certain things about your posting. You have to pay attention to the language. Write the words in full. Use capitals where necessary. Write small and complete sentences. See what all you can do to make your posting simple, better, and clear.
Wishing you good luck,
Regards,
