After the candidate qualifies the written test he/she will be called for the next level of testing i.e. interview test , on the basis of that interview test the mind of the candidate is judged.

__Interview Test__** :**

- The Union Public Service Commission will declare a qualified list of candidates (based on the written exam).
- The selected candidates will appear before a Services Selection Board for Intelligence and Personality Test.
- Candidates for the Army/Navy wings of the NDA and Executive branch of Naval Academy will be assessed on officers potentiality
- Candidates for the Air Force wing, along with officer potentiality assessment, will also undergo a Pilot Aptitude Test.

After this Qualified candidates will then be placed in the final order of merit on the basis of total marks secured by them in the Written examination, and the Services Selection Board Tests in three separate lists:

**Army and the Navy,**

**Air Force**

**Executive course at the Naval Academy.**

The names of candidates who qualify for all the Services of NDA and the Naval Academy will appear in all the three Merit Lists.

The final selection for admission will be made in order of merit depending on the number of vacancies in each wing.

Thus in order to seek career in NDA 2017 ONE SHOULD DO HARD LABOUR, if you are positive and your determination level is high then you can crack it easily. Everything depends upon you how you take it and how you leave it.
