No selection process can ensure a substantial, guaranteed end-product. The period of examination will invariably be short and it will sometimes provide only a snapshot of the candidate's potential. However, past history, and the candidate's record of development, will also be a very useful initial guide. Aptitude testing can give notice of the candidate's suitability for an aptitude-dependant branch and then further assessment, by interview and additional exercises, will help to ascertain the candidate's  overall  profile.  At  interview,  close  examination should reveal the following qualities and traits:

a. Appearance and Bearing. The candidate's appearance, bearing, grooming, distinguishing features and general presentation should be readily apparent within the first impressions formed at interview.

b.   Manner   and   Impact.   The   candidate's   conduct throughout   the   interview,   along   with   his   courtesy,   tact, confidence, force of personality, presence, poise, polish, humour and alertness will add to the overall impact.

c. Speech and Powers of Expression. Dialogue with the candidate will elicit his ability to communicate. The quality of grammar, vocabulary, diction, general fluency, logic, projection and animation will all indicate the overall effectiveness of expression.
