‘First impressions are everything.’
‘I can tell after two minutes whether the candidate is right for the role.’
These views, I am afraid, are not the observations of experienced interviewers and mean that the interviewer is judging from a narrow perspective. The fact that a mathematical modeller presents themselves as a taciturn, verbally reclusive, monosyllabic candidate can be a positive indicator if you are seeking a highly numerate and technical analyst, whilst the energetic, verbose, gregarious candidate may be an excellent fit for that business development role you are seeking to fill.
We know that each situation is very different and the determinants that will influence the outcome are varied. Nevertheless, there are some general pointers that I can recommend and which you can adopt whilst assessing candidates.
Whether and how you validate and interpret first impressions will be dependant to the job criteria, the individual personality type of the interviewer and equally the personality type of the interviewer.
