Candidate 3 made a bad first impression, which immediately brought them into a negative starting position.
Their interview performance was just as good as Candidates 1 & 2, which ultimately left an overall positive impression.
But because they were starting from a negative base after their poor first impression they were behind Candidates 1 & 2 at the end of the interview.
This may seem obvious, but the diagram above nicely highlights the importance of a good first impression when interviewing for a job.
It really can be the difference between success and failure when there is a close field of candidates.
