Why do ramblers not get the job?
For starters, having been a participant in mind-numbing meetings and conference calls, no one, and I mean no one, likes the person who wants to drag the meeting out an extra 40 minutes with additional questions, commentary, or just to hear them talk. That makes most sane people want to seriously injure the person.
Secondly, it shows that you are easily distracted and will have challenges sticking to task. It shows that you are not confident in your responses.
The last reason is that if you don’t answer the question at some point, the interviewer has no idea where you are going with your response!
So…instead of answering the question with what you think your interviewer wants to hear (like a bunch of unrelated buzz words jammed together nonsensically), answer the question directly and briefly. Then stop talking. Let the interview probe further if they are interested, or ask you another question to keep the interview moving along. Let the interviewer set the pace. Although being nervous typically encourages people to be chattier, stopping to let the interviewer know it is time to move along allows a comfortable timeliness, and may encourage a good two-way conversation between both of you. And that’s always a good sign!
