At the conclusion of your interview, you can wrap up any unfinished business you failed to cover so far, and begin to explore the future of your candidacy.
During your interview wrap-up, it’s a good practice to make the interviewer aware of other opportunities you’re exploring, as long as they’re genuine, and their timing has some bearing on your own decision making.
The fact that you’re actively exploring other opportunities may affect the speed with which the company makes its hiring decision. It may even positively influence the eventual outcome, since the company may want to act quickly so as not to lose you.
However, your other activity should be presented in the spirit of assistance to the interviewer, not as a thinly veiled threat or negotiating tactic. I’d advise you to play it straight with the interviewer.
And remember to maintain a positive attitude. In today’s job market, you’d be surprised how often victory is snatched from the jaws of defeat.
The better your interviewing skills, the greater your chances of getting the job.
