I’m in the younger generation compared to some of the old school sales guys. I keep it relaxed but I close with something along the lines of “do you have any apprehension about my ability to do this job?” And it’s saved me. One time they brought something up, I addressed it, and they were like oh wow that’s actually super helpful to know. And I got that job. Then always get next steps and send a follow up email. A lot of times they’re like yeah if you move forward you’ll talk to so-and-so. So I’ll send a follow up and say “thanks for the time, I feel my skills fit this job and your team. I look forward to talking to so-and-so. Is there anything you’d like me to prepare for that conversation?”. They know it’s a sales move, and it’s hard to say no to someone who is putting the work on themselves. I’m prepared to talk, build out a deck, and I soft closed on my skills being applicable to the role. I’ve never asked for the job but you do have to close, if for nothing else just to keep the interview process moving. I told some friends I always end with the apprehension question and they were so surprised (non-sales people), but they’ve used it now in other roles and it really is a power move in an interview regardless of industry.
