I was hired to help test a security system once. I was sent in to a semi-large company and had to go through a list of certain objectives. My favorite one was “take something out of the building that is too big to hide on your body.“ I paired it with “get into a secured facility within the building.”
I walked in in my general business getup. Shirt, tie, jacket, nice pants, not quite “suit” because it was all just a little bit shabby and not exactly matching but not clashing. Nice briefcase. Clipboard.
Getting into the secured part was easy. Learned the name of the supervisor, told the security guard that “Cindy said they’d let me in without a problem on my first day. Something about the badges not being made fast enough.” Sure, no problem, go ahead.
Walked in, unhooked a PC tower, walked to the bathroom where I’d hidden a dolly earlier, went into a stall and changed into the outfit I’d had in the briefcase. It was what I’d consider workman’s clothes but a worker in an office, not like a construction worker.
Blue jeans, t-shirt, worker’s vest (low key), hat, good boots but 2nd hand.
Threw the tower on the mover’s dolly with a couple other things, stacked very slightly precariously but not likely to fall, walked over to the stairs leading down, and started going down to the way out, which I knew had a security guard on it.
As soon as I saw him see me I stumbled and yelled out. He came running over and helped stabilize everything. Helped me down the stairs. Held the door open for me and told me to “have a nice day” as I left. Never asked for my badge or even where I was going with the stuff.
Act like you know what you’re doing. Look like you belong. Be confident.
That’s 75% of it right there.
