I meant to reply to this and got sidetracked by making dinner, lol.
I have had a few friends that have competed on the cooking competition shows like MasterChef and Top Chef. A lot of it is staged, a lot of it is managed for extra drama. There are whole story lines throughout the season that are created through selective editing and whatnot -- like rivalries between cooks and things like that.
But as for getting it onto the plate with a minute left, yes you can do it if you're organised. A HUGE part of professional cooking is timing. If you're making a dish, say a burger, you start the patty first because it takes the longest, you drop the fries with about four minutes to go, toast the bun and do the set in the last minute, and if it comes with a salad you do that at the very last so it's fresh. Nothing worse than having a salad sit up for 10 minutes while the rest of the food is cooking, or having your fries go cold because the burger's not done yet. Everything should be done at exactly the same time, and all go on the plate at once. That seems doable for one plate, but try coordinating 150 plates an hour on a busy Friday night with a crew of ten cooks. That's what I did for most of my life.
I don't watch those shows much anymore because I can spot the editing and the staged stuff, and it drives my wife crazy because I keep up a running commentary about how fake it is.
Cooking in restaurants is very difficult to do consistently well, and if you go out and get a really good meal, send your compliments back to the kitchen. It means a lot, and the ones who take pride in what they do will appreciate it.
