Case · hiring

Brasa Demo is a fictional burger restaurant. People and figures are illustrative.

The Friday the grill cook quit

The problem

Friday, 18:40. The grill cook texts that he is not coming back. The shift starts in twenty minutes.

The usual

A Facebook post, forty messages, and the first person who shows up gets hired. Three weeks later, again.

What fixed it

Impulsa had the role defined, the candidates in one format and the interview prepared.

$17,287the cost of one bad hire

Six busy shifts with the grill short-handed, thirty hours of the owner's time and three weeks of badly portioned beef. And the role is still empty. One location, ~520 checks a week, $260 average check, in Mexican pesos. Assumptions are shown further down.

Saturday, 9:00. The gap already has a name and an amount.

Brasa's owner covered the grill on Friday. Before bed she opened Impulsa, picked the role and marked what matters most to her. By morning there was somewhere to start.

This is how hiring almost always goes. Twenty-one days and back to the start.

This story has no villains. It has hurry, a phone full of messages and no way to compare one person with another.

Friday

The grill cook does not show. The owner puts on the apron. Ticket times double and two tables walk out.

Saturday

Facebook post: Experienced grill cook wanted. Message us for details.

Sun to Tue

Forty messages. Info. How much does it pay? Photos of résumés taken sideways. Two-minute voice notes. All mixed in with supplier orders.

Wednesday

Six invited. Two show up. The interview lasts as long as it takes an order to come out.

Thursday

When can you start? Today. Hired. Nobody called his last job.

Week 2

He learns by watching. Nobody taught him the portion weight: he serves 131 g where the recipe says 120. His paperwork is still pending.

Day 21

Saturday, 18:40. He does not show. The Facebook post is still up. It gets shared again.

Sales that never happened6 busy shifts × 8 fewer checks × $260 × 65% margin over ingredients	$8,112
The owner's time30 hours across messages, interviews and the grill × $200	$6,000
Extra beef while he taught himself11 g × 650 burgers × 3 weeks = 21.4 kg × $148	$3,175
Cost of a hire that did not last	$17,287

Illustrative assumptions, all in view. For reference, the published pay for a cook in Cabo San Lucas is about $11,103 a month (Indeed, July 2026): this total equals 1.6 months of that pay.

Module · Impulsa · Hiring

The same candidates, in one format.

The role comes from a library of more than 3,000 roles and 13,500 skills. The owner marked four priorities. Candidates sent their résumé by WhatsApp or by voice, and each one landed in the same brief.

A useful summary with the evidence at hand. The brief does not score anyone: it organizes what each person said and flags what is left to ask.

The AI does not decide who to hire. Your team does.

With the briefs ready, the interview is no longer improvised between orders. The questions come from the priorities the owner marked.

Interview guide · Grill cook

Show me how you portion 120 g without a scale. Now with one.
Saturday, 21:00, fourteen tickets in the queue. What goes out first?
How do you leave the grill at close for whoever opens tomorrow?
For Karla: why did you leave La 20?

Next: references and skills checked before the second interview.

With Impulsa: 2 shifts with the grill short-handed ($2,704) and 8 hours of the owner's time ($1,600). Difference: $12,983. This is an example, not a customer average.

Second act

On the floor, hiring in a hurry shows up in the check.

Sofía started three weeks ago, the way the previous grill cook did: no profile, no guide and no onboarding. Same menu, and her average check sits $46 below the floor average.
