2,000+ Stores, 125,000 Applicants, 16 Recruiters: How Mattress Firm is Closing the Gap With Alex

Candi Thomas is Head of Talent Acquisition at Mattress Firm, the nation's largest mattress specialty retailer, where she hires for more than 2,000 commission-sales stores. Her team was already strong, with a time to fill around 35 days, but a human ceiling meant they could reach only about 9,000 of the 125,000 people who apply to stores each year. In a regional pilot, the team put first-round outreach on Alex, their AI recruiter. Nearly two-thirds of invited candidates now complete an interview, someone who applies at 3pm on a Friday is spoken to before Monday, and none of it requires a new recruiter or a new system to learn.

"I was skeptical in the beginning like most Enterprise TA leaders, but you have to keep getting better, and Alex matched a need we had. Glad we pushed past the initial fear!"

The Customer

Mattress Firm is the largest mattress specialty retailer in the country, with more than 2,000 stores, and it hires nearly 2,000 people a year to staff them. Candi Thomas, Head of Talent Acquisition, is responsible for hiring across stores, corporate offices, and distribution centers, plus  two other groups within the family of brands. Her roles are unusual for high-volume retail: sleep experts, assistant store managers, and store managers are all professional commission salespeople, not your prototypical hourly retail employees, so the bar for fit is high and the wrong hire is expensive.

Candi came up through the stores before moving into recruiting, and has spent years in high-volume environments, including one retailer that hired close to 100,000 people a year in a single holiday window. That background shapes how she thinks about the work: how do you move a lot of people through a process quickly without letting anyone fall through the cracks?

"Retail has been my entire career, but I started out on the store side. This is the first time I've ever been in a situation where the hourly associates are actually professional commission salespeople. It's a different style of recruiting than I've done before," Candi shared.

The Challenge

The problem was never a shortage of applicants. It was the arithmetic of a human team against a funnel that size.

A funnel far bigger than the team could ever talk to

Around 125,000 people apply to Mattress Firm in a year. At full human capacity, a 16-person recruiting team could hold real conversations with about 9,000 of the store applicants. The rest got no conversation at all, even though many could have been qualified and nearly all of them were potential customers of the brand.

The best candidates could not get on a full calendar

Recruiters were often booked two or three weeks out. An interested candidate would wait, then accept another job before anyone could reach them. Because calendars filled with the applicants who looked good first, a genuinely strong candidate further down the pile would not get a slot at all.

No headcount to buy the way out

Reaching another 20,000 people would have meant roughly doubling the size of the recruiting team. Adding additional headcount was not an option so the gap had to be closed using some other means, or not at all. As Candi shared, "You have 40 people apply, you find the first five that look great, and you think, I can always come back to the others if needed. The position might get filled or other needs may pull you in other directions and you never get back to them. Those people received a polite email, but never had a chance to speak with anyone."

The Solution

Mattress Firm adopted Alex on one firm principle, the one Candi used to bring skeptical business partners along.

‍An added step, not a replacement

The internal case was never that AI would do the hiring. It was that Alex adds conversation where there had been none, and that humans still make every decision. That framing is what moved the business partners who were cautious about AI being part of the hiring process or may have assumed candidates would refuse to talk to AI. Recruiters kept the cases that needed a person first, prior employees, opt-outs, and standout resumes worth a personal call, while Alex took the mass top of the funnel.

No new system for recruiters to learn

Workday, Mattress Firm's ATS, stayed the record of truth. Recruiters did not adopt a second tool or change where they work, they simply saw more candidates arrive already interviewed, and learned two new pieces of terminology, "Alex scheduled" and "Alex interviewed." The change management that Candi expected to be the hard part turned out to be nearly nothing.

Reaching applicants within minutes, on their own schedule

Alex picks up new applicants who clear the inline assessment and reaches out within minutes, staying persistent across several attempts by email and text. Interviews run by phone whenever the candidate is free, including nights and weekends, so contact no longer depends on a recruiter and a candidate happening to be available at the same time. Each completed interview comes back with a category-level assessment and a full transcript.

Ending the conversations that were never going to work

One behavior Candi did not fully expect is how cleanly Alex closes out conversations that are not going anywhere. When a candidate lacks the availability or the appetite for a commission role, Alex names it directly and asks the candidate to confirm. People leave those conversations without feeling dismissed and Mattress Firm recruiters don't spend time on candidates who do not want the type of role they offer. Candi was impressed, "There have been times where Alex has handled difficult conversations with more ease and confidence than I think some of our human recruiters could."

The Results

The pilot is young, so the early read is about reach, speed, and reception, not retention or quality of hire, which Candi expects to measure once there is more time on the clock.

109 candidate interviews in the pilot's first weeks

Alex completed 109 interviews, with volume settling around 20 per week. That is more conversations than the recruiter covering those roles could have run in the same window.

2/3 of invited candidates complete their interview, so far

Nearly two-thirds of the candidates Alex reaches out to finish the interview, higher than the team expected from cold outreach, and a sharp contrast with a process where most applicants previously didn't get to speak with anyone. Interviews run by phone on the candidate's own schedule, so someone who applies at 3pm on a Friday can be interviewed before Monday.

Assessments recruiters trust

When recruiters call to validate what Alex reported, the category scores line up with what they find. That lets a recruiter act on a candidate in the moment instead of waiting two weeks for a first conversation, and it means more candidates could reach the hiring manager with a much quicker turnaround time. Candidates rate the experience well, describing it as efficient, smart, and easy to do on their own time.

"Alex has interviewed more people in the past three weeks than this one recruiter could have possibly gotten to." For a leader who was openly skeptical, that has been enough to move her from cautious to recommending it to peers.

"I was skeptical in the beginning too. I'm very territorial over my hiring process and I'm proud of the work my recruiters do, so why fix it if it isn't broken? But you have to keep getting better and faster and more efficient, and this matched a need we had."

What's Next

The pilot expands next to a second region, giving Mattress Firm an East Coast and a West Coast footprint at once, with a company-wide store rollout planned to follow. From there, Candi expects to extend Alex to distribution center roles and, over time, to select high-applicant corporate openings where a single posting can draw hundreds of applicants in a weekend.

"I've already mentioned to my peers at Tempur Sealy and other companies that this is what we're doing, and this is really cool so far."
