• Would you answer a late-night text message from a recruiter after a job interview?
• The message is a test to help determine whether someone is a good fit for a job or a culture.
• William Vanderbloemen said that not texting back isn't a dealbreaker, but a fast reply is a plus.

You go to a job interview at 1 p.m.

At about 10 p.m., you get this text: "Hey, Tim. This is Ben. I work at Vanderbloemen. I was out of the office today. I heard you were there. Heard that everyone was really impressed with you. I'm sorry I didn't get to meet you. I would love to connect with you sometime. Hope that can work."

Do you reply? If so, how long does it take you?

Your decision might affect whether you're hired.

The test's creator and occasional proctor is William Vanderbloemen. He runs an executive search firm in Houston. Vanderbloemen's company uses the text-message test after job interviews for certain roles at his own hard-charging firm or for jobs where clients expect workers to be super responsive.

Texting back quickly might up your chance of snagging the job, at least at Vanderbloemen's 45-person firm.

Sounds simple enough. But the text is also a reminder of the always-on pressure that's pushed some workers to ditch hustle culture. Trial by text message joins other offbeat quizzes meant to help determine whether a job candidate should get an offer letter. There's the spouse interview over dinner. And there's the coffee-cup test: A hiring manager shows those who come for interviews where the kitchen is, offers them a coffee, and then rejects those who don't bus their dishes afterward.

The text-message test is also a reminder of how it can be difficult to land a job even as the overall US unemployment rate is low. Yet in areas like tech that have been slow to hire, some workers are left sending out huge numbers of résumés. And when job seekers do get a bite, interviews can drag on for round after round.

Vanderbloemen was quick to note that how you respond — or don't — to an after-hours text from someone saying they're with his firm won't keep you from getting a job. And he said that even responding within 24 hours would put most candidates far ahead of their competition.

"We're just terrible as humans at responding," he said.

But text back within the one-minute response time his sales and marketing teams operate by? "Then we're like, 'Yeah, no, he might be the same kind of crazy that we are,'" Vanderbloemen said. "Is that normal for every job? No. Would it work for every company? No."

The test came about after Vanderbloemen hired some people who seemed promising but then didn't deliver on the company's fast turnaround time for clients, which he said is essential for some roles. That led Vanderbloemen to determine he had to measure for speed — before making a hire — for jobs in areas like sales and marketing.

So, about a decade ago, Vanderbloemen asked one of the people on his team to text someone who'd been great in an interview. The colleague sent the text at about 10:30 p.m., and the candidate responded right away. Bingo.

Vanderbloemen, the founder and CEO of Vanderbloemen Search Group, decided the text-message test could be a good measure of whether a candidate would mesh well with a client with a move-fast culture. He compared it to pulling off a successful organ transplant by finding tissue that matches.

"Oh, you do things the way they do," he said. "Doesn't make it normal. Doesn't make it right. But you guys match each other."

Switching the interview location

Vanderbloemen doesn't rely just on the text-message test. One time, in New York City, he got turned around and realized he didn't have time to make it to the coffee shop where he'd planned to meet a job candidate. So he contacted the man and asked whether they could meet somewhere else. The man responded: "No, I don't mind. I like change."

Vanderbloemen was impressed. Now, he sometimes changes the location of an interview 30 minutes before it's scheduled to take place to see how a candidate responds.

He said it's not something he does all the time. Some jobs don't require that kind of flexibility or speed. Even with the text message, he said, it's often someone at his firm, not him, who might send it. As the boss, he realizes it's more intimidating if it comes from him.

"It's not fair because I'm the guy with the name on the door, and now I am being kind of just abusive," he said.

Setting up some rules

Vanderbloemen, who has a degree in religion and philosophy, said his company has guidelines meant to protect its workers from needing to be on at all hours. After-hours emails should get a response within 24 hours, he said. Evening Slack messages are rare though they should get a response that night "because that's like Defcon 3," he said. "Defcon 2 would be if I text you after hours, I need an answer like now," he added. "And if I call you after hours, pick up."

Vanderbloemen said the firm enforced the rules. It meant he and some colleagues had to quit a group text about "Game of Thrones" on Sunday nights.

He said he's received "some pretty negative feedback" about the text-message test.

"My answer to that is, 'Hey, I'm glad to know you feel that way. I don't think you'd be happy working here,'" Vanderbloemen said.

He said the test still has its place in a world where some workers are trying to avoid being on call all the time.

"For our company, particularly certain teams within our company, it's a direct indicator to us of whether you are dysfunctional like us," he quipped.

• "Business development" has become a coveted role at hedge funds amid the war to recruit top PMs.
• The Citadel BD ace Matthew Giannini's joining Walleye was one of the most noteworthy moves of 2024.
• Hedge funds hired dozens in BD in 2024 — BI tracked the names of more than 40 who joined top firms.

One of the most intriguing hedge-fund personnel moves in 2024 came late in the year. It wasn't a superstar portfolio manager or another big bank executive migrating to the buy side.

It was someone with barely any media profile at all: Matthew Giannini, a senior leader in Citadel's business-development unit whom Walleye Capital hired in October as chief operating officer of its long-short equities business.

The move from the industry's $66 billion killer whale to a much smaller fish surprised several industry insiders Business Insider spoke with at the time, underscoring the continued demand for the niche role of vetting and wooing investment professionals.

BI wrote in May about the evolution of the "business development" role, which has grown into a coveted specialty amid the boom in multimanager hedge funds. These firms, prized by investors for robust returns uncorrelated with the stock market, have added $200 billion in assets since 2019. Hiring has followed suit — head count since then soared by 90% at multimanagers compared with just 6% at other hedge funds — provoking a talent war that has been one of the industry's defining themes and challenges over the past few years.

Though total assets managed by these firms declined in 2024 for the first time in seven years (some investors pulled money amid growing costs paired with lackluster returns in 2023), "the war for talent appears to be continuing unabated," Goldman Sachs' prime-services team said in a September report on multimanager hedge funds. These roughly 50 firms added 2,400 employees over the previous year, Goldman found, a 15% increase.

Business development was no exception, with dozens of hires by top hedge funds in 2024, according to industry sources, LinkedIn bios, and publicly reported moves.

Millennium, the largest multimanager, with $72.1 billion in assets under management and more than 6,000 employees, hired at least 10 people in business development in 2024, BI found. Balyasny, which spent hundreds of millions of dollars hiring PMs this year, added at least six new BD executives to facilitate hiring, including three managing directors — most recently the commodities specialist David O'Connor, who joined in November from the external search firm Maven.

Citadel has been hiring as well, adding a handful of people to one of the most revered BD units in the industry. The hedge fund last year became the most profitable of all time, something its founder and CEO, Ken Griffin, attributed in part to an "unparalleled" ability to "recruit experienced professionals to Citadel" and "tremendous success attracting gifted graduates from the premier colleges and universities." Unsurprisingly, Griffin's talent whisperers are highly sought after.

Perhaps none has more gravitas than Giannini. Several industry professionals who know him say he's tall, charismatic, intelligent, and deft at winning over PMs — someone who provides an actual edge in an industry desperate for it. Giannini's leaving Balyasny in 2018 to rejoin Citadel contributed to a turf war between the funds.

"Matt is, if not the best, one of the best closers I've ever met," a BD professional told BI this year.

Leaving Citadel for Walleye may raise some eyebrows, but joining Walleye offers a potentially lucrative upside for Giannini compared with a typical BD role. Business group heads at these funds usually take home a cut of their unit's profits, and while Walleye struggled in 2023, it has been executing an overhaul that's bearing fruit. The fund was up by 15.4% through November, putting it near the top of its peer group for 2024.

He also joins some familiar faces at Walleye, including Thomas DeAngelis, an ex-Citadel BD leader who's now Walleye's president, and Anil Gondi, a longtime PM who joined from Balyasny this summer and will oversee the long-short equities division with Giannini. The two overlapped at Balyasny in the 2010s.

The hiring of Giannini and dozens of others at top funds in 2024 signals that the burning demand for investment talent, and those gifted in recruiting it, isn't likely to dim anytime soon.

"One clear theme from our conversations with multimanagers was that the 'war for talent' synonymous with this segment has not seen any material de-escalation in the last year," Goldman Sachs said in its report.
