How to ace an HFT interview in APAC’s competitive buy-side market
Cracking an interview at a high-frequency trading (HFT) firm or a hedge fund is one of the toughest challenges in finance. For mid-career developers, navigating these interviews takes more than strong coding skills. It calls for an understanding of the market, the strategies in demand, and the qualities firms prize most.
Professionals with four to seven years of experience are in demand from HFT firms. As the market continues to grow, knowing how to stand out in the interview process is essential.
Why APAC is hiring
The APAC region has become a growth engine for global trading firms. This is spurred by investment in colocation facilities and an increase in retail trading volumes in the region.
Asian hedge funds outperformed their peers globally, with 11.2% average returns in 2024. According to Grand View Research, the Asia Pacific HFT market expects to reach US$3,883.6 million by 2030.
As Frazer Ashman, Senior Recruiter at recruitment firm Tribus, explains, “demand is highest in Hong Kong, with Sydney a close second as a base for growth.” These cities are seeing strong demand as firms expand into markets across APAC and benefit from rising retail trading volumes.
Market trends
There is strong demand for quantitative developers and engineers who can build high-speed, low-latency trading systems. This is true across most proprietary trading teams and hedge funds operating across APAC.
Hiring is strong among buy-side firms, with several global firms expanding their presence in Hong Kong and Sydney. This is in contrast to the more conservative, replacement-driven hiring on the sell side (investment banks). As Frazer states, “what we see is candidates typically try to move from the sell side to the buy side to increase their pay packet.”
HFT is a technology-driven field, so a strong foundation in hard science is essential.
The HFT interview process
The HFT interview process is distinct from other finance roles. As Frazer explains, “there is a much higher reliance on core maths, as high-frequency trading firms are reliant on quantitative models and algorithmic code, which is, at its core, applied mathematics."
What to expect
HFT interviews are known for their intensity. Candidates should expect between five and ten rounds; the majority will be highly technical. These may include live coding challenges, algorithm-solving problems, and mental maths tests. Problem-solving questions test speed and accuracy. Behavioural interviews remain, but technical assessments dominate.
Technical preparation is non-negotiable. As Frazer states, “candidates need to pass the technical rounds." And there are plenty of ways to practise for such technical challenges. He advises "looking at algorithm-solving problems on GitHub or LeetCode. There are 30-minute tests of medium to hard difficulty.” He says, "If you can do those, it's almost replicated by how these interviews run." Participation in coding competitions can also hone the skills that are most relevant to HFT assessments.
The skills firms look for
The core components crucial for success in HFT are programming (computer science), maths (quantitative analysis), and trading experience. Candidates with backgrounds in mathematics, physics, or computer science are in high demand. Employers in this space are searching for deep specialists, not generalists.
“Candidates should have strong algorithmic coding skills. The core knowledge of low-level C++ comes up in every interview,” says Frazer. Familiarity with modern technologies and a proven track record of building performant systems are essential. Research and development experience also sets candidates apart.
Frazer says firms like to see evidence of candidates “having generated that idea on your own, rather than developing legacy ideas. The ability to think for yourself is a big one.”
He explains that PhD graduates do quite well, not because they hold a PhD, but because of the research and development qualities needed to complete a PhD.
Firms seek candidates with trading skills and an understanding of market dynamics. A trading track record is one way to impress hiring managers. The ability to articulate complex technical concepts is vital. This is essential for collaborating with other teams, including traders and researchers, and for explaining the reasoning behind a solution.
How to prepare
A common mistake candidates make is not knowing the role. Preparation begins long before the interview. Candidates should research the firm’s trading strategies, culture, and recent market activity. They need to explain why they want to work there. “Understanding the team you’re interviewing for is critical, as many candidates fail because they don’t fully grasp the role or company.”
Candidates are advised to practice coding challenges and algorithmic problem-solving using online platforms. Frazer recommends:
- LeetCode (set filters to medium/hard; focus on data structures used in HFT like queues, heaps, and trees)
- HackerRank (has system design and concurrency-related challenges)
- Codeforces (great for algorithmic speed and problem-solving under pressure)
Specialist recruitment
Specialist recruiters can offer insight into a company’s culture, the role, and the assessment process. Tribus applies this knowledge to guide candidates through the preparation and interview process.
The bigger picture
Hiring momentum in APAC is strong, but job competition is intense. Firms want candidates who can demonstrate technical brilliance and adapt to fast-moving trading environments.
For those who can prepare well and showcase the right mix of skills, the opportunities are vast. As the buy-side continues to invest in APAC, now is the time for professionals with the right background to step forward and take on the challenge.
