I applied online. The process took 2 months. I interviewed at Airwallex (Amsterdam) in May 2021
Interview
First of all, it was a very tiring process. I interviewed for around 2 months and I did an assignment + 3 revisions + 4 technical interviews. It was very unclear what they wanted. First, they said they want a DevOps engineer, then they said I can start as a Developer because in their opinion I am a better fit to the dev team. Then they said that I don’t have knowledge on IaaS or GitOps out of blue which was never mentioned before. I did a Java assignment which was unrelated to the things they asked. I would really suggest them to clear their requirements before interviewing candidates and wasting their time. Also, in the second before last interview, one of the founders named Qiao joined and never spoke with me at all and then left which was very rude and he didn’t apologize at all.
Overall, it was a pretty negative experience for me and good luck with their unclear search.
PS: Their CTO’s English was very difficult to understand with a pretty bad accent and it is like a boss company where they only listen what bosses say, nothing else.

Question 1
- A project about building an RPN Calculator with Java.
- Standard Java questions.
- Random IaaS and GitOps questions that are unrelated to the position.
First Interviewer cancelled on me twice. Third time was the charm.
Interviewed me for 20 minutes despite it being a senior role. Did not ask me a thing about my experience at all. Just gave a leetcode-style simulation question which was quite easy. Did not ask follow-ups even though we had time left and I deliberately took pains to keep my code flexible and extendable. Asked me to email him my (correct) answer and hung up within 25 minutes tops. Received rejection on the grounds that "other candidates were better".
Got shunted into a different role by the recruiter. Interviewer again cancelled twice - once on the morning of, and once AFTER I was already in the Zoom and waiting.
Voluntarily dropped out at that point
I applied through a recruiter. I interviewed at Airwallex (Singapore) in Dec 2025
Interview
Overall it was a smooth interview process, The HR response time is fairly quick when providing interview results and scheduling the subsequent ones. Interviewers I have met are friendly and competent, although seems to be team dependent.
