Airtel Payments Bank Account Executive interview: logistical whiplash after Noida
My process started with an in-person first round at the Noida office. HR then went quiet for about two weeks, leaving me unsure what was happening. When the same contact returned, they tried to set up a same-day HRBP round. I already had another interview in Gurgaon, and they proposed that I finish it and come straight to their Gurgaon office. It felt like a circus, more logistical whiplash than…

Airtel Payments Bank Software Engineer interview with cab-booking database design
After a recruiter call, I had an assessment and then a couple of deeper conversations. The first round checked coding and fundamentals. I worked through cab-booking-style queries, including how to normalize a database and what indexes to add on relevant columns. Java collections also came up, along with a linked-list DSA challenge. The technical discussion felt more like a guided deep dive than a…

Airwallex Data Scientist Interview Experience — SQL Metrics and a KYC Conversion Case
I recently interviewed for a Data Scientist role at Airwallex and wanted to contribute my interview experience. Overall, it was SQL plus a case study. The questions themselves were not especially hard, but the pace was fairly fast, and the case placed more weight on product sense and analytical thinking. First part: SQL They gave me three tables, roughly sessions, signup, and merchant. I remember…

Airwallex Pty Software Engineer Interview Experience: CTO database-modeling pivot after positive signals
I went through an intense sequence that ended in a final-round rejection. After a recruiter call, I had live coding, a system-design round, and behavioral questions. The difficulty felt average until then. The final CTO round was what threw me off. He repeated questions that had already been covered in a behavioral conversation with a senior director, then concluded that I was not a good fit. He…

Airwallex Pty Software Engineer interview experience: unclear role fit and rejection
The recruiter stage is what I remember most, and it set a poor tone. After the HR conversation, there was back-and-forth about the roles and where my background might fit, but I never got a clear picture of what I was actually being considered for. Instead of entering a full interview loop, I received a rejection email saying I was not selected for either role we had discussed. Another experience…

Airwallex Senior Data Scientist Interview Experience — Passed Two Case Rounds, Lost at the HM Round
The whole loop was 5 rounds, and each round felt like beating a boss to level up. Round 1: SQL + case The SQL part was basically very similar to another post I've seen on the forum — there were some variations on the questions, but the topics were the same. After the SQL, there was a case. They gave me a credit card approval rate time series from Jan 2013 to Jan 2015. There was a dip in Feb 2013,…

Airwallex Software Engineer Interview Experience — A Sunday Night System Design Screen Where the Interviewer Just Went Silent
This is an Australian payments company. Their dev team is mainly based in Singapore. When HR reached out, they picked a really late time slot to schedule things. Then for the phone screen, they booked me in for the system design round on Sunday night at 9pm. HR told me they use Whimsical for the whiteboard. But then it turned out the interviewer's team doesn't actually have a fixed whiteboard too…

Airwallex Software Engineer Interview Experience: CTO rejection after full loop
I completed the full Software Engineer loop, which ended with the CTO. After the recruiter conversation, I had live coding, system design, and behavioral rounds. They were standard and aligned with the role. The CTO round did not feel like a fresh evaluation. He repeated many of the questions that had come up earlier with a senior director in the behavioral discussion. Along with lower-level tech…

Airwallex Software Engineer Interview Experience: HR discussed a second role before rejecting both
My process with Airwallex was straightforward until the HR call. The HR interviewer asked about my background and said that, based on what I shared, another role might suit the team better. We discussed that opportunity and went back and forth enough that it felt as though things were moving. Then it ended quickly. I received a rejection email saying I was not selected for either role we had disc…

Airwallex Software Engineer Interview Experience — Real-Time Robot-Chase System Design, Then a Rejection with No Feedback
It was a direct two-round company screen — coding plus system design — and if you pass, the next step is the hiring manager round. The interviewer was based in China, so we could only schedule evening slots. The team is a new one in Seattle building a productivity tool. System Design — a real-time robot-chase mini-game The problem: the player moves around on a 500×500 terrain grid, and different-…

Airwallex Staff Data Scientist Interview Experience — Five Rounds, Rejected After the HM Round
The whole loop was five rounds, and every round felt like leveling up to fight a bigger boss. Round 1: SQL + case The SQL was basically similar to a post I'd seen before — there were some variations in the questions, but the type of question was the same. After the SQL there was a case. The case gives you a credit card approval rate time series from Jan 2013 to Jan 2015. There's a dip in Feb 2013…

Akamai Software Engineer interview
I applied through the website and heard from HR. They arranged a Zoom-style interview, and I later met with the hiring manager. After that hiring-manager interview, the process went quiet. I followed up but never heard back. The early steps seemed standard, yet there was no closure afterward. If the decision was a rejection, I would have preferred a clear response. Location: Tel Aviv-Yafo. Overal…

AKUNA CAPITAL Quantitative Analyst Interview Experience: Canditech completed but HackerRank access missing
After a recruiter-style step, I was routed into a tightly scheduled online assessment sequence. One Canditech portion was harder and had multiple questions where I was expected to explain my thinking and math as I went. The other portion was supposed to be a HackerRank test immediately afterward, but I never received access despite reaching out multiple times. I did complete Canditech. It had sev…

AKUNA CAPITAL Quantitative Analyst interview experience: math video and coding screen
My run began with an online assessment and video interview, then moved into a more interactive technical round. During the video step, I answered math and probability questions and had to explain how I reached each solution. It was not enough to give an answer. I needed to make my reasoning clear. The technical round included coding-related questions and a couple that connected to my resume. The…

AKUNA CAPITAL Quantitative Analyst interview with options lectures and probability questions
Before any live interviews, I went through a mini-lecture series covering trading and options basics. There were three lectures, each paired with an online quiz that I had to complete before moving on. The process felt selective because only the top performers on those quizzes were chosen for the interview round, although they never explained exactly how the "top" threshold was determined. I then…

AKUNA CAPITAL Quantitative Analyst interview with quant-style math testing
My process started with the usual screening and assessments, then moved into online testing that leaned heavily on quant style math. I reached the later stages, including a final technical evaluation. The last question was the one that tripped me up. I couldn't land the final step cleanly, and I couldn't tell whether that meant I was done entirely or whether there was any behavioral wrap-up after…

AKUNA CAPITAL Quantitative Analyst interview with two hour-long probability rounds
I went through an assessment-heavy process in which the later rounds shifted from coding toward deeper probability. After passing the earlier online steps, I reached a technical screen focused on probability and statistics. It was genuinely hard and reminded me of the tougher Greenbook-style questions people mention for quant research. As I progressed, the final interviews focused almost entirely…

AKUNA CAPITAL Quantitative Analyst: Probability, Math, and In-Office Final Round
I went through a multi-round process that ended with an in-office final step. Before that, the early stages felt like a series of online hurdles that filtered people quickly. Once I reached the last round, the environment felt supportive. Everyone I met in person was nice and made it easier to focus. Probability and math came up repeatedly on the technical side. In the later stages, I was asked m…

AKUNA CAPITAL Software Engineer HackerRank OA and live coding screen
After applying, I was immediately routed into a HackerRank OA that I had to complete in about an hour. Once I finished it, I received an invitation to a first-round technical discussion. It took place over Zoom, and before the call I was sent a coding link where I would write the solution. The flow was fairly standard: an OA followed by a real-time coding screen focused on how I approached the pr…

AKUNA CAPITAL Software Engineer HackerRank OA, coding rounds, and final day
I went through an OA and then a series of technical rounds that ended with a demanding final day. The initial HackerRank assessment was followed by an exchange-engine-style coding focus in a later interview, where I had to implement a simplified version and explain what I was doing as I went. By the final stage, the interviews were intense and back-to-back. There were four in a row, including tec…

Akuna Capital Software Engineer Interview Experience — Hexadecimal AND and Binary Tree Recursion
This technical interview mainly covered C++ fundamentals, bitwise operations, binary-tree recursion, and dynamic memory management. The questions themselves were not difficult, but there was a strong focus on pointer use, boundary conditions, and low-level implementation details. Bitwise Operation Question: Calculate: Convert both hexadecimal values to binary: After applying the bitwise AND: Ther…

AKUNA CAPITAL Software Engineer interview, HackerRank OA
My process started with a HackerRank OA focused on implementing business requirements rather than practicing classic algorithms. My version had two questions. One focused on strings and felt fairly direct. The other relied more on object-oriented concepts, which I found harder because I hadn’t practiced that style enough. Even though the difficulty was described as not necessarily algorithmically…

AKUNA CAPITAL Software Engineer interview with four C++ technical rounds
My process started with a HackerRank online assessment and quickly moved into several technical interviews. The first programming question didn’t feel like a typical LeetCode problem. It was more like a medium-level simulation, and it pushed me to think about how the system behaved instead of simply deriving a clean algorithm. After the assessment, I went through four technical interview rounds.…

AkunaCapital Quantitative Analyst Interview Experience: a missing HackerRank link stalled two assessments
After a recruiter step, I was given an online assessment split into two back-to-back parts: a HackerRank coding test and a Canditech portion. The plan was one harder LeetCode-style HackerRank problem, then Canditech questions where I would explain my thinking through math and probability prompts. Canditech also included mental math and a recorded video response within a time limit. I never comple…
