I applied through a staffing agency. The process took 4 weeks. I interviewed at OKG (Singapore) in June 2022
Interview
First off, this is one of the worst interviews I have ever experienced.
Without further ado, here are the top 10 things that went horribly wrong.
1. Interviewer took almost a month to get back to my application.
2. Interviewer was late for the actual interview.
3. I was informed that this would be a simple meet and greet. It turned out to be a full live coding and system design assessment.
4. You would think the interviewer prepared online coding interview tools beforehand. Something like coderpad. But no. I had to screen-share my own IDE and compile the results to show him.
5. For a localised role, the interviewer could hardly string together a proper sentence in English. The entire session was just me using Google Translate to articulate technical terms in Mandarin.
6. The interviewer was extremely impatient and kept interjecting my train of thought with his opinions. Please give your interviewees time to think instead of rushing to start coding.
7. The interviewer kept insisting on his own solution. My solution was actually more efficient but he wasn't happy when I challenged his.
8. The interviewer questioned my choice of programming language and wanted me to use his preferred one. Instant red flag.
9. The system design assessment seems more like a "guess what was his approach" assessment.
10. The final straw was when he abruptly hanged up my call.

Question 1
1. Leetcode - Buildings With an Ocean View
2. System design for e-payment system.
practical and hand on. 3 tech rounds. live coding involved but not heavily focused. experience demonstration is more important. interviewers are friendly and helpful. however the whole process can be very lengthy
I applied online. I interviewed at OKG (Hong Kong) in Feb 2026
Interview
The interview process was good, Li spoke well and was friendly.
Tested knowledge on Rust by asking questions about concepts and features generics, enums, clone/copy etc
Asked about work experience and specifically how I approached certain problems and how they were fixed.
The coding part was looking at some code and answering questions. Then onto a codepad website to solve a sliding window solution.
Overall; good interview, relaxed and friendly.

Question 1
Explain the difference between Generics vs Trait Objects
I had a disappointing interview experience. The interviewer appeared to have limited proficiency in English, despite the fact that English is one of the major languages spoken in the city where the interview took place. This created significant communication barriers. Whenever I used technical terms (for example, API), I first had to check if the interviewer was familiar with them. Most of the time, the answer was no, which forced me to spend several minutes explaining basic concepts in another language. As a result, what should have been a one-hour technical interview turned into repeated explanations of fundamental programming concepts, leaving little time for meaningful discussion of my skills or experience. The interview difficulty mainly come from the language barrier

Question 1
Can you explain some concepts that you usually wouldn't face in day to day operation in your previous internship experience?
