First-hand accounts from people who interviewed at LINE.
Procurement Manager
So first, I sent in my application online. Then came the first interview with a headhunter, the hiring manager, and one of the team members. They wanted me to give a 10-minute presentation beforehand, and after that, they asked me some questions about it. The next interview was a quick video call in English with the hiring manager and another manager from overseas. It was pretty intense, but they were nice and seemed to be checking how I thought strategically and if I could communicate well.
- What would you do to cover a lack of previous experience in indirect procurement?
Associate Manager, AI Projects
The hiring process involved an online assessment covering AI principles (10 questions), followed by another assessment on data analysis and labeling. After that, I had an online interview with more than five stakeholders. It felt very one-sided, with limited chances for real conversation. The interviewers focused more on personal stuff than professional accomplishments. I also got a vibe of some internal politics among the stakeholders, which could say something about the company culture. No feedback from HR after the interview, and they just ghosted me, which implied I wasn't moving forward. It was a very impersonal and transactional hiring experience, showing little respect for candidates.

Backend Engineer
So the interview process had a few steps. First, there was a coding test that took about 3 hours, and it included 3 LeetCode medium problems, an LRU cache question, and a system design question. Then, before the main interview, I had to do an online algo test within 30 minutes. The interview itself focused on reviewing that test and my background. After that, there was an online culture fit test. Finally, there was an HR call. I didn't pass the culture fit test.
- Can you explain the difference between multi-threading and multi-processing?
Web Developer
So first, a recruiter or HR person will call you to set up an initial phone screen. This chat is usually about your background, experience, and why you want to work here. It’s a good chance for you to ask about the company and for them to see if you’re a good fit. If that goes well, the next part is a technical interview, often over video. You might have to do some live coding while sharing your screen, and they could also ask you to design a system or architecture for a made-up situation. If you nail the technical part, you’ll then chat with the hiring manager. This interview is mostly behavioral questions, where they’ll ask about your past experiences, how you handle tough situations, and how you work with others. They might also dig a bit more into your technical skills and how they match what the team needs. Lastly, if you get through all of that, they’ll make a decision. If it’s a yes, you’ll get a job offer with all the details about the role, pay, benefits, and other stuff. You can then talk about it, ask questions, and decide if you want to accept.
- Could you implement a string reversal function in a language like Python, Java, or C++?
