I'm helping create this course and work as a server developer at Kakao. Actually, I wanted to hide the fact that I'm an interviewer... 😭😭 But I thought this would be such a great topic to cover, so I decided to join this course. As I mentioned, when I actually conduct interviews at Kakao, I'm not particularly curious about things from a programming perspective. Most of my questions focus on whether someone can do architectural design, and I consider `what kind of concepts this person can come up with` to be extremely important. Various problems can arise from this perspective, and one of those factors is distributed transactions. That's why I think this course is all the more beneficial. If you can answer these kinds of questions after taking this course, I think you'll have learned something truly meaningful. 1. Please tell me about the two patterns of SAGA (Choreography VS Orchestration) 2. Please tell me about the differences and pros/cons of these two patterns. I'm particularly curious about throughput and the problems that come with it. 3. Do you know the concept of local transactions?? (If you don't know, I'll explain it) Then how can distributed transactions be managed in relation to these transactions?? 4. Please tell me everything you know about distributed transactions in general. I'm curious. 5. Do you know what the Database per Service perspective is?? These are examples of questions I actually ask when I go into interviews. If you know about these areas and can answer them, it would be a great help. Please show a lot of interest in the course. Thank you!
