Recently, I am applying for a backend developer summer internship and I have been asked a few questions were quite interesting. This post is a collection of backend interview questions which I have encountered. Hope it can help you when you are finding yourself in the same situation 🌟. Since I am applying positions based in China, I will discuss the questions both in Chinese and English.

最近，我正在寻找后端开发的暑期实习，被问了一些有趣的问题。这篇博客是我遇到的问题的汇总，希望能帮助到需要的人。因为我寻找的是大陆的岗位，所以在本文中会同时使用英文和中文。📚

Agent architecture is a software design for an intelligent agent. It is a concrete implementation of the abstract agent structure, which consists of perception, state, decision, and action. An agent architecture defines key data structures, operations on data structures, and control flow between operations. It is a crucial component of an AI system, as it directly influences the performance of the system. This post provides a comprehensive discussion of agent architecture in Lecture 5 of the SC4003 course in NTU.

Agent decision making is a crucial aspect of artificial intelligence. It is the process by which an autonomous entity, such as a robot or a computer program, makes decisions based on its available knowledge and perception of the environment. In this post, we will explore the different types of decision making, including simple and complex decisions, as well as sequential decision making, where the agent’s utility depends on a sequence of decisions. We will also discuss the various techniques used in decision making. This post provides a comprehensive discussion of the agent decision making in Lecture 4 of the SC4003 course in NTU.

In neural networks, there exist several free parameters: learning rate, batch size, number of layers, number of neurons, etc. We are faced with the problem of selecting the best model for a given regression or classification problem. There are various ways to do so. We can either select the best model with the best parameter value. This post is a lecture notes of the SC4001 course at NTU, covering model selection and overfitting.

In our team, March Studio, we developed a scheduling module that requires concurrency capabilities. Initially, we built this module using Python with the Flask library, but we encountered performance issues. As a result, we decided to create a simple web server using Golang. This module is still under development. This article documents my experience building a web server with Golang, and I hope it can be helpful to others.
