Share my latest visit Microsoft The whole process of AI Engineer, pure practical information, personally tested the 2026 version. I applied for positions related to Azure AI/Copilot, focusing on LLM applications and MLOps. It took about 5 weeks from submission to getting the offer. The entire process values Azure ecology + generative AI practice + responsible AI more than SDE. Coding is not particularly abnormal, but the system design wheel is really heavy. It tests whether you can really implement the large model.
Microsoft AI Engineer interview process
- Submit your resume (official website or internal recommendation) and pass the initial screening by the AI system
- Recruiter phone screening (about 30 minutes)
- Complete OA (60-90 minutes)
- Technical (3 rounds, 45-60 minutes each)
- Final interview
- Receive interview result notification
Apply and Recruiter Screening
The first step is to submit your resume, either through Microsoft's official website or through internal referrals. The success rate of referrals will be much higher. An important point to note is that Microsoft uses an AI system to screen resumes. It is particularly important to have the right keywords, otherwise the resume will easily fall into the dust.
Resume preparation tips:
- Just keep your resume to 1-2 pages, the format should be simple and clear, don’t be fancy, just focus on the key points;
- Be sure to quantify the results. Don’t just say what you have done, but what effects you have achieved. For example, instead of just writing "Developing a RAG system", it is better to write "Using Azure OpenAI and Pinecone to build a RAG system, which reduced the model hallucination rate by 42% and increased user satisfaction by 35%". This will look more convincing;
- When talking about a project, it is recommended to use the STAR method, that is, first talk about the scene at the time and the tasks to be done, then talk about the actions you took, and finally talk about the results you achieved, focusing on how you chose the technology and how it affected the business.
Recruiter phone screening (about 30 minutes) FAQ:
- Tell us about your own background and projects you have worked on;
- Why do you want to apply for this position?
- How much do you know about Microsoft's AI products, such as Copilot and Azure AI?
Preparation points: In fact, this round is not difficult. It mainly depends on whether you communicate smoothly and whether you are in tune with the position. It is recommended that you learn more about Microsoft's AI ecosystem in advance, show some enthusiasm, and then prepare 2-3 projects that you are best at, as long as you can explain the ins and outs clearly.
Online Assessment
After passing the preliminary screening, you will soon receive an invitation to take the online written test, which is usually done on a platform such as Codility. Please pay attention to check your email.
Duration and question types:
It lasts 60-90 minutes in total, with 2-3 questions, including programming questions, AI/ML related tasks, and occasionally multiple-choice questions. The time must be allocated reasonably.
Main inspection contents:
- Generative AI related: For example, how to write Prompt so that it is easy to use, and the basic knowledge points of RAG;
- Basic knowledge of computer vision and NLP, no need to go too deep, but you need to know the core concepts;
- Responsible AI: For example, how to detect model bias, ensure fairness, and ensure security;
- Azure related services: You must have a basic understanding of Azure Machine Learning, Azure OpenAI Service, Cognitive Services, and Bot Service.
Microsoft AI Engineer technical aspects
Round 1: Coding
The first round is a typical algorithm question, the topic is LeetCode 56 (Merge Intervals).
The overall difficulty is not high, but it depends very much on basic skills. The core idea is to first sort the intervals according to the starting point, and then merge the overlapping intervals one by one. The real gap lies in the details, such as how to use lambda to write sorting in Python, and how to handle edge cases (such as empty arrays, single ranges, and completely non-overlapping situations).
This round of interviewers are more concerned about whether your code is concise, whether your logic is clear, and whether you take the initiative to explain your ideas while writing the code.
Round 2: Coding + Follow-up
In the second round, a layer of "thinking switching" inspection will be added to the basic algorithm. The title is LeetCode 235 (BST nearest common ancestor). If it is just BST, it is actually relatively straightforward. You can use the size rules of node values to quickly locate ancestor nodes.
Follow-up: What if BST is replaced by an ordinary binary tree?
At this time, you need to switch to the solution of LeetCode 236 and use recursion to find the common ancestor of the left and right subtrees. Many students tend to get stuck here because the idea needs to change from "utilizing structural characteristics" to "universal solutions".
Round 3: System Design
This round is basically the core of the entire interview. The topic is to design a "local sports recommendation system", but the actual test is your understanding of the implementation of the LLM system.
First we need to discuss architectural choices, such as whether to use RAG or Fine-tuning. Then we will delve into the model deployment level, such as how to reduce latency while ensuring effects. This usually involves optimization methods such as quantification and distillation.
Then we will definitely talk about a key issue: Hallucination (model hallucination). You need to explain how to reduce error messages, such as by introducing a retrieval mechanism, adding a verification layer, or even designing a mechanism similar to Red Teaming for output auditing.
After the whole round, what the interviewer is most concerned about is not whether you have a "standard answer", but whether you have complete AI system design capabilities, whether you can make reasonable trade-offs (such as effect vs cost, delay vs accuracy), and whether you really understand how LLM is implemented in real business.
Behavioral / Leadership Wheel
Frequently Asked Questions, Be Prepared in Advance:
- Tell me about a time when you failed or had a conflict with others and how you resolved it;
- What do you think of current LLM technology? You must see its value, but don’t blindly follow the trend. Tell us what you think about hype;
- Share a case where a project you worked on had a significant impact on users or business.
Answer suggestion: Just use the STAR structure and be clear and organized. Microsoft places special emphasis on Growth Mindset, Customer Obsession, and team collaboration capabilities. You can rely on these aspects when answering.
Stakeholder / Hiring Manager wheel
This round does not test specific technologies, but focuses more on the strategic level. We will talk to you about your understanding of Microsoft's AI direction and what value you can bring to the team. It mainly depends on whether you are in tune with the company culture and whether you have long-term development potential.
Are you worried about failing the AI interview at a major manufacturer?
I hope this interview experience can help you prepare effectively for the Microsoft AI Engineer interview. But to be honest, the difficulty of AI jobs in big factories now is: lack of time + too complicated preparations. Many students are stuck with incomplete resumes, unable to finish OA, and unable to explain VO clearly. In fact, it is not a problem of ability, but because there is no one to help you straighten the direction. If you need professional support in resume, OA, VO, etc., please feel free to contact our PROGRAMHELP team. We have helped thousands of students get on board, and their results can be checked!
