위에서 열거한 여러 가지 인터뷰 질문들은 가장 기본적인 부분일 뿐이고, 이제는 좀 더 구체적으로 접근 방법을 통해 준비할 필요가 있는데, 두 가지의 경우를 생각해서 접근하시는 게 일반적이라고 할 수 있습니다.
구체적인 질문과 모범 답안을 통한 접근 방법
접근 방법 다음의 두 가지로 카테고리를 두고 그 안에서 준비해 나가면 훨씬 더 효과적일 수 있습니다. 카테고리별로 대표적인 몇 개의 예제 문항만을 추려서 소개합니다.
각 질문에 대해서는 가능한 답변을 1-3의 문장으로 구성해서 적었으니, 참조하시기 바랍니다.
1. Behavioral Question
- Can you describe a time when you had to make a difficult decision at work?
During a project, I identified a critical bug in our software close to the release date. I had to decide between pushing the release date or launching with the known issue. After discussing with the team, I chose to delay the release. It was tough, but it maintained our company's reputation for quality.
- What was the outcome? Tell me about a project where you had to work with a difficult team member. How did you handle the situation?
On a previous project, a team member consistently missed deadlines. I approached them privately, listened to their challenges, and together we found ways to streamline their workflow. By fostering open communication, the project was back on track.
- Describe a time when you failed in a project. What did you learn from that experience?
I once underestimated the complexity of a feature, which led to delays. From that experience, I learned the importance of early prototyping and regularly seeking feedback.
- Can you give an example of how you have handled stress and pressure at your previous job?
During a product launch, multiple critical issues arose. I took breaks to clear my mind, maintained a task list to stay organized, and ensured open communication with my team. This approach ensured we addressed all issues systematically.
- Tell me about an accomplishment that you are most proud of in your career so far.
I developed an optimization algorithm that reduced our application's processing time by 40%. It required extensive research and perseverance, but the impact on user experience made it worthwhile.
- How do you prioritize your tasks when given multiple assignments with the same deadline? Can you provide an example from your past experiences?
Once, I had three tasks with the same deadline. I prioritized based on project impact, complexity, and stakeholder urgency. For example, I tackled a bug fix for a high-profile client first, followed by tasks with lesser immediacy.
- Can you describe an instance where you took initiative without being asked to do so at work, and what was the result of it?
I noticed our team's workflow had redundant steps, so I researched and introduced a tool that streamlined our processes. This initiative led to a 20% increase in productivity.
- Tell me about a time when received criticism from your supervisor or coworker and how did respond to it or made changes based on it.
My supervisor once pointed out inefficiencies in my code. Instead of taking it personally, I took it as an opportunity to learn and improve. I attended workshops and revised my work, making it more efficient.
- Could describe an instance where demonstrated leadership skills even though were not in formal leadership position at that time?
Even though I wasn't a lead, when our team faced a challenging problem, I organized brainstorming sessions and delegated tasks based on each member's strengths. This collaborative approach led us to a solution more effectively.
- How have handled situation where had to adapt quickly changing circumstances or unexpected challenges at work? Describe situation where used data or analytical thinking solve problem.
During a project, a third-party service we depended on was deprecated. I quickly gathered the team, and we brainstormed alternative solutions, eventually integrating a new service with minimal disruption.
When users reported a decline in performance, I analyzed usage data to pinpoint the bottleneck. Based on the data, I recommended infrastructure changes, resolving the performance issue.
- Can you give me example of goal set for yourself at work and how went about achieving it?
I aimed to improve my coding efficiency. I set milestones, learned new techniques, and sought feedback. Within months, I reduced my average task completion time by 25%.
아래의 기술 면접은 특정 언어, 플랫폼에 제한을 두기보다는 일반적인 기술에 대해 포괄적으로 질문할 수 있는 사항을 열거했습니다. 이 외에도 회사, 팀, 그리고 수행하고 있는 프로젝트의 성격마다 다양하게 질문이 나올 수 있지만, 모든 문제를 다 대비할 수는 없지만, 자주 나오는 질문의 형식에 대해 미리 알고 준비를 하는 것과 그렇지 못하는 경우는 큰 차이가 있으니, 이 점 유의하셔서 준비하시면 됩니다.
2. Technical Question
- Can you explain the concept of OOP (Object-Oriented Programming) and its advantages?
OOP is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields, and code, in the form of procedures. Its main advantages include modularity, code reusability, and ease of maintenance and scalability.
- How do you manage version control in a large-scale project with multiple developers involved?
For large-scale projects with multiple developers, it's essential to use version control systems like Git. With Git, developers can create branches for features or bug fixes, ensuring that the main code (often the "master" or "main" branch) remains stable. Pull requests and code reviews help maintain code quality and resolve merge conflicts
- Could you describe your experience with cloud computing services like AWS, Google Cloud, or Microsoft Azure?
I've familiarized myself with major cloud platforms like AWS, Google Cloud, and Microsoft Azure. These platforms provide a suite of tools and services that aid in deploying, monitoring, and scaling applications. They offer solutions from virtual servers to machine learning capabilities, greatly enhancing application performance and scalability.
- What is your process for debugging code errors or issues in an application or system that you've developed? Can give me an example from your past experiences?
My debugging process involves first replicating the error, then breaking down the code to isolate the issue, using debuggers or print statements as necessary. For instance, once I encountered a memory leak issue, and by analyzing the code and monitoring memory usage patterns, I identified and fixed the culprit data structure.
- If we were to start migrating our systems onto microservices architecture, what would be some important considerations and steps involved in this process according to your experience or knowledge base?
When migrating to microservices, it's important to ensure services are loosely coupled, maintain a centralized configuration, implement proper service discovery, and ensure robust communication between services. Additionally, consider security, data consistency, and deployment strategies. Automated testing and continuous integration/delivery will aid in smoother transitions.
- Can you explain the difference between a statically typed language and a dynamically typed language, and give examples of each?
Statically typed languages require you to declare a variable's type at compile-time, ensuring type safety, e.g., Java, C++. Dynamically typed languages, like Python or JavaScript, determine the variable type at runtime, offering more flexibility but with potential runtime errors.
- How would you handle a situation where the codebase you're working on has no documentation or comments? What steps would you take to understand it better and make it more maintainable for future developers?
In the absence of documentation, I'd start by understanding the code's structure and flow, possibly mapping out its architecture. Next, I'd incrementally add comments and documentation, and engage in discussions with any available teammates who have worked on it. Automated tools can help generate basic documentation.
- Can you explain how RESTful APIs work and why they're important in web development today?
RESTful APIs are web services implementing the REST architecture, which stands for Representational State Transfer. They communicate using standard HTTP methods and status codes, URLs, and MIME types. Their stateless nature and use of standard conventions make them important in ensuring interoperability in web services today.
- Describe your understanding of SQL injection attacks and how they can be prevented when developing web applications. What are some best practices for ensuring that code is clean, efficient, and maintainable?
SQL injection attacks occur when unsanitized user input is directly passed to SQL queries, allowing malicious users to execute arbitrary SQL code. To prevent this, always use prepared statements or parameterized queries. For best coding practices, always follow the SOLID principles, write unit tests, and regularly refactor to maintain code health.
