🧪 9-BO‘LIM: Post asosidagi savollar va javoblar (Node.js backend uchun, ammo Python dev uchun moslashtirilgan)

🔸 1. Self-Introduction (Pitch) – Ingliz tilida qisqacha nutq

Savol: Tell me about yourself.

✅ Sample Answer:

I’m a backend engineer with 4+ years of experience in Python, Django, and FastAPI. I’ve mainly worked on high-load systems in the education, agriculture, and payments domains. I’m proficient in building REST APIs, integrating CI/CD pipelines, containerizing services with Docker, and optimizing SQL/NoSQL databases. I’ve also worked in Agile teams with a strong focus on code quality, testing, and performance. Currently, I’m focusing on scalable microservice architecture and real-time analytics with tools like Kafka and Redis.

🔸 2. Agile & Scrum savollar

Savol: Agile nima? Scrum jarayonida qanday qatnashgansiz?

✅ Javob:

Agile is an iterative approach to software delivery. Scrum is one of its implementations with fixed-length sprints, daily standups, sprint planning, and retrospectives. In my teams, I participated in story point estimations, delivered features every sprint, and regularly discussed blockers and improvements in retros.

🔸 3. Git & Gitflow

Savol: Gitflow nima? Branchlar bilan qanday ishlaysiz?

✅ Javob:

Gitflow is a branching strategy with long-lived branches like main and develop, and short-lived branches like feature/, hotfix/, and release/. I usually work with feature/ branches, submit PRs for code review, and use rebase for clean history.

🔸 4. Code Review

Savol: Siz loyihada CodeReview qilganmisiz? Nima qilasiz review paytida?

✅ Javob:

Yes, I’ve participated in code reviews regularly. I check for:

• Code readability
• Reusability
• Adherence to project conventions
• Security vulnerabilities
• Test coverage I leave constructive comments and often suggest better naming or logic simplifications.

🔸 5. CI/CD tushunchasi

Savol: CI/CD nima? Siz qayerda ishlatgansiz?

✅ Javob:

CI is Continuous Integration – tests and builds are run on every push. CD is Continuous Delivery or Deployment – new versions are automatically deployed to staging or production. I’ve used GitHub Actions and GitLab CI to automate testing, Docker image building, and deployment to EC2 and Kubernetes.

🔸 6. Docker asoslari

Savol: Docker haqida nima bilasiz?

✅ Javob:

Docker allows us to package applications in containers, including all dependencies. I’ve used it to:

• Build Docker images from Dockerfiles
• Use docker-compose for multi-container setup (web + db + redis)
• Mount volumes for persistent data
• Debug container behavior with logs and exec commands

🔸 7. REST API tushunchasi

Savol: REST API nima? U bilan qanday ishlagansiz?

✅ Javob:

REST is a stateless API architecture that uses standard HTTP methods. In Django REST Framework and FastAPI, I’ve built endpoints using serializers, routers, and response models. I followed REST conventions like:

• GET /users/
• POST /users/
• PUT /users/{id}/
• DELETE /users/{id}/

🔸 8. Event Loop, Stream, Error Handling (Node.jsga mos, lekin analogi)

Savol: Python’dagi async qanday ishlaydi? Node.js’ga o‘xshashmisiz?

✅ Javob:

Yes, Python has async/await, which is similar to Node.js’s event loop model. Using asyncio, FastAPI, and aiohttp, I’ve handled thousands of concurrent requests efficiently without blocking. Streams analogi – generatorlar (yield), or async iterators.

🔸 9. Error handling: DRY & graceful degradation

Savol: Katta tizimda error handlingni qanday qilasiz?

✅ Javob:

I use a centralized exception handler. In Django/DRF I override ExceptionHandler, in FastAPI I use @app.exception_handler. I log detailed errors using Sentry and show users safe, helpful messages.

🔸 10. Indexlar va SQL vs NoSQL

Savol: Qachon SQL, qachon NoSQL ishlatish kerak?

✅ Javob:

SQL – relational, structured data, need for complex queries, ACID – use PostgreSQL/MySQL. NoSQL – dynamic schema, scalability, high read/write throughput – use MongoDB, DynamoDB. Indexlar – searchni tezlashtiradi, lekin yozishdagi performance’ga ta’sir qilishi mumkin.

🔸 11. Caching, Logging, Monitoring (Grafana, Sentry)

Savol: Tizimni qanday observability bilan nazorat qilgansiz?

✅ Javob:

I use:

• Redis for caching common queries
• Sentry for real-time error tracking
• Grafana + Prometheus for metrics (CPU, memory, DB queries)
• Structured logging (JSON format) for easier debugging in production

🔸 12. OWASP Top 10 xavfsizlik xatoliklari

Savol: Qaysi xavfsizlik xatolarni oldini olganmisiz?

✅ Javob:

Ha, OWASP Top 10 asosida men quyidagilarga e’tibor berganman:

• SQL Injection → parametrized queries
• CSRF/XSS → Django’ning default himoyasi
• Broken Auth → JWT tokenlar bilan ishlash
• Sensitive Data Exposure → HTTPS, env-based config

🔸 13. Manager Interview uchun tayyorlik

Savol: Manager sizdan: “Nima proektga ishlashni istamaysiz?” deb so‘rasa?

✅ Javob:

I prefer not to work on gambling or surveillance-related projects. I enjoy contributing to EdTech, FinTech, or public good systems.
