“Senior из Amazon Олег Кожанов о том, что должен знать разработчик на разных этапах карьеры”

This video is an in-depth interview and discussion with Oleg Kozhanov, a senior developer currently working at Amazon. The conversation focuses on the knowledge, skills, and mindset a software developer should have at various stages of their career—from intern to senior roles—and provides insights into the hiring and professional development process.

Key Technological Concepts and Career Insights

1. Career Path and Early Experience

Oleg started programming driven by an early passion for computer games.
He studied at Moscow State Technical University (Bauman Moscow State Technical University).
Early jobs involved working on internal tools automating translation processes (scripts automating tasks in software translation).
His first real development experience was in a startup environment, growing with the product and team over 10 years.
Networking and university connections played a crucial role in landing his first developer job.

2. Stages of Developer Growth

Intern: Focus on learning tools and instrumentation, following clear instructions on what, how, and when to do tasks. Interns are not expected to make independent decisions.
Junior Developer: Expected to start showing independence in problem-solving but still works within clear boundaries and guidance.
Middle Developer: Gains responsibility, estimates task completion times, understands productivity, and begins to add value beyond assigned tasks. Starts developing independence and accountability.
Senior Developer (Synergist): Manages others, delegates tasks responsibly, defines architecture, writes technical specifications, and acts as a force multiplier by transferring knowledge and increasing team productivity.

3. Interview and Hiring Process

Early interviews often focus on personality and potential rather than deep technical skills.
Networking helps bypass initial cold application stages and recruiter screenings.
Interview questions for developers often focus on language-specific knowledge (e.g., C# methods to check if an object is empty), SQL, and problem-solving skills.
A good interviewer aims to help candidates show their best qualities rather than to fail them.
Feedback from interviews is often limited; candidates are advised to analyze rejection patterns themselves and not overly dwell on negative experiences.

4. Technical Skills and Knowledge

Algorithms and Data Structures: Essential foundational knowledge for developers, especially important for system-level programming (e.g., DBMS kernel development). However, many developers in enterprise environments rely on libraries and frameworks.
Breadth vs. Depth: Oleg emphasizes the importance of having a broad skill set rather than focusing too narrowly on one technology. He warns against over-specialization that limits adaptability.
Programming Languages: While juniors should focus on mastering the tools used at their workplace, expanding knowledge to other languages (Python, Java, Go, C#) is beneficial over time.
Asynchronous Programming: Recommended knowledge for juniors and above to understand different problem-solving approaches.
Software Tools: Interns need basic tools to learn and grow; as developers progress, they add more sophisticated tools depending on their roles and company culture.

5. Culture and Professional Development

Healthy team culture is based on professionalism, hard and soft skills, and productive collaboration—not on personal friendships or social drinking habits.
Developers should cultivate responsibility, purposefulness, and curiosity to grow.
Promotion processes differ between Russia and Western companies, with Western firms often promoting based on demonstrated performance while Russian companies sometimes promote prematurely.

6. Learning New Technologies

Oleg recommends practical learning by re-implementing existing projects using new technologies to evaluate their suitability.
Starting with small projects (“Hello World”) and expanding to production-level tasks is a good approach.
Understanding architecture is key before diving into implementation—either top-down decomposition or bottom-up composition methods can be used.

7. Miscellaneous

The discussion touched on the impact of freelancing and outsourcing on the job market.
Oleg shared personal anecdotes about his work experience, interview stories, and the evolution of his responsibilities.
The importance of reading code and understanding projects is highlighted as a valuable learning method beyond books.
Recommended reading includes Jeffrey Richter’s books on C#, and Python books like Python 3 and 10 and Lutz (likely referring to Mark Lutz’s Python books).
The interview also briefly discussed differences in labor protections and corporate culture between Russia and Western countries.

Product Features, Reviews, Guides, Tutorials Mentioned

Interview Preparation: Focus on language-specific details, algorithms, and problem-solving. Emphasis on demonstrating responsibility and learning ability. Advice on how to interpret rejection and seek feedback.
Learning Path: Practical project-based learning. Gradual increase in independence and responsibility. Balancing depth and breadth in technology skills.
Recommended Books:
- Jeffrey Richter’s books on C# internals
- Mark Lutz’s Python books
- Python asynchronous programming resources
Networking and Job Search Tips: Use connections to bypass cold application stages. Importance of soft skills and cultural fit. Avoid relying solely on formal interviews; build relationships.
