Landing your first or second role as a junior developer can feel overwhelming, especially when the interview is in English. This simulated conversation walks you through every stage of a real-world tech interview — from introducing yourself and discussing your tech stack to handling tricky technical questions and asking smart questions back. Whether you are preparing for your next opportunity or brushing up on professional English, the vocabulary and strategies here will make a real difference.
How should you introduce yourself in a developer interview?
The interview opens with a classic prompt: "I want to know more about yourself." [0:18] A strong answer follows a clear timeline. The candidate explains a career switch from biology to software development, mentioning online courses, personal projects, and landing a first job as a junior developer. Notice the natural way to handle nerves: "Pardon, I'm a bit nervous, I'm sorry" [1:07]. The interviewer responds warmly — "Don't worry" — which is common in supportive work environments.
Key vocabulary to remember:
- Resume: the document summarizing your experience and skills.
- Junior developer: an entry-level engineering role.
- Front-end: the user-facing side of an application.
- Full stack: working on both front-end and back-end.
When asked "With which technologies have you worked?" [1:18], the candidate mentions React, AWS deployments, Ruby on Rails, and PostgreSQL databases. Being specific about your tech stack shows you understand what you have actually used in production.
Why did you switch jobs?
This question tests self-awareness. The candidate explains the first role was "a bit limiting" [2:05] because it focused only on front-end work. Wanting to become more full stack is a positive and honest reason. Mentioning that a friend referred them to the next company highlights the importance of networking in tech careers.
Why do you want to work here?
At [2:47], the interviewer asks this essential question. The candidate references the company's mission, values, and culture — specifically honesty and being "good at failures." Showing you have researched the company demonstrates genuine interest and preparation.
How should you handle tricky technical questions?
The interviewer asks a very specific question about Active Record and default scopes [3:28]. This is deliberately described as a trick question — the kind that tests memorization rather than real problem-solving ability.
Two possible responses are modeled:
- Confident and firm: "I would just Google it. The documentation is what I use all the time." If the company insists on memorization, you can politely decline: "If this is the kind of company you are, I might not be interested." [4:01]
- Calm and practical: acknowledge you would look it up, referencing online documentation.
The key lesson here is that modern companies no longer rely on whiteboard algorithm tests or obscure method-name quizzes [3:40]. Instead, they ask behavioral and project-based questions. Pay attention to the style of questions — they reveal the company culture.
What has been your most challenging project?
At [4:44], the interviewer shifts to a behavioral question. The candidate describes building a hardware radio system to communicate with a satellite, including custom antennas and a website showing the satellite's orbit. What stands out is the passion and excitement in the answer, plus evidence of teamwork — collaborating in a chat group, helping each other solve connection problems [5:24].
The interviewer explicitly praises both the enthusiasm and the collaborative approach, reinforcing that teamwork matters.
What questions should you ask the interviewer?
Asking thoughtful questions shows engagement. The candidate asks about three important topics [6:15]:
- Team structure: the company uses an agile process with two-week sprints, daily stand-ups, four to five engineers, one engineering manager, and one product manager.
- Conferences and events: the company encourages attending and even speaking at conferences for professional growth and networking.
- Support for junior developers: the company offers a buddy system during onboarding and a mentoring program [6:55].
These questions reveal what the candidate values: growth, learning from others, and becoming a better software engineer.
The interview ends with clear next steps [7:24] — a take-home project building a website "like an Instagram but for pets," followed by a code review with engineers the following week. The answer to the trick question, by the way, was unscoped [8:05].
