Core answer
Whether you have a 60-90s intro (Present/Past/Future) that's specific and ends on why this role.
A generic 'passionate about coding' intro, or rambling past 2 minutes with no structure.
60-90s: Present (who you are) -> Past (what you've built) -> Future (why this role). Be specific; end on why THIS role; practice out loud.

Interview answer
I recently completed my computer science degree, where I became most interested in backend development because I enjoy turning a requirement into clear data and application behaviour. Over the last year I have worked mainly with Ruby, Rails, PostgreSQL, Git, and automated tests rather than trying to list every technology I have touched.
My main project is a small appointment-booking API. I designed the Rails models and REST endpoints, added validation to prevent overlapping slots, and wrote request tests for successful bookings and conflicts. For example, the first version allowed two requests to reserve the same slot, so I added a database constraint and handled that failure as a conflict response instead of relying only on an application check.
That project taught me that a feature is more than the happy-path code. I had to think about migrations, error responses, test data, logs, and how another developer would run the application. I also used pull requests for my changes and kept the setup documented so the project was reproducible.
I am now looking for a junior backend role where I can contribute this foundation to a real product, learn from code review, and improve how I design and operate Rails services. This position is relevant to me because it combines the Ruby work I have practised with the team-based engineering experience I want to develop next.
Self Introduction
Direct Answer
A useful fresher introduction is a short, relevant story: your present role or education, the backend skills you can demonstrate, one project with a concrete contribution, and the reason this role is the next logical step. It should sound like a person explaining their direction, not a list of every course or a memorised slogan. Around one minute is usually enough, and every claim should open a follow-up you are prepared to answer.
Deep Dive & Architecture
An introduction is a relevance filter. The listener already has the resume; the spoken version should connect its strongest evidence into one direction. Present context explains where the candidate is now, a project proves applied ability, and the final connection explains why this role follows naturally.
Specific nouns make an introduction credible. “A Rails appointment API with PostgreSQL” gives a clearer picture than “several innovative projects.” One decision—preventing overlapping bookings, reducing a slow query, or designing an error response—shows ownership without turning the opening into a full project presentation.
Every detail creates a likely question. Mentioning Sidekiq means being ready to explain what ran in the job, how failure was handled, and why it was asynchronous. Removing a technology from the opening is better than planting a claim supported only by a tutorial.
The closing connection should be genuine and role-specific: backend product work, Rails maintenance, API development, or learning within an experienced team. Personal biography, marks, hobbies, and unrelated tools belong only when they explain a useful strength or the interviewer explicitly asks for them.
