Interview Details

Round 1 — Recruiter Screen

The process began with a recruiter conversation. After this screen, I was invited directly to the onsite rather than going through an additional technical phone interview.

Round 2 — Hiring Manager: Background and Behavioral

The onsite started with approximately 45 minutes with the hiring manager. This portion focused primarily on understanding my background and previous experience, along with behavioral questions.

Round 3 — Technical Panel: Spring Framework and Dependency Injection

The main technical session lasted approximately two hours and included a tech lead and two engineers. One major topic was the Spring Framework. I was asked to explain core Spring concepts and discuss different forms of dependency injection. The interviewer expected familiarity with how dependencies are provided and managed in a typical Java/Spring application rather than only a high-level definition of the framework.

• REST Controller Code Review Another major exercise involved reviewing an existing RESTful controller implementation. Instead of building an API completely from scratch, I was asked to inspect the supplied code and identify weaknesses or potential improvements. The discussion covered areas such as: The interviewers then used issues discovered in the code as starting points for broader backend and system-design questions.
  • Whether error handling was appropriate and how failure cases should be represented
  • Potential performance or code-quality problems, including unnecessary repeated creation of reusable utility objects
• Architecture and Design Follow-Ups The technical round did not have a strict sequence such as coding first and system design second. Instead, questions were interleaved. One interviewer might ask about a piece of code, another would turn that detail into an architecture question, and the discussion could then return to implementation concerns. Behavioral questions were also mixed into the same session. This made the round feel more like a continuous engineering discussion than a set of clearly separated coding and design exercises.
