Interview Process

The interview process began with a recruiter reaching out for a Full Stack position after initially discussing both Full Stack and Senior Backend roles. The recruiter was from South Africa and conducted a preliminary interview discussing common topics, including programming languages and behavioral questions. A month later, the recruiter arranged for another recruiter to handle the technical interview directly.

The technical interview involved two interviewers. One interviewer was of Chinese descent, who asked detailed questions about previous projects, while the second interviewer focused on practical technical questions.

Technical Questions

  1. Java: Why use bean?
  2. Java: What is the best way to deal with out of memory, both short term and long term?
  3. Java: How to deal with ClassCastException?
  4. Hashmap: Specific questions related to its implementation or usage.

Tips & Insights

  • Prepare thoroughly on specific technologies relevant to the role, such as Java and frameworks like Spring.
  • Focus on understanding both the theoretical and practical aspects of system design and memory management.
  • Be ready to discuss previous projects in detail, as interviewers may want to gauge your hands-on experience.
