I appeared for a walk-in interview for a role requiring 4 years of experience.

The process is as follows:

• You will first receive a call from HR regarding the job description.
• If you are shortlisted, you will then receive a confirmation email.

The interview process includes two rounds, both of which are technical.

Basic Questions Asked:

• Introduce yourself (including questions about your current project).
• Why is String immutable in Java, and how can we create an immutable class?
• Streams coding question – Given a list of integers, find all numbers starting with 1.
• Explain Predicate and BiFunction interfaces.
• Explain/implement the Bubble Sort algorithm.
• Explain Future in Java.
• Difference between fail-fast and fail-safe iterators.
• Java 8 features.
