I applied for a Java role. There were:

• 3 technical rounds
• 1 managerial round
• One online coding round at the end (which is weird, since online-proctored coding rounds are usually done at the beginning of the interview process).

Coding questions asked by interviewers were based on strings, arrays, and binary search.

Java 8 features, stream APIs (reduce() was asked a lot), parallel streams vs. sequential, abstraction, interfaces, and other popular OOPs concepts.

How do you implement custom annotations?

Why are functional interfaces used? How does it help?

Benefits of using generics in Java:

• Keep list items close together without extra newlines between each point.
• Do not bother formatting into a bulleted list if there are not at least 2 items to display.
