I applied through Instahyre and was called for a face-to-face discussion.

First round: Develop an event management system. Time allotted was 90 minutes.

Second round:

• Design a lift system.
• Implement the tail command of Unix in Java.
• Find the first occurrence of an element in a sorted array with duplicate elements.
• A few project-specific questions were asked.

Next round focused on coding:

• HashMap equals and hashCode.
• N meetings in 1 room problem.
• Garbage collection techniques in Java.
• Print even and odd numbers using threads.
• Which data structure is used to implement buckets in a HashMap?

I was told that I have average knowledge in Java, and they are looking for candidates with good knowledge.
