HackerRank test is there... easy... questions from DP.

First round:

• Basic Java questions
• Data structures
• DP

Second round:

• Asked very basic Java questions.

I answered all questions properly. Finally, he said, "You can leave for the day. HR will come back to you." Then I asked, "Which questions did I get wrong?" He just told me, "You are good, but you have to explore more technology." If you guys know I am a Java developer, then why did you ask me to come for an interview if you need some other technology expert?????

I will suggest: If you have a job in hand, then don't go here to waste time.

First Round:

• Basics of Java: inheritance, collections, custom ArrayList, etc.
• Find the n-th highest number from a given array (which can hold duplicate values and be unsorted), etc.
• Implement a Doubly Linked List using stacks.
