I received an email from a recruiter, likely through Naukri. I sent my resume and received a call immediately.

First Round (Written):

Aptitude, Verbal, and Technical questions on Java/J2EE code snippets covering arrays and string concepts.

Questions I remember (1st round):

• What is a Java Package?
• Define wait, notify, notifyAll.
• Synchronization.
• try, catch, finally, throw, throws.

2nd Round:

This was conducted by a director. He will mostly gauge your attitude.

• Write a factorial program (be ready to write both iterative and recursive versions) and write test cases for it. Be prepared for some tricky questions.

3rd Round:

Java Concepts.

Concentrate on all the basic fundamental stuff. Be ready to write programs using them. Few of the concepts:

• String pool
• Overloading and overriding
• static
• Threads.

Be ready for a question about what your resume says. They usually ask a few DB queries.

4th Round:

• Write test cases for automation using Selenium.
• Write a program to divide a number into two halves and put them into an array; write test cases for it.
• Write a program to count the number of words in a file; write test cases for them.

5th Round:

Conducted by a senior person.

• One puzzle was asked (the 3-liter, 5-liter one).
• Write a program to find the depth of a binary tree.

To sum it up, an easy one.

6th Round:

Manager round.

DB questions:

• Write a query (an inner join with a pinch of salt).
• There is a database with redundant data (duplicate entries); how will you sort it out?

Java questions:

• Write a program and test cases to find the second biggest element in an array.
• Write a program and test cases to validate anagrams (e.g., GOD is an anagram of DOG).

It was a very long interview, but a good one.

7th Round (HR Round):

Just a formality.

Write test cases for a program counter (random number generator).
