Applied through campus recruitment. It was a one-day process.

There were four rounds:

1. Aptitude + Technical Online test
2. Coding
3. Technical Interview
4. HR Interview

The Aptitude round had 5 sections: passage (selecting the right words for fill in the blanks), Arithmetic Aptitude, Attention to Detail, C & Data Structures, Algorithms, and Java.

The passage section was tricky. Arithmetic Aptitude and Attention to Detail were easily doable. C & Data Structures, Algorithms, and Java were doable if you had practiced well.

I was exempted from the coding interview because I was among the top 6 in the first round. But I heard that the coding round was fairly easy.

So, 6 from the first round and 6 from the second round were shortlisted for the technical and HR interviews.

After clearing the technical interview, I was selected for HR along with one more guy. We both were given offers.

Technical (I am from a non-CS background, so I was asked a variety of questions):

1. Tell me about yourself.
2. Tell me about the projects you did.
3. Tell me about how you would approach a problem if you were working alone on a weekend and no one was there to help you.
4. Tell me the difference between Java and C.

HR (Easier and relaxed):
