Tips for Aptitude round:
First of all, check the PC allocated to you, check the internet connection and the calculator in it
Be thorough with the fundamentals of Java and Python. These are the sections that save you time and gain maximum marks
SQL was the easiest part. You can eliminate a few options if you have a basic knowledge of SQL syntax
Aptitude was the lengthiest part. Try saving extra time(preferably 45 minutes or more) for it and try to eliminate options wherever possible
Round 2 - Technical Interview
Around 60 minutes after the aptitude test, selected candidates were called for technical interviews. We were expected to carry a hard copy of our resume.
I was the last candidate to be interviewed in my panel and had 4 others going before me so I had ample time to revise some important topics.
My preferred roles were:
Junior Analyst Software Engineer
Junior Analyst Analytical Verification
My technical interview began at around 5:00 pm and lasted till around 6:30 pm
As I entered the interview room, the interviewer asked me how I was and how the test went.
I answered this in detail explaining how each section of the test went for me.
The interviewer started looking at my resume and asked me a few questions based on it.
Questions:
What is AWS and what services does it provide?
What do you know about AWS EC2 and S3?
Have you learned C programming?
To which, I replied yes and told her that we were taught DSA in C during our 3rd semester. I explained how creating custom data types in C(using struct) was tedious as it did not follow DRY principles.
This directed the interview toward the need for Object-Oriented Programming and its features. The next few questions were as follows:
What is a class?
What is an object?
What is inheritance?
What are the 4 pillars of OOPs?
I was asked to implement a class Complex for complex numbers and implement a method to find and return the product of 2 complex numbers
After a good QnA on Java, I was asked the leet code problem maximum subarray
Then I was asked a few questions on SQL:
What is unique constraint?
What is indexing?
Why is indexing used? What are its benefits?
A few queries related to aggregate functions, GROUP BY and nested subqueries were asked
At the end, I was asked a puzzle
Then the interviewer asked me if I had any questions for her. I asked a couple of questions after which my interview was over.
After the technical interview, only 21 out of 57 candidates were selected for HR interview.
Tips for technical interview:
Explain each step and every line of code/logic you think
Even if you don't write any code, just speak out about what you are thinking and how are you approaching the problem
This shows that you're trying to solve the problem as well as explain to them your thought process behind it
The interviewer may also nudge you in the right direction if you're going wrong
Always research about the company and have some questions ready for them
Round 3 - HR Interview
What is your family background?
Tell me about your internship experiences
Do you prefer frontend development more than backend? (As most of my work was frontend oriented)
Why ISS?
What are your hobbies? (Apart from tech and work)
Which language do you prefer more? Java/Python?
How would you travel to the office daily?
Are you comfortable with relocation?
Are you more comfortable with React or Angular?
Do you have any questions for us?
The HR interviews ended at 10 pm. The results were out by 11:26 pm and, 15 out of the 21 candidates were selected for a full-time role at ISS.
Tips
Make sure to have a good intro as it sets the tone for the interview. Try to mention your strengths with concrete examples/experiences
Before starting to write anything on paper/computer, try to explain your thought process behind it
Make sure you are loud and confident with your answers
