FICO Interview Experience

So today I got the opportunity to appear for the FICO Internship cum PPO interview for the “Software Quality Assurance” role Initially, I was quite nervous as this was the first interview I ever gave, but the interview went much better than expected. the interviewer seemed to be calm and gentle. As I entered the room, I greeted him and he asked me to introduce myself. after that, I was asked about my projects, where I had to explain the Problem Statement, Tech Stack used, etc. for the projects. then I was asked, “In which programming language are you most comfortable?”, to which I answered “Java”, followed by the reason for liking that language the most. then I was asked if I have any previous experience in Java, to which I told him that I know the basics of SpringBoot and mostly solve coding questions using Java.

After this, the interviewer gave me the question Find the second largest element in an array and asked me to code down the logic [the most efficient algorithm being in O(n)].

Then, the interviewer asked some theoretical questions from Java, which are as follows:-

• What makes Java different from other languages like C, and C++?
• Explain what is Map Interface in Java.
• If a key is present in a Map with a corresponding value, and we try to insert that key again with a different value, then what will happen?
•  What are Generics in Java?
•  What is the use of the final keyword?
•  What are the interface and the advantage of using them?

So, this is the overall experience that I got from this interview.

Since this role was mainly for Java Development, therefore the interview was focused on Java. Otherwise, in most of the interviews for the SDE Roles, questions from the Computer Science subjects like Operating Systems, Database Management Systems, and Computer Networks are also asked.
