Round 2: Technical Interview – 1 (45 Minutes)

The first technical interview round was scheduled for the first week of April and was conducted over a Zoom call. This interview was scheduled with one of the Lead Software Engineer of Informatica. The interview involved:

1. Introduction
2. Discussion on Projects
3. Questions based on Java and OOPs.
4. Two Coding questions (Basic-Intermediate level)
5. Writing test cases for one of the projects.

In this round, I was asked in detail about Java and OOP concepts such as Encapsulation, Abstraction, Polymorphism and its types, Inheritance, Over-riding vs Overloading, Abstract classes, Interfaces, Constructors, static methods, main class, JDK, JVM, JRE, lambda expression, Singleton class, Keywords such as static, final, public, private, protected, super.
There were questions based on Design Patterns and threading concepts. Since in college, my minor course was Informatica, I was asked about Data Integration tools, ETL, MDM, Filter vs Router etc.

Apart from this, I was asked to write basic coding questions either in Java or Python. One question was calculating the factorial of a number and the other was based on the maximum and next maximum sum.
I was also asked to explain any one of the projects mentioned in my Resume and write some test cases.
After the interview, I asked for my feedback and the interviewer provided me with the same.
The interviewer was impressed with my interview and congratulated me for moving to the next round.

Informatica visited our LPU campus to hire Trainees/ Apprentices. About 360 students appeared for the drive, out of which 2 got selected from campus. Here’s my interview experience.
