InfoObjects Java Developer Interview Questions
& Process

So there were like 3 rounds in total. First, there was a group discussion. After that, a paper-pencil coding round. Finally, a technical interview where they asked questions mostly about Data Structures and Algorithms, and also about my projects.

The interview process started with an online aptitude round held in college. Then, there was a group discussion (GD) round at their office, and the topic was whether GD is an elimination round or not. After that, a coding test was conducted with a 45-minute time limit, where I had to solve three coding questions and write three SQL queries on pen and paper. The coding questions were of easy to medium difficulty, covering recursion, k-smallest elements from an array, and the coin change problem. The SQL queries involved joins and subqueries. Next, Technical Round 1 began with 'tell me something about yourself,' followed by questions on the singleton design pattern in Java and its implementation, the database implementation of IRCTC, more Java and OOPS concepts, and some linked list questions like reversing a linked list and removing duplicates. The interviewer was very helpful and provided hints. Technical Round 2 focused on projects, with some Java and data structure questions at a great level. Some HR questions were also asked. The interviewer was very supportive throughout. Technical Round 3 involved more data structure questions and puzzles. Finally, I was selected for the Java Developer position, with both internship and FTE offers.

I applied online and they invited me for a face-to-face interview. The interview has 3 rounds. The first two are technical rounds, the first one with two developers and the second one with the director. The last one is an HR round.
