Round 1: Online Multiple Choice Questions
It comprised of two sections.
- First section consisted around 15-20 questions related to logical reasoning (Quantitative – Easy-medium-level) and lengthy paragraphs (Verbal reasoning – Difficult – owing to the time allocated). It had to be solved within 20 minutes.
- Next section consisted around 30-35 questions related to general programming concepts including but not limited to C programming, Output based questions, Determining time complexity, Computer Networks, Operating systems, Computer organisation-and-architecture. Questions were of Easy-medium level. This section had to be solved within 45 minutes.
30 students were shortlisted for further rounds.
Round 2: Coding
A problem statement was given. We had an option to select the language. 1 hour was allocated for this round. Frequently asked questions in this round are –
- Determine whether a given number is an Armstrong number,

Almost all of them were shortlisted for the next round.
Round 3: Technical round 1(Based on design issues)
All the students were given a question based on a case study – Inventory management system. It was a dialogue between a consultant and client. Our task was to come up with a class diagram and ER diagram. Perhaps 30 minutes was allocated for drawing. After that every student had a discussion with the interviewers about the design. All the requirements must be covered in the proposed design. It was a bit challenging, but once you know how to draw a class diagram and entity diagram; and also to identify the key entities, you are good to go.

Round 5: HR/MR round
By far, this was the most challenging round. There were 2 interviewers. Many questions were situation-based. There was no right or wrong answer, they wanted to test the students EQ. In almost all questions a situation was presented to you and you had certain choices to pick from. You also had to justify your answer. In the end, there were few standard HR questions.
