I applied via Campus Placement and was interviewed in Jan 2016. There were 3 interview rounds.
Interview Questionnaire
5 Questions
- Q1. Reduction of 3D Kmap ?
- Ans.
Reduction of 3D Kmap involves simplifying a 3D truth table to minimize the number of logic gates required.
3D Kmap is a graphical representation of a truth table with three variables
Reduction involves grouping adjacent cells with the same output value
The goal is to minimize the number of groups and variables in each group
Simplification can be done using Boolean algebra or Karnaugh maps
Example: Reducing a 3D Kmap with in

Experience: The selection procedure is a test followed by tech interview and an HR interview.
The test had two parts:
Aptitude (common across all profiles)
A tech. test (separate for each profile)
Round: Interview
Experience: The tech interview was the important one and the HR interview was just about knowing the student and vice-versa. The tech interview was more concentrated on the basics and more importance was given to the approach of solving the problem rather than solving the problem itself.
No CGPA cutoff.
Round: Interview
Experience: Not very important.
General Tips: The work is well structured and executed. There is a lot of opportunity for more technical learning. Interns are also included into the teams and this helps the intern on knowing about the things going around them and gets an overall view of how things work.
As a whole, the work is very good, and exceeds all the expectations of the students.

Questions covering various aspects
(2 Questions)
- Q1. Design a mood 3 counter
- Ans.
A mood 3 counter is a device that tracks and displays the user's mood on a scale of 1-3.
Design a simple interface with 3 buttons for the user to input their mood (happy, neutral, sad)
Include a display screen to show the current mood level
Implement a reset button to clear the mood counter
Consider adding a visual indicator such as colored LEDs for each mood level
- Q2. What are the three states
- Ans.
The three states refer to the three fundamental states of matter: solid, liquid, and gas.
Solid: particles are closely packed together and have a fixed shape and volume (e.g. ice)
Liquid: particles are close together but can move past each other, taking the shape of their container (e.g. water)
Gas: particles are far apart and move freely, filling the entire space of their container (e.g. air)
