Anusha N
I applied via Campus Placement and was interviewed in Apr 2023. There were 3 interview rounds.
Online Test
There were 3 colleges writing the online test(pool campus).Cut off was about 70% with no backs .This was probably the hardest of the entire recruitment process. It had about 20 technical and 20 aptitude questions and questions had NEGATIVE MARKING.
Technical questions were majorly focused on Circuit theory, network theorems, dependent source problems, time constant calculations, RC circuits and its graphs, and a very few problems on communication theory and signals and systems/DSP. The questions are actually easy provided you have solved those topics before hand . Do understand the behavior of RC circuits by watching a few videos on YouTube. Understand dependent source problems and solve problems based on those topics. If you study the subject Electric Circuit Analysis(ECA), which was part of our syllabus it would be sufficient. Again, don't study everything in ECA, focus on the topics mentioned above.
Aptitude questions were quite straight forward with mathematics involved, and some English/vocabulary based questions. Attend the placement training properly, you can grasp most of the concepts and attend many of the online tests with ease.

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
