What is the context of the problem?
Are there any constraints or limitations?
What tools or programming languages can be used?
- Q5. You will be given dimensions of a bigger rectangle and smaller rectangle,derive a formula to get how many smaller rectangles fit into the bigger rectangle
- Ans.
Derive a formula to determine how many smaller rectangles fit into a bigger rectangle given their dimensions.
Calculate the number of times the smaller rectangle can fit into the bigger rectangle horizontally and vertically
Divide the width of the bigger rectangle by the width of the smaller rectangle to get the horizontal count
Divide the height of the bigger rectangle by the height of the smaller rectangle to get the ve...
- Q6. How many points are required to draw a rectangle
- Ans.
At least 4 points are required to draw a rectangle.
A rectangle has 4 sides and 4 corners, so at least 4 points are needed to define those corners.
The points must be arranged in a specific order to form a closed shape with 4 sides.
Additional points can be used to add details or modify the shape of the rectangle.
The number of points required may vary depending on the software or tool used to draw the rectangle.
- Q7. What will be the new coordinates of a rectangle points if rectangle length and breadth is scaled and write a program to calculate the coordinates of corner points of scaled rectangle
- Ans.
Answering how to calculate new coordinates of a scaled rectangle and providing a program for it.
To calculate new coordinates, multiply the original coordinates by the scaling factor
Scaling factor can be calculated by dividing the new length/breadth by the original length/breadth
Program can take input of original coordinates, scaling factor, and output new coordinates
Example: Original coordinates: (0,0), (0,5), (5,5), (...
- Q8. Lastly a puzzle: i dont remember the question
Interview Preparation Tips
Experience: The test had three sections:
1.aptitude:It was like any other aptitude test,all it takes is a bit of practice to crack all the questions
2.C programming:Basics of c were asked,outputs of some programs,u have to be thorough with concepts of c
3.Electronics:The company hired for both profiles: 1. PDK:software
and 2.Logic library:hardware,so this electronics section was also there,questions are mostly Network analysis,cmos logic,digital logic,vlsi etc
u should have good basics to get the electronics questions of course they are not very hard,but not too easy
Tips: practice aptitude,basics of c programming and also basics of electronics
Duration: 1 hour 30 minutes
Total Questions: 60
Round: Test
Experience: after 1st round i was shortlisted to this technical round,i was asked this question, i suggested that i will convert that number into a string and check whether string has a dot or not to check if it is float or int,the interviewer was not very impressed but was ok and asked few small questions and promoted me to next round
Tips: If u crack test with top marks,the technical rounds will be very easy,because the interviewers do not ask tough questions for people who cracked written test with high marks
Round: Technical Interview

- Q7. What is the width of a tree? How will you calculate the width of the tree?
- Ans.
The width of a tree is the maximum number of nodes at any level in the tree.
To calculate the width of a tree, we can perform a level order traversal and keep track of the maximum number of nodes at any level.
We can use a queue data structure to perform the level order traversal.
At each level, we count the number of nodes in the queue and update the maximum width if necessary.

The selection of the appropriate function is determined at compile-time, based on the sta...
- Q3. What is dynamic polymorphism?
- Ans.
Dynamic polymorphism is the ability of an object to take on many forms based on the context it is used.
