- Q1. Different gradient optimizations.
- Ans.
Different gradient optimization algorithms improve training efficiency in machine learning models.
Gradient Descent: Basic optimization algorithm that updates parameters in the opposite direction of the gradient.
Stochastic Gradient Descent (SGD): Updates parameters using a subset of training data at each iteration.
Mini-batch Gradient Descent: Combines features of both Gradient Descent and SGD by using a small batch of t...
- Q2. CNNs vs MLP vs RNNs
- Ans.
CNNs are used for image recognition, MLPs for simple classification tasks, and RNNs for sequential data like text or time series.
CNNs are best suited for image recognition tasks due to their ability to capture spatial dependencies.
MLPs are commonly used for simple classification tasks where the input features are independent of each other.
RNNs are ideal for sequential data like text or time series where the order of in...
- Q3. String match DP problem.
- Ans.
String match DP problem involves finding the longest common subsequence between two strings.
Use dynamic programming to solve this problem efficiently.
Create a 2D array to store the lengths of common subsequences.
Iterate through the strings to fill the array and find the longest common subsequence.
Example: Given strings 'ABCD' and 'ACD', the longest common subsequence is 'ACD'.

Interview Preparation Tips
Interview Preparation Tips
Experience: The selections process started with a presentation by the company where they introduced you to the environment of the company. It was followed by a written subjective test which basically tested your programming skills. Questions were based on arrays, classes and OOP concepts. Last part of the paper was an essay asking about the city you live. Total 3 questions were asked which had to answered in 25 minutes time. Total no. of students appeared for the test was around 30.
Round: Technical Interview
Experience: After the test only 5 students were shortlisted for interview. Interview for each candidate began with a technical round where they asked us to pick one programming language we are comfortable with. I picked C++. They asked me very basic concepts example Function overloading, Operator overloading, 2-D array concepts other OOP concepts.
Round: HR Interview
Experience: It went very smooth for me. They asked me what I know about the company. Though i couldn't remembered much I told them two points and then smiled. Then they asked me to tell me about myself and our NITK campus. I answered that aptly. Then they started asking serious questions i.e. if I want to go for higher studies, why am I not joining ARMY (I told them my father is in armed forces). Then they asked me if I want to work in Chennai or Bangalore, I told them Bangalore and also the reason behind it. After that, it was a casual interaction and I became quite sure about my selection.
General Tips: I think one thing which matters the most is your self-confidence. Hard-work and dedication are very important of-course but it is your confidence that separates you from other individuals. Also for most of the interviews they do not ask very big concepts, they will assess you on basic concepts, how much you know about the subject. So, be it any language, have your basic concept clear first and while giving interviews speak confidently.
This was my first campus interview I got selected and I cleared it. So yes, I was in a little shock and surprise to clear the interview.
Also one thing I forgot to mention was that the pointer cut-off for this company was 7.5 while I had only 7.11. Still I got selected. It does not matters much how much pointer you have. What matters at last is how much thorough you are with the subject. Well till morning I was not even sure if I am sitting for this company and by I got placed.
Skill Tips: Though there are huge resources of materials lying online and market, don’t run in all directions. Choose one book and an online source and start preparing it.
In my case I studied Sumita Arora for C++ and it proved to be quite beneficial for me. Also solve aptitude questions for programming available online like indiabix.com. It provides a lot of help in understanding and applying your concepts and also for time limit.
For aptitude question the best book available is "Quantitative aptitude by Arun Sharma".
For C++ language focus mainly on OOPS concepts, its features and basic building blocks like arrays, pointers etc.

Interview Preparation Tips
Experience: The test was conducted online. All the questions were of medium standard and easy to crack if we have patience for thinking.
English comprehension level is slightly below the standard of CAT. Those who have the habit of reading English news paper can easily crack the test.
Data analysis questions were also of medium standard. Those who have knowledge about graphs, bar & pie charts can easily crack the exam.
Tips: Practice Aptitude questions from R S Agarwaal book and CAT material.
Round: Technical Interview
Experience: Over all interview experience is cool. Interviewers never grilled on anything. In many cases they have helped me to arrive at answers.
Tips: Read C++ and Oops concepts from E Balaguruswamy text book.
For Data structures and algorithms read 'Data structures' by Yeshwant kanethkar.
Minimum knowledge about all the courses of your department will be an added advantage. This will help you to depict you are sincere in your studies and don't have any personal constraints in learning a new thing.
General Tips: Just be confident and believe in yourself. You will get through.
Skills: Programming skill in C++
