Interview Preparation Tips
Round: Test
Experience: The first round was in multiple choice format. Most of the questions were from I/O in C , C++ and Java. There were few questions on operating systems and other topics in CS. Most of them were easy and the only factor is time. You have exactly 30 mins to solve 15 MCQs.
Tips: Be prepared in C , C++ and Java. If you are new to any of these languages , at least have a look at the basic input output functions.
In my class they basically selected everybody to the coding round. However it is always good to write as best as you can since they look at cumulative score at the end.
Duration: 30 minutes
Total Questions: 15
Round: Test
Experience: There was a coding round for the selected students. In my class everyone was selected to this round.There were 2 questions :
1 ) Given a Binary tree find sum of data at all the boundary nodes. A boundary node was defined , which basically evaluates to any node on the left most path , right most path and the leaves.
2) Given 2 numbers in a linked list form i.e each digit of a number in a node of the linked list , return the linked list that is the difference of the two input linked lists.
Tips: Coding is only perfected by practice. Have a good understanding of Data structures and common algorithmic paradigms including DP , Divide and Conquer, greedy etc.
Duration: 60 minutes
Total Questions: 2
Round: Group Discussion
Experience: Here's the deal : The group of students selected are seated in a big room. A problem statement is put up as a power point slide ,and you are expected to come up with appropriate data structures and algorithms to solve the problem. There are mentors who assist you ( if needed ). You have to explain your approach and write a (psuedo) code for your idea.
In my case the problem statement was as follows :
"Consider a game as follows : There is a 4X4 size game board. On each slot in the board a dice is placed. The dice has a character ( a ,b ,c .. ) printed on it. There is a character on every side of the dice. Now find all the words that can be made (in the wordament game style ) by the characters on the top face of the 16 dices. Now also write a shuffle function that shuffles the board.
Tips: It was an easy backtracking question. If you can improve your data structure , it would fetch you extra points.
Duration: 60 minutes
Round: Technical Interview
Experience: Basically I applied for a machine learning profile. So all the technical questions were from basics of ML. If you have good basics in ML , the interview is very easy. I was doing ML this semester only. So he might have limited with basics :P
Tips: Tell your mentor if you are not aware of a particular approach to ML classification( or regression) . He ll teach you the basics(literally :P ) and then ask questions.
Round: Technical Interview
Experience: It is okay if you don't come up with great model. I only knew about Linear Regression and modeled it accordingly.
I took --- > Y = ( Demand/Availability) as my output variable and identified a few input parameters. He was satisfied with that :P
In the third question he elaborated a little more on Bias and variance.
Tips: Basic ML is more than enough.
General Tips: Be confident. Dress properly for interviews. If you get the internship more than happy. If not : remember this " Success is going from failure to failure WITHOUT losing enthusiasm"
Skills: Algorithms , Data Structures, Machine Learning, C, C++, Java
Duration: 2
College Name: IIT Madras
Motivation: My long term goal is to be a data scientist. So an ML profile at Microsoft was the best thing I could get now :P

Interview Preparation Tips
Round: Test
Experience: Fairly simple questions to be done in the time limit made it a reasonably good test to filter. There was a MCQ test with 15 questions(30min) followed by 2 programming questions(1hr) . The time for coding was ample while that for MCQ was apt.
Tips: Just brush the concepts of pointers, guess the output kind of questions. Basic sorting algorithms. Revision of the graph theory related algorithms will help you through out the selection process(both coding and MCQs).
Duration: 90 min minutes
Total Questions: 15+2
Round: Group Discussion
Experience: It was a beautifully constructed knapsack problem. They would want to see the way you approach the problem rather than the solution. They would help you if you are stuck.
Tips: Just stay cool , don't try to classify problem into the theorems or similar problems that you have come across before, rather see how you can approach, basically don't be in a hurry to apply all that you know.
Duration: 40min minutes
Round: Technical Interview
Experience: Popular questions again, they were particular about writing proper code and not just the pseudo code.
Tips: Just revise what you've done already if you are from cs, for non-cs I would advice to get thorough with standard things in graph theory , with coding as well theory , helps quite a lot.
Round: Behavioural Interview
Experience: The person that was interviewing was trying to discourage me by not paying attention

Interview Preparation Tips
Round: Test
Experience: It consisted of 20 questions primarily on C (What will be the output/error types). 3-4 of these questions were on basic logic, data structure, operating system etc. 30 minutes were given, which everyone found adequate. The test was not very difficult since I was thorough with books such as . Two codes were to be written, compulsorily in C. Both the questions were directly taken from the book Cracking. Question 1: A sorted array is given, but it is rotated an unknown number of times. Find an element in this array. Time complexity should be log(n). Array example: 15, 17, 19, 50, 1, 2, 6, 8. I did not know how to do it. I tried a modified binary search but it did not work for all cases. So I just used a normal for-loop (Linear Search)Question 2: Find the in-order successor of a node in a binary tree.
