Interview Preparation Tips
Experience: general wareness consists of one liner questions that are easy but the time provided would be less... say 20 mins for 40-50 questions..this section basically checks your speed
aptitude consists of general aptitude questions basically maths , geometry and reasoning which are also easy and time provided is sufficient
Tips: dont loose your calm and avoid any silly mistakes...... try to improve your speed by regular practice coz the questions provided are easy and rest assured that you are capable enough to solve then right but all that you need to go ahead in this cut throat competition is you speed ,your confidence and your calm mind
P.S - this tip applies to almost all aptitude tests for any campus recruitment
Round: HR Interview
Experience: Hr questions are basically those questions to which you could answer easily coz they are questions about you.its as if you are introducing yourself to a stranger but then try to be a bit witty in your answers ..thats what catches the attention of the interviewer the most
Tips: do not go to an interview with the same old conventional mugged up answers....IT should be like you are meeting a person for the first time and you need to impress him/her with your answers
Round: Technical Interview
Experience: the technical interview was a bit of everything infact.. YOU need to know your branch basics...you need to know the maths studied in 9th and 10th standard....you need to know a bit of programming (not compulsory)....and ya try to go through some google puzzles before going for the interview...or at least try to use a bit of your logical sense for such questions
Tips: I know it becomes hard to be able to be a master in all fields....but at least dnt try to look dumb or arrogant by just saying i dont know....show them the attitude that you are atleast trying to solve the question even if you dont know how to ..beforehand,,,,,,and a huge tip is that you are the one who actually decides which way your interview turns to...the way you answer,,the terms you use ...etc is what helps the interviewer to frame the next question from your answer itself..so always try to bring up those points about which you want your interviewer to ask questions to you
Skills: puzzle solving skills, programming skills, maths(basics)

3 Questions
- Q1. Given 9 identical coins what number of minimum comparisons between them will be required to determine one of the heavier coin
- Q2. Make a program for this where input was no. of coins and output is no. of comparisons required.
- Ans.
Program to calculate no. of comparisons required based on no. of coins input.
Create a function that takes the input of no. of coins
Use a loop to compare each coin with every other coin
Increment the comparison count for each comparison made
Return the total comparison count
- Q3. If i am having sorted array and then i am inserting a new element into the array so which algorithm should be used to minimize time complexity
- Ans.
Binary search algorithm should be used to minimize time complexity.
Binary search algorithm has a time complexity of O(log n).
It is efficient for searching in a sorted array.
The algorithm works by repeatedly dividing the search interval in half.
Example: If the array is [1, 3, 5, 7, 9] and we want to insert 6, we can use binary search to find the index where 6 should be inserted.
Once we find the index, we can shift the e...
Interview Preparation Tips
Experience: It was basic aptitude test with two parts
part i) General test: 40 questions, 20 minutes
part ii) Technical test: 30 questions, 20 minutes
both of the test were easy.
Tips: practice for time and work, time speed and distance, some what geometry and mensuration, and mainly search for 3dplm and geometric previous year questions
Duration: 40 minutes
Round: Technical Interview
Experience: It was interview of 32 candidates --> 2 day process
My interview took around 60-70 minutes. Initially I was little nervous, so interviewer told me to be relax and calm (this process is ice breaking process so that candidate can give answers in his normal way). then he started with introduce yourself, for all interviews this is the first question.
my introduction was not completed as my actual interview began with my achievements. First question was about codevita what is codevita, what types of problem were asked and all that (Codevita is competition organised by TCS every year and it was mentioned in my resume), so after listening to problem statement he changed the problem in his way and asked me to make a program. he asked me one question on java but I am unable to recall it right now. Next was puzzle -> Given 9 identical coins what number of minimum comparisons between them will be required to determine one of the heavier coin.
I solved this puzzle and i think i was the first one to answer it correctly, so interviewer played the next move.. and that was to make a program for this where input was no. of coins and output is no. of comparisons required. (this was the important question of my interview due to which i got selected).
he asked about my family, my future plan specially post graduation (he tried to asked me 2-3 times about my post graduation plans)
Tips: Be confident,
always be ready for data structure, C, puzzles.
Round: Group Activity
Experience: this was unique round took around 2hr.
it was group discussion on puzzle and one program between all candidates and HR also.
Puzzle: there are 25 horses and you have to find top 3, but problem is track has a size of 5 horses so what is minimum no. of races requiered to find top 3.
Program: Date validation (this took around 1 and half hour)
overall motto behind this round was checking candidate's thinking capability, and how he behaves in a group.
Tips: Be confident and share your thoughts, as i think every company basically focuses on how good your thought process is.
Skills: Data Structure, logical reasoning, programming
College Name: Government College Of Engineering, Aurangabad
Funny Moments: in my second round, for program of date validation
every one was talking about creating a program, but i am bit lazy, so i gave my answer that create a reference of Date class and insert the details using that reference if error occured then that date is not valid
on this HR replied me "anyways you are selected "
and after the end of session everyone came to me to shake hand but i was thinking that was joke and i did not shook hand with anyone.

- Q1.
Nth Fibonacci Number Problem Statement
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows:
F(n) = F(n-1) + F(n-2), with initial conditionsF(1) = F(2) = 1.Input:
... - Ans.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
- Q2.
Prime Numbers Problem Statement
Given a positive integer
N, your task is to determine and return all prime numbers less than or equal toN.Input:
N = 10Output:
2 3 5 7Example:
Input:
N = 20
Out...
- Ans.
Implement a function to return all prime numbers less than or equal to a given positive integer N.
Create a function that takes a positive integer N as input
Iterate from 2 to N and check if each number is prime
Use a helper function to determine if a number is prime
Return an array of all prime numbers less than or equal to N
- Q3. What is a merge join in SQL?
- Ans.
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i
