Basics on C program, Networking & Core relates questions
Interviewer will point out and ask you a set of questions on Networking concepts, C programming & questions related to core subjects.
TCP is connection-oriented, reliable, and slower, while UDP is connectionless, unreliable, and faster.
TCP is connection-oriented, meaning a connection must be established before data can be transmitted.
TCP is reliable, as it ensures all data is received in the correct order without errors.
TCP is slower than UDP due to the overhead of establishing and maintaining connections.
UDP is connectionless, meaning data can be se...
Pointers in C are variables that store memory addresses. They are used to access and manipulate data directly in memory.
Pointers are declared using the * symbol, like int *ptr;
Pointers can be used to pass variables by reference to functions
Pointers are commonly used for dynamic memory allocation with functions like malloc() and free()
Pointers can be used to create data structures like linked lists and trees

Joins in SQL are used to combine rows from two or more tables based on a related column between them.
Joins are used to retrieve data from multiple tables based on a related column between them
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
INNER JOIN returns rows when there is at least one match in both tables
LEFT JOIN returns all rows from the left table and the matched rows from the right table

Objects are instances of classes in OOPs. Classes are blueprints for creating objects with attributes and methods.
Objects are instances of classes
Classes are blueprints for creating objects
Classes define attributes and methods for objects
Example: Class 'Car' with attributes like 'color' and methods like 'drive'

After round 1 there was a break of 15 mins and the coding round started.
We had a choice to attempt the exam in R language & SQL or python & sql
I chose python and sql
It had 8 questions 4 python and 4 sql

The task is to find the length of the longest common subsequence between two given strings.
Use dynamic programming to solve this problem efficiently.
Create a 2D array to store the lengths of longest common subsequences of substrings.
Iterate through the strings to fill the array and find the length of the longest common subsequence.
Example: For strings 'abcde' and 'ace', the longest common subsequence is 'ace' with leng

Determine if it is possible to accommodate all passenger trips within a car's capacity without exceeding it at any point.
Iterate through each trip and keep track of the total number of passengers in the car at each point.
Check if the total number of passengers exceeds the car capacity at any point.
Return 'True' if all trips can be accommodated within the car capacity, otherwise return 'False'.
Round duration - 20 minutes

After two technical round interviews, the last round was a hr interview. The whole process can take up one whole day or more and your interview can be at any time
My process started at 5 pm and ended at 10:30 pm
All the interviewers were very friendly no pressure.
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 conditions F(1) = F(2) = 1
.
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 iterate to calculate subsequent Fibonacci numbers.
Time complexity can be optimized to O(N) using dynamic programming.
Example: For N = 5, the 5th Fibonacci number is 5.
Tip 1 : Be fast ans accurate on your aptitude amd verbal tests.
Tip 2 : In coding round, depending on the difficulty of the questions the time in which you complete solving them should decrease .If almost everyone can solve them timming comes in to the equation for shortlisting
Tip 3 : While submitting your resume, please be honest about the projects you have done and do not bluff about it because in the interview when you ate drilled abt it, they can catch you easily.
Tip 4 : be confident and answer every question to the best of your ability and if u don't know something, tell them you don't know abt it .
Tip 1 : Research the company and put the most revalent projects and skills that the company os looking for specifically
Tip 2 : Do not bluff or lie on your resume. It show's during the interview.
