Disk scheduling algorithms manage the order in which read/write requests are serviced on a disk.
Common disk scheduling algorithms include FCFS, SSTF, SCAN, C-SCAN, LOOK, and C-LOOK.
FCFS (First-Come, First-Served) serves requests in the order they arrive.
SSTF (Shortest Seek Time First) prioritizes the request closest to the current head position.
SCAN moves the disk arm from one end to the other, serving requests along t...

The editor and the environment was great and not disturbing like many have.
They had their own test cases to check the scope of our code.
Given an array of numbers, the task is to find the maximum sum of any contiguous subarray of the array.
The first line of input contains the size of the arr...
Find the maximum sum of any contiguous subarray in an array of numbers in O(N) time.
Use Kadane's algorithm to find the maximum subarray sum in O(N) time.
Initialize two variables: maxEndingHere and maxSoFar to keep track of the maximum sum.
Iterate through the array and update the variables accordingly.
Return the maxSoFar as the result.

It had only mcq questions but we could not navigate through the questions it had some reasoning and some dbms topics along with data structure ,memory ,cache memory and other topics
To find the age of an employee from the personal details table in SQL, you can calculate the difference between the current date and the employee's birthdate.
Use the DATEDIFF function in SQL to calculate the difference between the current date and the employee's birthdate.
Divide the result by 365 to get the age in years.
Consider leap years for more accurate results.

The interviewer was polite and asked few questions from data structures and some from DBMS and some web question and about my project.
Primary key uniquely identifies a record in a table, while candidate key can also uniquely identify a record but is not chosen as primary key.
Primary key is chosen as the main unique identifier for a table
Candidate key is a unique key that could also be chosen as primary key
A table can have multiple candidate keys but only one primary key
Example: In a table of students, 'student_id' could be a primary key while 'email'

The interviewer asked me about my project and told me to describe myself in one word and justify that and asked my personal skills and asked some technical questions as well
Pickling is a process of preserving or extending the shelf life of food by storing it in a solution of salt, vinegar, or brine.
Pickling involves submerging food in a solution of salt, vinegar, or brine to preserve it.
Common examples of pickled foods include cucumbers (pickles), onions, and cabbage.
Pickling can also enhance the flavor of food by infusing it with spices and herbs.
The acidity of the pickling solution help...
Tip 1 : Must go for interviews questions present online for topics you have mentioned.
Tip 2 : Be updated with the latest technology and have those concepts clear in your mind and do prepare your projects and have a clear picture of it to explain that
Tip 3 : For preparing algorithms do practice them, that is the best way and lastly you can check your knowledge by solving mcqs and quizzes of those topics to have confidence.
Tip 1 : Do not mention anything in your resume that you are not confident about. And prepare your resume well before interview.
Tip 2 : Mention your projects and technical skills and your github link to showcase your project portfolio that will have a great impression

This was an easy round which went really smooth.
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 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).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10
2 3 5 7
N = 20
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
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
