I appeared for an interview before Oct 2020.
Round duration - 40 minutes
Round difficulty - Medium
Asked about time complexity of algorithm, puzzles, DBMS, cutting edge technologies etc. What are indexes?
Given an array of integers ARR
of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.
Consider flipping a sub-array from index i to j and calculate the count of 1s in the resulting array.
Return the maximum count of 1s obtained by flipping a sub-array at most once.
Round duration - 20 minutes
Round difficulty - Medium
Asked 1 standard algorithm
You are provided with a 2-dimensional matrix having N
rows and M
columns, containing only 1s (land) and 0s (water). Your goal is to determine the number of islands in t...
Count the number of islands in a 2D matrix of 1s and 0s.
Iterate through the matrix and perform depth-first search (DFS) to find connected 1s.
Mark visited cells to avoid redundant traversal.
Increment island count whenever a new island is encountered.
Tip 1 : prepare for competitive programming
Tip 2 : know about standard algorithm
Tip 3 : must be good with dbms
Tip 1 : must have projects, which you can explain to them
Tip 2 : have things on resume, that you are totally certain about.

I appeared for an interview in Feb 2021.
Joins are used to combine data from two or more tables based on a related column.
Types of joins include inner join, left join, right join, and full outer join.
Inner join returns only the matching rows from both tables.
Left join returns all rows from the left table and matching rows from the right table.
Right join returns all rows from the right table and matching rows from the left table.
Full outer join returns all row...

Leet code medium level question
Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
Hashmap uses a hashing function to map keys to indices in an array.
It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.
Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");
I applied via Walk-in and was interviewed in Feb 2022. There were 3 interview rounds.
There where two paper one was of maths and second paper was of engligh.
There where ten person in one GD, topic was provided us by them.
