I applied via Recruitment Consultant and was interviewed in Sep 2020. There were 3 interview rounds.
The lapping location for top and bottom bars of a beam is typically at the mid-span of the beam.
The lapping location is where two reinforcement bars are overlapped and connected to ensure continuity and strength in the beam.
For top bars, the lapping location is usually at the mid-span of the beam, where the bending moment is maximum.
For bottom bars, the lapping location is also at the mid-span of the beam, but it can v...
The internal plastering thickness and mix ratio vary depending on the type of surface and desired finish.
The thickness of internal plastering typically ranges from 12mm to 20mm.
The mix ratio for internal plastering is usually 1:4 (cement:sand) or 1:6 (cement:sand) depending on the strength requirement.
For smooth finishes, a finer mix ratio of 1:3 (cement:sand) may be used.
Gypsum plaster is commonly used for internal pl...
The crank length for slab bar is the distance between the center of the slab bar and the center of the crank.
The crank length is determined based on the design requirements and specifications of the slab.
It is usually measured in millimeters or inches.

Sum up the trapped water at each bar to get the total trapped water for the entire array.
You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find the minimum time required to rot all fresh oranges adjacent to rotten oranges.
Create a queue to store the coordinates of rotten oranges and perform BFS to rot adjacent fresh oranges.
Track the time taken to rot all fresh oranges and return -1 if not all fresh oranges can be rotten.
Update the grid with the new state of oranges after each second.
Handle edge cases such as empty grid or no fresh oranges present.

Implement a queue using stacks following FIFO principle.
Use two stacks to simulate a queue.
For enQueue operation, push elements onto stack1.
For deQueue operation, if stack2 is empty, pop all elements from stack1 and push onto stack2, then pop from stack2.
For peek operation, if stack2 is empty, pop all elements from stack1 and push onto stack2, then return top of stack2.
For isEmpty operation, check if both stack1 and st...

This round had 2 coding questions - first one related to Binary Tree and the second one was a simple question from Bit Manipulation. This was followed by some questions from OOPS.
You are given a Binary Tree, and you need to determine the length of the diameter of the tree.
The diameter of a binary tree is the length of the longest path betwe...
The task is to find the diameter of a binary tree, which is the length of the longest path between any two end nodes in the tree.
Traverse the tree to find the longest path between two nodes.
Keep track of the maximum diameter found during traversal.
The diameter may not necessarily pass through the root node.
Consider both left and right subtrees while calculating the diameter.
Example: For input 1 2 3 4 -1 5 6 -1 7 -1 -1

The fir...
The problem involves determining if it is possible to reorder the digits of a given integer to form a power of 2.
Iterate through all possible permutations of the digits of the given integer.
Check if any of the permutations form a power of 2.
Return 1 if a valid permutation is found, else return 0.
Advantages of OOP include code reusability, modularity, and easier maintenance.
Code reusability: Objects can be reused in different parts of the program, reducing redundancy.
Modularity: OOP allows for breaking down complex problems into smaller, more manageable parts.
Easier maintenance: Changes to one part of the codebase do not necessarily affect other parts, making maintenance easier.
Encapsulation: Data hiding and ab...
Access specifiers define the level of access to class members in Object-Oriented Programming.
Access specifiers include public, private, protected, and default
Public members are accessible from outside the class
Private members are only accessible within the class
Protected members are accessible within the class and its subclasses
Default access is when no access specifier is specified

Queue can be implemented using two stacks by maintaining the order of elements in the stacks.
Create two stacks, let's call them stack1 and stack2
When an element is enqueued, push it to stack1
When an element is dequeued, pop all elements from stack1 and push them to stack2
Pop the top element from stack2 and return it as the dequeued element
If stack2 is empty, repeat step 3
To get the front element of the queue, peek the
Left join returns all records from left table and matching records from right table. Full outer join returns all records from both tables.
Left join is used to combine two tables based on a common column.
In left join, all records from the left table are returned along with matching records from the right table.
If there is no match in the right table, NULL values are returned.
Example: SELECT * FROM table1 LEFT JOIN table...
Magic functions are special methods in PHP that start with __. Autoloading is a way to automatically load classes.
Magic functions are used to handle certain events in PHP, such as object creation or property access.
Autoloading allows PHP to automatically load classes when they are needed, without requiring manual includes.
Magic functions can be used in conjunction with autoloading to dynamically load classes or handle
Given three sorted arrays, find common elements.
Create three pointers to traverse each array
Compare the elements at the pointers and move the pointer of the smallest element
If all pointers point to the same element, add it to the result and move all pointers
Repeat until any pointer reaches the end of its array
Check if a number is a power of 2 or not.
A power of 2 has only one bit set in its binary representation.
Use bitwise AND operator to check if the number is a power of 2.
If n is a power of 2, then n & (n-1) will be 0.
