What type of coding questions are asked in Google interview?
Google mostly asks pure Data Structures and Algorithms based questions in the coding interview. Other CS core topics are not asked in google interviews. You need to be proficient in DSA to clear the Google coding interview. You can do so by practicing the google asked problems..
Data Structure and Algorithm Interview Questions for Google Interview
How do you find the duplicate number on a given integer array?
How do you find the largest and smallest number in an unsorted integer array?
How do you identify duplicate numbers in an array if it consists of multiple duplicates?
Arrays
Arrays are one of the most fundamental data structures in programming and computer science
Strings
A string is an ordered sequence, or string, of characters. It is usually considered a data type and is often included as part of language primitives
Linked Lists
A linked list is a data structure used to store a collection of data elements. In this way, it is similar to an array. However, unlike an array
Stacks and Queues
Stacks and queues are similar and complementary in many ways
Trees
A tree is an abstract hierarchical data structure. It is represented by a group of linked nodes, with a single root node. Each node can have zero or multiple children
Graphs
A graph is an abstract data structure represented by vertices connected by edges. Vertices are also known as nodes
Maps
A map is a data structure that allows us to access a value by key. This is in contrast to an array that allows us to access a value by index
Heaps
A heap is a tree-based data structure that implements a priority queue. A priority queue functions much like a regular stack or queue

What are data structure interview questions?
Data structure interview questions are a core part of software engineer interviews at companies such as Facebook, Google, or Amazon
That's why we've compiled a comprehensive list of 73 typical questions grouped by type (arrays, strings, linked list, etc
) and included links to high quality solutions
What data structure coding problems are asked at Google interviews?
Strings are another important data structure around which coding problems are asked at Google’s interviews
Let’s look at some data structure interview questions on Strings
For a given String S, write a code to reverse the string without disturbing the individual words
Google Data Structure Interview Questions on Arrays
For a given array of size N-1, containing integers in the range from 1 to N, write a program to find the missing element in the array.
For a given array containing positive integers, write a code to return the sum of the elements of the array.
For a given unsorted array of size N, write a code to rotate it anticlockwise by D elements.

Group of four floating barges
The Google barges were a group of four floating barges built between 2010 and 2012, intended by Google to serve as an interactive space where people can learn about new technology, possibly as luxury showrooms for Google Glass and other products on an invitation-only basis. Google halted work on the barges in late 2013 and began selling off the barges in 2014.
