Zomato Coding Round Questions

Here below we share all the Zomato Coding question that were asked in coding rounds for SDE.

  1. Find total number of set bit in numbers upto n.
  2. Reverse the each word of the given paragraph.
  3. WAP to find height of BST.
  4. Detect if two line segments intersect each other.
  5. Form the maximum number from the elements of the array.
  6. Write a code for a 2-D array such that it there’s a zero, it overwrites all the elements of the corresponding row and column as zero.
  7. Write a code to find the previous shorter element in an array.
  8. Given a world map such that all the places covered via land are represented by ‘L’ and rest by ‘W’. Since world is spherical hence rows and columns are cyclic (before row 1 row n comes and after row n row 1 same for column). Count the number of islands.

Zomato Technical Interview Questions (SDE)

DBMS

Here below we share all the Zomato DBMS question that were asked in Technical rounds for SDE.

  1. What is indexing and how is it implemented internally.
  2. Given two DBs A and B and one table T ( Columns C1, C2)in both DBs, C1 was primary key in them and C2 was another indexed column in DB B. Select query will run on both DBs i.e Select C2 from T where C1=X. Which DB will serve faster data

  9. Create a stack in java.
  10. Longest palindromic substring.
  11. WAP to check whether tree is symmetric or not.
  12. Find the sum of odd positioned nodes of a BST.

How To Prepare for Zomato Interview(SDE)

For DS and Algo : GeeksforGeeks, HackerRank & Ravindra Babu lectures. For OS, CN & DBMS : GATE Notes and GeeksforGeeks and sanchit jain videos for OS. OOPS concepts online. *Also know about some advanced DS concepts, their working and use cases like trie, segmented trees, splay trees, skip list, Red black trees, AVL etc. they won’t ask you to code them but just knowledge of the above stuff would help you to stand out of the crowd.Be through with your resume and make sure you can justify each and everything written in your resume
