• Given an array where each element is the money a person has, and there is only Rs. 3 note. We need to check whether it is possible to divide the money equally among all the persons or not. If it is possible, then find the Minimum number of transactions needed.
• Find the next greater number with the same set of digits.

Round 2:

F2F Technical Interview

• The diameter of a binary tree.
• C++ concept like polymorphism,inheritance,function overloading,virtual function,virtual destructor etc.
• Next greater Element (full code)
• A sorted Array has been rotated r times to the left. Find the minimum in the least possible time(O(logn) expected).

Round 3:

Write a program to print “Hello” and “World” infinitely using two threads, such that one thread prints the String “Hello” and the other prints “World”!

• Why sleep() cannot be used?
• Why have you used the synchronized keyword?
• How will a deadlock occur in this program?
• What will be the solution for breaking the deadlock?
• Write a program in Java to find whether a given tree is a subtree of another one or not?

Round 4: HR Round

• Tell me something about yourself?
• How were the interviews?
• How were the interview questions?

Snapdeal Campus interview Process

Recently Snapdeal came to our campus.

Online Test:

• 22 (MCQ) +2 (Coding) in 1 hr. Test conducted on hackerrank
• 22 MCQ had almost 10 aptitude and 12 C output based questions.

Coding Question:

• Given a string of parenthesis only, check if it’s valid or not.
• Given points of two lines segments A(x1,y1 x2,y2) & B(x3,y3 x4,y4) find whether the 2 segments intersect or not.

Round 1:

• A little discussion on Final Year Project and the summer training.
• Basics of DBMS, the difference between RDBMS and DBMS, Keys and its types, indices, joins and its types with an example, normalization, and denormalization.
• A simple program to check whether a number is a palindrome or not.

Round 2:

• How would you design DBMS for Snapdeal’s website’s shoe section? Now if you want to break it into Sports and Casual Shoe further would you break the DB into two or add another entity?
• DNS – Domain name servers: what are they, how do they operate?

Round 3:

• There are two sorted arrays. First one is of size m+n containing only ‘first’ m elements. Another one is of size n and contains n elements. Merge these two arrays into the first array of size m+n such that the output is sorted.
• Find the square root of a number
  I gave an iterative O(n) solution, and He told me to optimize: I did it in O(logn) with binary search.

Further, optimize to O(1): I got stuck, after a lot of discussion on different techniques he gave me a hint that he would be using my function a lot of times than I immediately told him to use hash maps and save the previous results.

HR Round:

If you have made till here, that means you are selected. The HR guy in snapdeal is the coolest HR I have met. He asked me the name of the companies that have hired me till now, and I gave him their names.
