HashedIn Interview Experience | Off-Campus March 2021

  • Last Updated : 31 Mar, 2021

HashedIn came to our college in October. I cleared the coding round and then Technical Interview Round 1 but couldn’t clear Technical Interview Round 2 because I was not prepared at that time.

After that, I started preparing for upcoming placements. Luckily after 5 months, I got to know that HashedIn had started recruiting off-campus. I applied for it and after few days I got a mail that my resume has been shortlisted and my coding round was scheduled for 8 March.

Online Coding round: Three questions were asked in this round. The problems were related to String Manipulation, DP, and Trees. I was able to solve two problems.

On 10 March, I got a mail that I was selected for the Technical Interview Round 1 which was scheduled for 15 March.

Technical Interview Round 1: The interviewer started the interview by asking me to introduce myself and then about my projects. I was asked three questions:

  1. Add 1 to a number represented as a linked list(https://www.geeksforgeeks.org/add-1-number-represented-linked-list/)
  2. Different sorting algorithms. Describe selection sort, insertion sort and compare them.
  3. Working of dictionary in Python and problem related to it.

I was selected in this round and the next round was on 18 March.

Technical Interview Round 2: The questions asked in this round were:

  1. Fewest Number of coins that you need to make up that amount (https://leetcode.com/problems/coin-change/)
  2. Design an online book store schema and draw the class diagram for the tables and queries related to it.
  3. OOPs concepts like inheritance, polymorphism, etc. Runtime and compile-time polymorphism.

Usually, after clearing this round, there is an HR Round but for me, it was Technical Interview Round 3 scheduled on 24 March.

Technical Interview Round 3:

  1. I was given a Product and manufacturer database. I had to relate different tables using foreign keys and then write the query for the given problem.
  2. Length of the longest substring without repeating characters(https://www.geeksforgeeks.org/length-of-the-longest-substring-without-repeating-characters/)

I cleared this round and the HR round was on 25 March.

HR Round: The HR asked me several questions:

  1. Tell me about yourself?
  2. Family Background
  3. Why HashedIn?
  4. Why Computer Science Engineering?
  5. Have you solved any real-world problems? If yes, then describe them.
  6. What is your biggest achievement?
  7. Do you have any questions?

I got a mail on the same day that I have been selected.

I will be joining HashedIn on 12 April 2021.
