HashedIn Interview Experience 2022
HashedIn by Deloitte had visited BIT Mesra in August 2021 for Intern + FTE role. There was a pre-placement talk scheduled on Zoom which all the registered candidates had to join. A total of 81 students had registered for the process.
Round 1: The first phase was coding, which had 3 questions of easy-moderate difficulty. As far as I know, only those who could solve all three were promoted to the next round
Questions in the coding round:
- You have rolled dice several times. The N roll results that you remember are described by an array A. However, there are F rolls whose results you have forgotten. The arithmetic mean of all the roll results is equal to M. What are the possible results of the missing rolls?
- Worker assigning problem – Given a string S, find out the maximum number of intervals where the number of ‘L’ shoes is equal to the number of ‘R’ shoes.
- Bit manipulation problem – Count number of 1s in the binary representation of multiplication of two integers.
18 students cleared the coding round and moved on to Technical Interview 1.
Round 2: Technical Interview 1
Time: 1 hr
- Intro
- Tech stack
- Pointer based output question (C++)
- Implement stack from 2 queues.
- Celebrity problem (solved by the graph)
- Rapid-fire questions on Java (moderate-high difficulty)
- Rapid-fire questions on DBMS, Networking, Operating systems.
8 students cleared Technical Interview 1 and moved on to Technical Interview 2.
Round 3: Technical Interview 2
Time: 1 hr
- Intro
- Projects
- An in-depth discussion on any one project of your choice.
- Write a program to efficiently reverse an input (first gave naive approach, followed by string split). At the last moment, I used stack which was the right answer.
- Merge two unsorted lists (used Quick Sort followed by Merging algorithm).
7 students cleared Technical Interview 2 and moved onto Fitment round (HR)
Round 4: Fitment round
Time: 25-30 mins
Intro
- Why HashedIn
- Team player or lone wolf
- Experience of teamwork
- How do you motivate peers
- A little intro about the company – HashedIn University
- Hobbies and Interests
Result: Selected
All 7 students cleared the HR interview and received an email the following day regarding the selection.
Tips:
- Solve moderate-level problems on GFG and Leetcode. It is more than enough for the coding round.
- Brush up on CS fundamentals for TI-1. Rapid-fire round is very challenging. The interviewer will change subjects very fast, so you need to keep up. They are friendly and will give you a few seconds to think for an answer.
- For TI 2, revise your project thoroughly. They may ask you questions based on the libraries and concepts used. I was asked in-depth questions about Elliptic Curve Cryptography (ECC) since my project was based around Cryptocurrency.
- HR interviewer was very chill. Just remain confident and you should be able to back everything on your résumé.
All the best!
