I applied through college or university. I interviewed at HashedIn by Deloitte (Cochin) in Apr 2025
Interview
The interview was conducted as a one-day session consisting of three rounds in total. Prior to the interviews, there was an Online Assessment (OA) which included:
1 Easy-level question
1 Medium-level question
1 Medium-Hard-level question
Round 1: Technical Interview – DSA & Core CS Concepts
The first round focused entirely on Data Structures and Algorithms, along with core computer science concepts like Operating Systems. I was asked questions on:
Graphs and Dijkstra’s Algorithm
A DSA problem involving HashMaps, with the constraint to solve it in less than O(n) complexity
While some candidates received LeetCode Hard problems in this round, I was fortunate to get a problem closer to LeetCode Medium difficulty.
Round 2: System Design + SQL
The second round was a System Design interview where I was asked to design a Library Management System. This included:
Designing database tables
Defining IDs, relationships, etc.
Writing relevant SQL queries based on the schema I designed
The focus was on clarity, real-world practicality, and query optimization.
Round 3: Behavioral Interview
The final round was a Behavioral Interview. Out of the 12 candidates who made it to this round, 10 were finally selected. This round is intense — the interviewers grill you to assess your honesty, attitude, and fit within the team. The best approach is to stay honest, be yourself, and stay composed even under pressure.
Interview questions [1]
Question 1
One of the most memorable and challenging questions I was asked came during the first technical round. They asked me to solve a HashMap-related problem with a strict constraint:
"You must solve this in less than O(n) time complexity."

Interview
HashedIn by Deloitte – Campus Recruitment Experience (SDE & SDET)
HashedIn by Deloitte visited our campus for SDE and SDET roles. I applied, and my resume was shortlisted for the online assessment.
Online Assessment
Total candidates: ~700
Candidates shortlisted for interviews: 66
The test consisted of 3 coding questions:
Easy
Medium
Hard
I successfully solved the Easy and Medium problems. In the Hard problem, I passed several test cases but not all. Based on my performance, I was shortlisted for the interview rounds.
Day 2 – Interview Process
Round 1 – Technical (Coding + Database + SQL)
This round primarily focused on coding skills and database concepts.
Questions asked:
1. Database Design

3. Coding Problems
Minimum Window Substring
String decoding problem:
Input: 3[a2[bc]]
Output: abcbcabcbcabcbc
I performed above average and was advanced to the next round.
Round 2 – Database Design (In-Depth)
This round focused entirely on system design and database concepts.
Main Task:
Design a complete Movie Booking System including:
Fully normalized database schema
E-R Diagram
Relationships between entities
Constraints and optimizations
The interviewer:
Reviewed my design in depth
Suggested improvements
Asked SQL queries based on my schema
Discussed normalization decisions
Asked detailed questions about my internships and projects
Reviewed my resume line-by-line
There was no coding in this round.
Round 3 – HR Discussion
Two panelists conducted this round.
The discussion included:
Behavioral questions
Situational questions
Company-related questions
Cultural fit assessment
Career aspirations
Final Outcome
From our campus:
10 students were selected
