HashedIn by Deloitte Interview Experience
First round was OA, it was for 90 minutes and had 3 questions:
- 1 easy and 2 medium LeetCode-type questions.
- But there were no test cases to check if your code was right or not.
- You had to code and check against custom test cases of your own, find the edge cases, and then submit the result.
**
Technical Interview Round 1**
The next day, I was shortlisted for the 1st round of the technical interview. It started with:
-
Introduction \u2013 They asked about my passion and extracurricular activities.
Core subjects like OOPS, C++, and DBMS:
-
Diamond inheritance in C++.
-
Types of Joins in SQL.
-
Virtual Constructor concept.
-
SQL Query \u2013 Finding the second largest element in a table.
Coding Questions \u2013 The panel had 2 interviewers (one was asking most of the questions, the other was a bit dormant). I had to write code on paper (only logic explanation was also acceptable).
-
Longest Palindromic Subsequence (LCS variation): Given a string, reverse it and find LCS (from
LeetCode Striver Sheet).
- After solving the optimal approach, they further asked me to find the second largest palindromic subsequence. This was tricky, and I took some time, asked for hints, and was eventually able to solve it, though not in the most optimal way.
- Another
DP question on array partition, which I was able to solve.
**
Technical Interview Round 2**
In this round, they first asked some basic coding questions:
-
Detecting Cycle in a Linked List (Hare and Tortoise method).
Implementing Stack using Queue.
System Design:
-
Designing a high-level Flipkart-type app with features they mentioned.
- I created
API call flow diagrams and database schema with foreign key references.
- They then asked me to normalize the database, guiding me along the way. I made progress but couldn\u2019t complete it exactly as expected.
- A
SQL query based on the tables I created.
HR Round
This was the most chill round:
-
Discussion on projects from my resume \u2013 why I built them, the purpose, and technical details.
Casual Questions like
CR7 vs Messi, family background, and personal interests.
Situational Questions like \u201CWhat would you do if you received \u20B910 crore today?\u201D.
If you reach the
HR round, you\u2019re likely selected. They selected everyone who made it this far.
Preparation Tips:
-
Practice LeetCode (Striver Sheet) for
DP, Strings, and Array problems.
Revise OOPS, DBMS, and SQL queries.
- Learn basic System Design (API design, Database Normalization).
- Mention only the technologies you are confident in on your resume.
Overall, it was a well-structured process, testing
DSA, Core CS, and System Design skills.
