HashedIn by Deloitte interview questions

I applied through my college campus. - Coding test: Coding assessment(offline college campus). They asked 3 coding questions(Easy, Medium, Medium). You needed to complete 2.5 or 3 questions to get selected for the next round(Although some students from my college were shortlisted for the interview even though they solved only 1 question.) I was shortlisted among 10 students from my college, and there where almost 100 students present at the office for an interview from different colleges. - Interview Round 1: (DSA questions, Questions related to your resume). They same 2-3 easy to medium DSA questions. You are supposed to solve those question in front of the interview while explaining the thought process for solving those questions(You have to write the code/pseudocode on a piece of paper). Later if time permits, they ask questions related to your resume. (If you are lucky enough and your interview is scheduled at last. You can ask the DSA questions to the candidates who gave an interview right before you. They don't change the DSA questions for next candidates. That might give you an unfair advantage and if your interview at first, you might be cooked.) They eliminate almost 60-70% of the candidates after the 1st interview round. Before elemination is declared, they provide lunch as well for free. - Interview Round 2: (System Design, DB design) They as you about your favourite app or the most used app and ask you to do a high level system design for that app. After that they might ask you to design the db for the same as well. - Interview round 3: (HR/ Fitcheck round): This is like a typical fit check round. Like why do you want to join, are you ready to relocate and those kinda questions. At my time, they gave offers to almost 15-20/100 candidates that appeared for the process.

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.
