First Round(Aptitude + Coding): It was a combination of aptitude and 3 coding questions. 2 coding questions were easy and one was medium. Make sure that you give your best in this round because fewer people move to round 2. Second Round(Technical Round): I felt that the technical round was pretty easy as the interviewer asked about my college projects and then asked me what was my favorite subject. I said OS. Then he asked all the basic questions related to OS some of them are. What are sockets? What is Paging? What is Deadlock? Then he asked me Networking questions which were: What is Internet? What happens when you type "www.google.com" in the browser? I was shortlisted for the HR round. Third Round(HR Round): So this interview is taken by Hitachi's senior leadership. So he started with my introduction about my background. Then he moved to puzzles How to Measure 45 minutes using two identical wires? https://puzzlersworld.com/aive-hi-puzzles/cricket-puzzle-2/ These were the puzzles he asked, I answered them. Then he just wanted to check my current affairs knowledge. So he asked me some current affairs questions.

About Hitachi Consultancy Interview Reports
This question was reported by a candidate who interviewed at Hitachi Consultancy. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Hitachi Consultancy are the higher-signal extractions to take from this report.
For broader preparation context, the Hitachi Consultancy interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Hitachi Consultancy reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Hitachi Consultancy Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Hitachi Consultancy reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
