Full Details
Procedure: 1 written test, 1 paper coding round, 2 technical + HR round. 1st Written Test: This was really a good written test including C/C++, OS , aptitude, DS and Algo. 2nd Written Test: There were 7 coding question in 45 min :D 1. You are given two strings like where first string is like “a?b$c+ ", here A? means either A comes zero time or more than one time B$ means either B comes one time or not occur C+ means either C comes zero time or more than one time. The second string is a normal string, check whether the second string follows the first string pattern. 2. You are given a M x N matrix of non-negative integer, you need to find a square K x K matrix such that sum is maximum in that square matrix. (0<=K<=M,N) 3. WA procedure to delete Kth node from front and from end. (when you delete from front then in reaming you need to delete from end). 4. How will you design Tic-Toc game? 5. You are given random() function which return a random number from 1 to 5 now you need generate random number using these function from 1 to 7 with having equal probability of occurring of numbers b/w 1 to 7 . Rest I forget :( I was the topper of this written test. 1st interview Round They start asking me some general question like about myself, area of interest. About my project in detail, they also told me to write a parallel sorting procedure [bec. my project was on parallel computing] 1. Design parking slot. 2. Design Library (books management), which DS will you use? 3. You are given a matrix of integers and your task to find an element which is maximum in the row and minimum in column. 4. Discussion on 2nd written test questions. 5. Discussion on Cloud computing and how will implement it. 6. Where you use cloud computing in daily life. 7. What you know about java. How much time will you take to learn java? How java is better than C++, where java is appropriate as compare to C++ and where C++ is more appropriate then java. Write a sample code in java to perform task (question no. 3) Rest I forget, there were two more questions on Real life application. 2nd Interview Round This was coding round with one more candidate (he was my classmate). Following question need to be code 1. You are given a matrix such that it is sorted in row as well in column. You need to find an element “k” in it with minimum complexity. 2. A sorted, rotated array was given and need to find an element in it (he was surprised when I wrote that code in single scan in O(logn) time complexity). Hurray, I got Placed. :) This article is compiled by Nitin Gupta . Many Many congratulations to Nitin for his selction.
About This Question
This is a reported interview question from a transbit interview for a eng manager role during the recruiter round reported in 2017.
It covers the following topics: Strings, Networking, Sorting, Probability Stats, Arrays, Matrix .
About Transbit Interview Reports
This question was reported by a candidate who interviewed at Transbit. 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 Transbit are the higher-signal extractions to take from this report.
For broader preparation context, the Transbit 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 Transbit reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Transbit 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 Transbit 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.
