Hello everyone, this is my experience of the selection procedure of Paxcel Technologies. The first round was a MCQ test with 40 questions covering topics ranging from Data Structures, Operating Systems, Computer System Architecture, Networks, aptitude. Level of questions ranged from easy to moderate. Not very difficult to clear this round although 50% negative marking was tricky.
Coding Round: There were 2 questions: 1. Given a 5 digit number and 2 operators ( + and - ), find the minimum and maximum possible positive integers using digits from the number and the 2 operators.
Example: 12345,+,-. Possible combinations may be: 1+2-345, 1-2+345 (344 : Maximum). Absolute values of results of all operations was to be considered. 2. Given an input string ( 200 character limit, character set: a - z ), find all possible square sub strings. Square sub string: Strings formed by concatenation of any string.
Example: abab( formed by concatenating ab with ab). Technical Interview 1: Questions related to arrays, link lists, trees were asked. Operating systems questions was the major focus point. Topics related to memory leak, segmentation, paging were also discussed. Discussions about technologies worked on, projects worked on and general interests were also a major part of the interview. Technical Interview 2: More operating systems related questions were asked. Topics included paging, thrashing, framing, schedulers, scheduling algorithms. General concepts like sockets and ports were also discussed. Again interviewer focussed on technologies used and discussions related to devops engineering, automation engineering and tools like ansible, docker, selenium were also discussed. Later HR related questions were discussed. Some students also had a HR +
technical round with a panel of 5 members! Overall level of interview was moderate and main focus point being operating systems and projects undertaken and technologies knowledge. Geeksquiz and other geeksforgeeks questions were of great help. Galvin is the go-to book for operating systems.
About Paxcel Interview Reports
This question was reported by a candidate who interviewed at Paxcel. 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 Paxcel are the higher-signal extractions to take from this report.
For broader preparation context, the Paxcel 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 Paxcel reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Paxcel 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 Paxcel 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.
