Power2SME visited our campus for full-time role as well as 6-month intern role for master student. The 1st online round was hosted on mettl platform, consisting of 70 MCQs (Aptitude, reasoning, technical and English) and 1 code. It had 2 coding questions and 20 MCQs. Q1. Given an unsorted array A, find the maximum possible summation for the visit either from A[i] to A[0] or from A[i] to A[n-1] but the condition is that you have to add equal amount from each elements over the range. There were 3 technical and 1 HR round and Every interview round started with the cliche “tell me about yourself” and ended with “do you have any questions”. In technical rounds basically they start with your interest and then ask their questions. Mine was DS and Algorithm so some of questions are as: 1) Check whether a linked list is palindrome or not. Try to explain each and every possible way and explain time and complexity of each step. 2) Check whether two binary tree are mirror image of each other or not. 3) Reverse a given Stack, again with each and every approach but they were interested in O(1) space complexity. 4) Construct BST with the help of pre order and post order. Discussed many corner cases. 5) Swap two numbers with different approaches and finally we ended up to the solution in 1 line. 6) Given a n*n matrix having all elements as 0 or 1 and all rows are sorted. You have to find the row with maximum 1 and also that number of 1s. 7) Design power() function in O(logn). 8) Subset sum problem And they asked a lot of question on my project and many basic HR questions. I suggest you to be confident and have deep knowledge in your area of interest. My recommendation is geksforgeeks and you can use stackoverflow for different aspects of any problem. Thanks geeksforgeeks for such a huge platform for us.

About Power2sme Interview Reports
This question was reported by a candidate who interviewed at Power2sme. 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 Power2sme are the higher-signal extractions to take from this report.
For broader preparation context, the Power2sme 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 Power2sme reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Power2sme 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 Power2sme 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.
