Full Details
I gave three online assessment in a day, I applied for the position of data scientist,AI engineer,etc
1.
Assessment 1
* There are infinite array of integers consecutivelty, you are given the array and 1 integer to avoid and a every iteration you can either stay at i or i +j where i is the index and j is step number,
return the maximum index
* a string is beautiful if no two adjacent characters are either
1 the same, for example \'aa\'
2 adjacent in the alphabet, for example \'ef\'
find the minimum number of operations required to make a string beautiful(requires DP)
2.
Assessment 2
* 2nd question of the 1 first assessment minimum operation to make a string beautiful
* very easy SQL question on Aggregation
3.
Assessment 3
* similar to leetcode SLINDING WINDOW MAXIMUM only difference being i have first find out the minimum and then the maximum of the minimun therefore single value will returned unlike the SLINDING WINDOW MAXIMUM question
* very easy SQL question on join
I am surprised that IBM is asking hard question as on my preparation for it people including leetcode discuss told me they ask easy question except one

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