KLA Tencor visited our campus in February. They took only Dual Degree(BTech + MTech) Computer Science students for the initial round. After the pre-placement talk, we had a coding test on hackerrank for 75 minutes. Web cam was enabled for monitoring and we were not allowed to switch tabs. Round 1 (Coding Round): We had 2 coding questions. 1st coding question was similar to a number of islands problem. It was an easy question. Find the size of the biggest cluster in the image where the image matrix is boolean (0 or 1). All test cases
passed https://www.geeksforgeeks.org/dsa/count-inversions-of-size-three-in-a-give-array/ . I wrote the brute force solution, and it
passed 10/12 test cases 7 people were shortlisted for the
next round.
Round 2 The second and final round was a workshop. The workshop was from 8 AM to 8 PM, where we were given a problem statement of industry level, and we had to come up with a solution to solve it. Mentors were assigned to us, and they checked our progress every hour via Airmeet (this was the platform used for the Workshop). At the end of the day, the candidates who solved the problem were selected as interns. Unfortunately, I couldn't solve the problem within the given timeframe. The solution to the problem involved a good amount of image processing. The challenging part of the workshop was understanding the problem statement and coming up with the approach for the solution. 3 people were selected after the workshop.

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