Hi, I was recently(June'23) interviewed for the Software Developer position for Cadence Design Systems (Location: Noida). Have a year of experience. Following were interview rounds/questions-
Round 1 Telephonic Round with HR. Focus was on:- Reason for Change? Previous Compensation || Expected Compensation. Experience in C++.
Round 2 Coding Round || Taken by Principal Engineer having 7+ YOE. Kth Largest Element in a BST. Modified InOrder Traversal followed with Level Order Traversal - (Start from Bottom) Find a triplet with the given sum. Questions on C++ Concepts- Can the constructor be private followed by questions on Singelton Class Questions on Inheritance, Polymorphism Storage Classes in C/C++ etc. It was expected to come up with solutions having efficient Time and Space Complexity with iterations.
Round 3 Puzzle Round || Taken by Technical Manager having 11+ YOE. Camel and Banana Puzzle Create an AND (&) operation using OR (|) and Inverse (~) Operator 10 Identical Bottles of Pills Detect Loop in LL? How does Floyd's algorithm work? Had to explain the proof using diagrams. Mislabelled Jars Questions on C++ Pointer Concepts. Questions on Reference, Pointer Increment, etc. This round was tougher than expected. If you are going for an interview with cadence, I will strongly suggest you go through all the puzzles listed in GFG. It may or not be asked but yes, if you haven't practiced puzzles before, it will be tough to crack logic during the interview.
Round 4 Tech + Fitment Round || Taken by Sr. Director- India Head having 21+ YOE. Questions were to reverse the word in the incoming stream ensuring special characters were handled accordingly. You can't use Stack or other libraries. Implement custom functions on your own. This question alone took 10-15 min, various special cases were introduced later. Check given coordinate lies within the rectangle. Optimise the equation with compiler point of view where x is variable and abcdef are constatnts y=ax5 + bx4 + cx3 + dx2 + ex + f Now comes the fitment questions Why do you want to switch? How was your feedback on the previous company? Did any conflict happen during the project? How did you handle conflict? What sort of constructive feedback you used to get? Explain all the projects you did in the company. How was your bonding with co-workers? Describe your strengths and weaknesses. Expected compensation, Previous Compensation? Any other offers? I had another offer also, so the discussion was quite interesting here. Why do you want to join cadence over that? How do you ensure your motivation?? This round was tiring. I think I was asked all the typical fitment questions that exist. Suggestions:- Go through all the interview questions article on GFG. Brush Up C++ Concepts. Must Practise GFG Puzzles Prepare for typical fitment questions Final
Outcome My expected compensation did not align with the offer provided.

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