Cadence Design Systems India hires freshers through campus drives and its global new-grad portal: an online test (aptitude, technical MCQs, coding), then three to four technical interviews and HR. Fresher interviews are heavy on C++ (virtual functions, copy constructors), data structures and puzzles, with digital basics such as latches, flip-flops, counters and NAND logic.
Who can apply
- Reported criteria: 65% throughout Class X, XII and graduation; CGPA 6.5 or above for B.Tech
- Branches reported: CSE, IT, ECE and EE
- Student and new-grad roles span product engineering, design engineering and software engineering

Questions to expect in Cadence Design Systems India interviews
Drawn from reported fresher tests and interviews (sources below), with short answers. Practise more on placd.
What is the difference between a latch and a flip-flop?
A latch is level-sensitive: while enable is active its output follows the input (transparent), so glitches can pass through. A flip-flop is edge-triggered: it samples only at the clock edge, so the output changes at most once per cycle. A master-slave flip-flop is two latches on opposite clock phases.
Design a 3-bit counter that counts 1 -> 3 -> 5 -> 7 -> 1.
The states are 001, 011, 101, 111, so the LSB Q0 is always 1: tie it high (or set it on reset). Q2Q1 counts 00, 01, 10, 11 like a normal 2-bit up counter: D1 = Q1' (toggle every clock) and D2 = Q2 XOR Q1 (toggle when Q1 = 1). Initialise to 001.
Build AND and OR gates using only NAND gates.
NOT: tie both inputs together, NAND(A,A) = A'. AND: a NAND followed by a NAND inverter, so AND(A,B) = NAND(n,n) with n = NAND(A,B), 2 gates. OR, by De Morgan: invert each input, then NAND, so OR(A,B) = NAND(NAND(A,A), NAND(B,B)), 3 gates.
In a sorted array where every element appears twice except one, find the single element in O(log n).
Binary search on pair alignment. Before the single element, pairs start at even indices (a[2k] == a[2k+1]); after it, they start at odd indices. With lo = 0, hi = n-1, while lo < hi: take mid, make it even; if a[mid] == a[mid+1], set lo = mid + 2, else hi = mid. Answer a[lo].
What is the size of an empty class, and what changes when you add a virtual function?
An empty class has size 1 byte, so that distinct objects have distinct addresses. Adding a virtual function adds a hidden vptr to each object pointing to the class's vtable, so the size becomes the pointer size: typically 8 bytes on a 64-bit system, 4 on 32-bit. The vtable itself exists once per class.
Write a copy constructor for a class with an int and an int* member. What is shallow vs deep copy?
The default copy constructor copies the pointer value (shallow copy), so both objects share one int; destroying one leaves the other dangling and causes a double delete. A deep copy allocates new memory: A(const A& o) : x(o.x), p(new int(*o.p)) {}. Follow the rule of three: also define the destructor and copy assignment.
About Cadence Design Systems India hiring
Does Cadence hire ECE and EEE freshers in India?
Yes. Reported eligibility for Cadence campus drives covers CSE, IT, ECE and EE. Cadence says its student and new-grad roles span product, design and software engineering. Many fresher roles are C++ software on EDA tools, so ECE students should prepare C++ and data structures alongside digital logic.
What does Cadence ask freshers in interviews?
Mostly C++ and data structures: virtual functions and class sizes, copy constructors and deep copy, new vs malloc, binary search and tree problems, plus puzzles. Digital questions also appear: gates from NAND, latches vs flip-flops, and small counter designs such as a 1-3-5-7 counter.
How much does Cadence pay freshers in India?
Cadence does not publish fresher pay. Levels.fyi reports a median of about ₹16.8 LPA for Software Engineer I, its entry level in India. Treat it as a reported figure; campus offers vary by role and college.
