Cadence interview :

Round 1 : Telephonic round with Manager. Manager discussed my current projects , technologies I was working on. Asked some basic C++ concepts , basics on design patterns , discussion on performance profiling , approach to debug crashes in the product. Looks like it was basic screening of my profile. Went for around 1 hour.

Round 2 : C++ round

1. Rule of 5 in c++
2. Implement my own unique_ptr class. The interviewer expected me to write a templatized class.
3. Diamond problem of multiple inheritence.
4. Questions on unordered_map vs map. Asked to implement unordered_map with handling of hash collision.
5. Asked to write a class to handle arithmatic operations on integer of any size. I think interviewer was expecting big integer class.

Round 3 : Algo / DS

1. Questions on DS were mostly either easy or medium level of leet code.
2. Asked questions on BST , graphs and linked lists.

Round 4 : Algo / DS and low level design

1. Question on how to design class hierarchy for a clock
   ---Interviewer expected to handle all use cases
2. Again some DS questions on BST and Graph. ( Upto LT medium)

Discussion on current project , what design patterns I can think of for software application. Discussion on strategy , observer and command design patterns.
