Linked Lists
Linked lists come up at Anduril as standard Mediums, on code-pair screens and technical screens alike. On a code-pair screen you write your own tests in the editor as well.
All three problems come down to moving pointers without losing a node. Draw the list before and after each change, then write the code to match.
The Anduril angleBring your own tests, and aim them at the pointers. Much of Anduril's autonomy and embedded code is C++ on real hardware, where a bad pointer can hang a loop or corrupt memory on a vehicle, so these rounds lean on edge cases. Test the empty list, a single node, a value at either end, and a list where every value is equal. The design round may ask for a doubly linked list too, and it checks the same insert and delete cases.
