-# Google Interview University
|
|
|
|
-*(formerly known as Project 9894)*
|
|
|
|
-
|
|
|
|
-### What is it?
|
|
|
|
-
|
|
|
|
-This is my multi-month study plan for going from web developer (self-taught, no CS degree) to
|
|
|
|
-Google software engineer. Don't let that offend you if you are a web developer. I'm speaking
|
|
|
|
-from my experience, not yours.
|
|
|
|
-
|
|
|
|
- This long list has been extracted and expanded from Google's coaching notes, so these are the things
|
|
|
|
- you need to know. There are extras at the bottom, but this is the list. No shortcuts.
|
|
|
|
-
|
|
|
|
-## Why use it?
|
|
|
|
-
|
|
|
|
-I'm following this plan to prepare for my Google interview. I've been building the web, building
|
|
|
|
-services, and launching startups since 1997. I have an economics degree, not a CS degree. I've
|
|
|
|
-been very successful in my career, but I want to work at Google. I want to progress into larger systems
|
|
|
|
-and get a real understanding of computer systems, algorithmic efficiency, data structure performance,
|
|
|
|
-low-level languages, and how it all works. And if you don't know any of it, Google won't hire you.
|
|
|
|
-
|
|
|
|
-When I started this I didn't know a stack from a heap, didn't know Big-O anything, anything about trees, or how to
|
|
|
|
-traverse a graph. If I had to code a sorting algorithm, I can tell ya it wouldn't have been very good.
|
|
|
|
-Every data structure I've ever used was built in to the language, and I didn't know how they worked
|
|
|
|
-under the hood at all. I've never had to manage memory, unless a process I was running would give an "out of
|
|
|
|
-memory" error, and then I'd have to find a workaround. I've used a few multi-dimensional arrays in my life and
|
|
|
|
-thousands of associative arrays, but I've never created data structures from scratch.
|
|
|
|
-
|
|
|
|
-But after going through this study plan I have high confidence I'll be hired. It's a long plan. It's going to take me
|
|
|
|
-months. If you are familiar with a lot of this already it will take you a lot less time.
|
|
|
|
-
|
|
|
|
-### How to use it
|
|
|
|
-
|
|
|
|
-Everything below is an outline, and you should tackle the items in order from top to bottom.
|
|
|
|
-
|
|
|
|
-I'm using Github's special markdown flavor, including tasks lists to check my progress.
|
|
|
|
-
|
|
|
|
-I check each task box at the beginning of a line when I'm done with it. When all sub-items in a block are done,
|
|
|
|
-I put [x] at the top level, meaning the entire block is done. Sorry you have to remove all my [x] markings
|
|
|
|
-to use this the same way. If you search/replace, just replace [x] with [ ].
|
|
|
|
-Sometimes I just put a [x] at top level if I know I've done all the subtasks, to cut down on clutter.
|

-## Prerequisite Knowledge
|
|
|
|
-
|
|
|
|
-This short section were prerequisites/interesting info I wanted to learn before getting started on the daily plan.
|
|
|
|
-
|
|
|
|
-You need to know C, C++, or Java to do the coding part of the interview.
|
|
|
|
-They will sometimes make an exception and let you use Python or some other language, but the language
|
|
|
|
-must be mainstream and allow you write your code low-level enough to solve the problems.
|
|
|
|
-You'll see some C, C++ learning included below.
|
|
|
|
-
|
|
|
|
-There are a few books involved, see the bottom.
|
|
|
|
-
|
|
|
|
-Some videos are available only by enrolling in a Coursera or EdX class. It is free to do so.

-## The Daily Plan:
|
|
|
|
-
|
|
|
|
-Each subject does not require a whole day to be able to understand it fully, and you can do multiple of these in a day.
|
|
|
|
-
|
|
|
|
-Each day I take one subject from the list below, watch videos about that subject, and write an implementation in:
|
|
|
|
- C - using structs and functions that take a struct * and something else as args.
|
|
|
|
- C++ - without using built-in types
|
|
|
|
- C++ - using built-in types, like STL's std::list for a linked list
|
|
|
|
- Python - using built-in types (to keep practicing Python)
|
|
|
|
- and write tests to ensure I'm doing it right, sometimes just using simple assert() statements
|
|
|
|
- You may do Java or something else, this is just my thing.
|
|
|
|
-
|
|
|
|
-Why code in all of these?
|
|
|
|
- Practice, practice, practice, until I'm sick of it, and can do it with no problem (some have many edge cases and bookkeeping details to remember)
|
|
|
|
- Work within the raw constraints (allocating/freeing memory without help of garbage collection (except Python))
|
|
|
|
- Make use of built-in types so I have experience using the built-in tools for real-world use (not going to write my own linked list implementation in production)
|
|
|
|
-
|
|
|
|
-I may not have time to do all of these for every subject, but I'll try.
|
|
|
|
-
|
|
|
|
-You don't need to memorize the guts of every algorithm.
|
|
|
|
-
|
|
|
|
-Write code on a whiteboard, not a computer. Test with some sample inputs.
|
|
|
|
-Then test it out on a computer to make sure it's not buggy from syntax.

|
|
|
- - https://www.lynda.com/Developer-Programming-Foundations-tutorials/Resizable-arrays/149042/177108-4.html
|
|
|
|
- - [x] Implement a vector (mutable array with automatic resizing):
|
|
|
|
- - [x] Practice coding using arrays and pointers, and pointer math to jump to an index instead of using indexing.
|
|
|
|
- - [x] new raw data array with allocated memory
|
|
|
|
- - can allocate int array under the hood, just not use its features
|
|
|
|
- - start with 16, or if starting number is greater, use power of 2 - 16, 32, 64, 128
|
|
|
|
- - [x] size() - number of items
|
|
|
|
- - [x] capacity() - number of items it can hold
|
|
|
|
- - [x] is_empty()
|
|
|
|
- - [x] at(index) - returns item at given index, blows up if index out of bounds
|
|
|
|
- - [x] push(item)
|
|
|
|
- - [x] insert(index, item) - inserts item at index, shifts that index's value and trailing elements to the right
|
|
|
|
- - [x] prepend(item) - can use insert above at index 0
|
|
|
|
- - [x] pop() - remove from end, return value
|
|
|
|
- - [x] delete(index) - delete item at index, shifting all trailing elements left
|
|
|
|
- - [x] remove(item) - looks for value and removes index holding it (even if in multiple places)
|
|
|
|
- - [x] find(item) - looks for value and returns first index with that value, -1 if not found
|
|
|
|
- - [x] resize(new_capacity) // private function
|
|
|
|
- - when you reach capacity, resize to double the size
|
|
|
|
- - when popping an item, if size is 1/4 of capacity, resize to half
|
|
|
|
- - [x] Time
|
|
|
|
- - O(1) to add/remove at end (amortized for allocations for more space), index, or update
|
|
|
|
- - O(n) to insert/remove elsewhere
|
|
|
|
- - [x] Space
|
|
|
|
- - contiguous in memory, so proximity helps performance
|
|
|
|
- - space needed = (array capacity, which is >= n) * size of item, but even if 2n, still O(n)

|
|
|
|
- - https://www.coursera.org/learn/data-structures-optimizing-performance/lecture/QUaUd/in-the-real-world-lists-vs-arrays
|
|
|
|
- - [x] why you should avoid linked lists:
|
|
|
|
- - https://www.youtube.com/watch?v=YQs6IC-vgmo
|
|
|
|
- - [x] Gotcha: you need pointer to pointer knowledge:
|
|
|
|
- (for when you pass a pointer to a function that may change the address where that pointer points)
|
|
|
|
- This page is just to get a grasp on ptr to ptr. I don't recommend this list traversal style. Readability and maintainability suffer due to cleverness.
|
|
|
|
- - https://www.eskimo.com/~scs/cclass/int/sx8.html
|
|
|
|
- - [x] implement (I did with tail pointer & without):
|
|
|
|
- - [x] size() - returns number of data elements in list
|
|
|
|
- - [x] empty() - bool returns true if empty
|
|
|
|
- - [x] value_at(index) - returns the value of the nth item (starting at 0 for first)
|
|
|
|
- - [x] push_front(value) - adds an item to the front of the list
|
|
|
|
- - [x] pop_front() - remove front item and return its value
|
|
|
|
- - [x] push_back(value) - adds an item at the end
|
|
|
|
- - [x] pop_back() - removes end item and returns its value
|
|
|
|
- - [x] front() - get value of front item
|
|
|
|
- - [x] back() - get value of end item
|
|
|
|
- - [x] insert(index, value) - insert value at index, so current item at that index is pointed to by new item at index
|
|
|
|
- - [x] erase(index) - removes node at given index
|
|
|
|
- - [x] value_n_from_end(n) - returns the value of the node at nth position from the end of the list
|
|
|
|
- - [x] reverse() - reverses the list
|

|
|
|
|
- - [x] Implement using linked-list, with tail pointer:
|
|
|
|
- - enqueue(value) - adds value at position at tail
|
|
|
|
- - dequeue() - returns value and removes least recently added element (front)
|
|
|
|
- - empty()
|
|
|
|
- - [x] Implement using fixed-sized array:
|
|
|
|
- - enqueue(value) - adds item at end of available storage
|
|
|
|
- - dequeue() - returns value and removes least recently added element
|
|
|
|
- - empty()
|
|
|
|
- - full()
|
|
|
|
- - [x] Cost:
|
|
|
|
- - a bad implementation using linked list where you enqueue at head and dequeue at tail would be O(n)
|
|
|
|
- because you'd need the next to last element, causing a full traversal each dequeue
|
|
|
|
- - enqueue: O(1) (amortized, linked list and array [probing])
|
|
|
|
- - dequeue: O(1) (linked list and array)
|
|
|
|
- - empty: O(1) (linked list and array)

-- Notes:
|
|
|
|
- - There are three basic ways to represent a graph in memory:
|
|
|
|
- - objects and pointers
|
|
|
|
- - matrix
|
|
|
|
- - adjacency list
|
|
|
|
- - Familiarize yourself with each representation and its pros & cons
|
|
|
|
- - BFS and DFS - know their computational complexity, their tradeoffs, and how to implement them in real code
|
|
|
|
- - If you get a chance, try to study up on fancier algorithms:
|
|
|
|
- - Dijkstra's algorithm

|
|
|

- - https://en.wikipedia.org/wiki/A*_search_algorithm
|
|
|
|
