Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.

free-form answer

computer science (algorithms, architecture, data structures, and operating system theory)

1. under what circumstances would you use an array over an linked-list (or other data structure)?
2. what is the average search time for a binary search tree?

• what can impact a binary search tree's performance metrics?
• how can these algorithmic vulnerabilities be mitigated?

3. what are at least two approaches to hash table insertion collisions?

• what are the algorithmic costs to each?

4. what is the difference between a process and a thread?

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
