Google interview preparation guide

Here is the article from mtu.edu. 

How to succeed: 

At Google, we believe in collaboration and sharing ideas. Most importantly, you'll need more information from the interviewer to analyze & answer the question to its full extent. 

• * It’s OK to question your interviewer. 
• * When asked to provide a solution, first define and frame the problem as you see it. 
• * If you don't understand - ask for help or clarification. *
•  If you need to assume something - verbally check it’s a correct assumption! 
• * Describe how you want to tackle solving each part of the question. 
• * Always let your interviewer know what you are thinking as he/she will be as interested in your process of thought as your solution. Also, if you're stuck, they may provide hints if they know what you're doing. 
• * Finally, listen - don't miss a hint if your interviewer is trying to assist you! 

5) What is Google looking for?: 

"We are not simply looking for engineers to solve the problems they already know the answers to; we are interested in engineers who can work out the answers to questions they had not come across before." 

Interviewers will be looking at the approach to questions as much as the answer: 

• * Does the candidate listen carefully and comprehend the question? 
• * Are the correct questions asked before proceeding? (important!) 
• * Is brute force used to solve a problem? (not good!) 
• * Are things assumed without first checking? (not good!) 
• * Are hints heard and heeded? 
• * Is the candidate slow to comprehend / solve problems? (not good!) 
• * Does the candidate enjoy finding multiple solutions before choosing the best one? 
• * Are new ideas and methods of tackling a problem sought? 
• * Is the candidate inventive and flexible in their solutions and open to new ideas? 
• * Can questioning move up to more complex problem solving? Google is keen to see really high quality, efficient, clear code without typing mistakes. Because all engineers (at every level) collaborate throughout the Google code base, with an efficient code review process, it’s essential that every engineer works at the same high standard.
