 ### 2. Introduction
 
 || Things |
 |-|-|
-|**Do's**|Introduce yourself in a few sentences under a minute or two.|
-||Mention interesting points that are relevant to the role you are applying for.|
-||Sound enthusiastic! Speak with a smile and you will naturally sound more engaging.|
-|**Don'ts**|Spend too long introducing yourself. The more time you spend talk the less time you have to code.|

 ### 3. Upon Getting the Question
 
 || Things |
 |-|-|
-|**Do's**|Repeat the question back at the interviewer.|
-||Clarify input format and range.|
-||Work through a small example to ensure you understood the question.|
-||Explain a high level approach even if it is a brute force one.|
-||Improve upon the approach and optimize. Reduce duplicated work and cache repeated computations.|
-||Think carefully, then state and explain the time and space complexity of your approaches.|
-||If stuck, think about related problems you have seen before and how they were solved. Check out the [tips](../algorithms) in this section.|
-|**Don'ts**|Ignore information given to you. Every piece is important.|
-||Jump into coding straightaway.|
-||Start coding without interviewer's green light.|
-||Appear too unsure about your approach or analysis.|

 ### 4. During Coding
 
 || Things |
 |-|-|
-|**Do's**|Practice good coding style. Clear variable names, consistent operator spacing, proper indentation, etc.|
-||Defensive coding. Check for nulls, empty collections, etc.|
-||Explain what you are coding/typing to the interviewer, what you are trying to achieve.|
-||Type/write at a reasonable speed.|
-||Write in a modular fashion. Extract out chunks of repeated code into functions.|
-||Use the hints given by the interviewer.|
-||Practice whiteboard space-management skills.|
-||Demonstrate mastery of your chosen programming language.|
-|**Don'ts**|Remain quiet the whole time.|
-||Spend too much time writing comments.|
-||Use extremely verbose variable names.|
-||Copy and paste code without checking.|
-||Interrupt your interviewer when they are talking. Usually if they speak, they are trying to give you hints or steer you in the right direction.|
-||Write too big (takes up too much space) or too small (illegible) if on a whiteboard.|

 ### 5. After Coding
 
 || Things |
 |-|-|
-|**Do's**|Scan through your code for mistakes as if it was your first time seeing code written by someone else.|
-||Check for off-by-one errors.|
-||Come up with more test cases. Try extreme test cases.|
-||Step through your code with those test cases.|
-||Look out for places where you can refactor.|
-||Reiterate the time and space complexity of your code.|
-||Explain trade-offs and how the code/approach can be improved if given more time.|
-|**Don'ts**|Immediately announce that you are done coding.|
-||Argue with the interviewer.|
