Virtualbox blue screen of death error code 0x0000003b

February 12th, 2017 No comments

If you get a blue screen of death when using Virtual box its because hyperV and virtual box don’t player well together. You can disable hardware acceleration on vbox or do the following in windows:

bcdedit /set hypervisorlaunchtype off

This is going to break hyper v stuff.

I found this info on this guys site:

Most Popular Amazon questions

May 27th, 2014 1 comment

Based on my algorithm here are the 20 most popular questions that were asked during Amazon interviews:

Why Amazon?  
Linked list  
System design questions.  
Tell me about a time you failed.  
Why do you want to work for Amazon?  
What questions do you have for me?  
Design Question  
A lot of questions like “tell me about a time you ….”  
The excel exercise was specially tough for me. It is NOT related to finance.  
Describe a binary tree ?  
What do you do when people say no to you  
on data structures  
Search Tree  
The design problem  
Tell me about a time you used data.  
Tell me a time when you had to design a system?  
find common ancestor in binary tree(Not binary search tree)  
“Tell me about yourself”  
Write a code to find out if a tree is a binary search tree.  
Binary tree traversal  

Yes they do seem kind of generic, but I guess that is the case with many things.
