Reddit reviews Elements of Programming Interviews in Python: The Insiders' Guide

Grinding problems, haha! I can't answer your more specific questions, but I'll distill the resources that I have found to be most useful. The types of questions will depend on wherever you are applying and you might not even get technical questions at some places.

• Elements of Programming Interviews
  
• CTCI
  
• leetcode
  
  I would start with CTCI then, if you feel like it, move on to Elements of Programming Interviews which (I think) has more difficult problems. All the while just grind problems on leetcode. Also, make sure to practice answering these questions without coding in an IDE. I have just been using a notebook and pencil. A whiteboard works too. Before beginning any sort of coding, you should have the general algorithm down that you will use to solve the problem.
  
  It also would be helpful to know how to implement / be familiar with the following:
  
  Data Structures
  
  
• Linked Lists
  
• Dynamic Arrays
  
• Hash tables / dictionaries (Definitely know how to use these)
  
• Binary Search Tree
  
• Queue
  
• Deque
  
• Stack
  
  Algorithms
  
  
• Binary Search
  
• Quicksort
  
• Mergesort
  
• Insertion Sort
  
• Dynamic Programming
  
• Bit Manipulation
  
• DFS
  
• BFS
  
• String Manipulation( reversing, detecting palindromes, word count, counting repeated words, comparing strings)
  
• A*
  
  
  OOP (define these)
  
  
• Interfaces
  
• Abstract classes
  
• Polymorphism
  
• Inheritance
  
• Encapsulation
  
• Overriding
  
• Overloading
  
  Other stuff:
  
  
• What happens when you type www.google.com and click enter on the browser
  
• Algorithms Course Heard this is really good
  
  Finally, know Big-O complexity Big-O Cheatsheet! I'm sure there is a lot more but this should be a great start.
  
  Good luck! :)

Elements of Programming Interviews. Personally I found this book more helpful than CtCI as its topics were more focused and relevant to the types of questions I had gotten in technical interviews.

Elements of Programming Interviews.

>Is it worth paying that 65 dollars for those few questions

Why wouldn't you want to do hard problems?

The benefit of algoexpert.io is that the guy walks you through first the concepts (using a digital sketch pad to draw) and then the code itself - the naive solution (if applicable) followed by optimal one. That's the value proposition: maximum hand-holding to learn. I think that's worth $1/question, but your mileage may vary.

As for other advice, if you read this book cover to cover and do every exercise in it you should basically cruise through every coding portion of any technical interview.

0) Entre numa faculdade, qualquer uma. No exterior ninguém conhece nenhuma faculdade brasileira, então tanto faz. Entre num curso para conseguir tirar o visto.

1)Faça esse curso 2 vezes: https://www.edx.org/es/course/introduction-to-computer-science-and-programming-using-python

​

2) Leia e resolva este livro 4 vezes https://www.amazon.com/Elements-Programming-Interviews-Python-Insiders/dp/1537713949/ref=sr_1_1?ie=UTF8&qid=1541552183&sr=8- 1&keywords=elements+of+programming+interviews e resolva 200 problemas aqui www.leetcode.com

​

3) Aplique online ou através de recrutadores em maratonas de programação.

I actually picked up this book in preparation since I'm planning do some interview questions in python pretty soon and I'd say it's well worth it. All the solutions are implemented in python, and it tells you time + space complexity and more optimal possible solutions for the questions. There is an eBook version out there as well.

On Amazon it got good reviews, although I cannot understand why?

The code is literally UNREADABLE, the above code is the first code in Chapter 6, Strings
