Interview-Prep

Gearing up for interviews? This repository aims to hold all the resources needed to crush your next interview!

At the time of creating this guide, I am a current student in the Front End program at the Turing School of Software and Design. In an effort to prepare for my first software job search, I've decided to make one giant resource for myself to get ready.

While this resource will constantly be expanding over the next couple of months, feel free to fork it and use it for your own upcoming interview prep, or Click ⭐ if you like the project!

Behavioral Questions

Many companies want to get to know YOU. Make sure that your answers reflect who you are as a person. If you are a career changer, sometimes it can help to share why you've made the switch to this new industry!

  1. Tell me about yourself
  • This'll be your elevator pitch!
  1. What are your weaknesses? What are your strengths?
  • For both of these, make sure to highlight how you work to overcome your weakness, or how your strength can play a part in the organization!
  1. Why do you want to be a software developer?
  2. Tell me about a challenging interaction with a teammate
  3. Tell me about a project you've completed that you're proud of
  4. Tell me about a problem you faced and how you solved it
  5. Tell me about a time you were under pressure- how did you handle it?
  6. What motivates you?
  7. What is the most helpful feedback you've ever received about yourself?

  21. What is your approach to working on a team?
  22. What is something that your hobbies or interests tell me about you that your resume cannot?
  23. Sometimes it’s just not possible to get everything on your to-do list done. Tell me about a time your responsibilities got a little overwhelming. What did you do?
  24. Describe a time when you saw some problem and took the initiative to correct it rather than waiting for someone else to do it
  25. Tell me about a time you needed to get information from someone who wasn’t very responsive. What did you do?
  26. Imagine you're tasked with organizing a team bonding offsite activity. Some teammates have expressed concerns about the selected activity not being inclusive enough. What kind of actions can you take to ensure that every member of the team feels included, and how can you follow up with your teammates who have expressed concerns?

Technical Challenges

Here are some short, simple technical challenges to get started. Consider talking through how you would approach these problems, and then try them for yourself in your console (you'll need to write test cases).

  1. Is Unique Implement an algorithm to determine if a string has all unique characters.
  2. URLify Write a method to replace all spaces in a string with "%20".
  3. Is Prime Write a method to determine if an int n is a Prime number.
  4. There are n kids with candies. You are given an integer array candies, where each candies[i] represents the number of candies the ith kid has, and an integer extraCandies, denoting the number of extra candies that you have. Return a boolean array result of length n, where result[i] is true if, after giving the ith kid all the extraCandies, they will have the greatest number of candies among all the kids, or false otherwise.
  5. Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order.

Coding Challenge Resources

There are plenty of coding challenge resources on the web that will help you work through problems that you might see in a technical interview challenge. Here are just a few!

  • Leetcode
    • Many interviews will have "leetcode-esque" type questions. It could be helpful to get used to seeing problems written out in this structure.
  • Codewars
  • Codesignal
    • Similar to leetcode in structure, practice tests refresh every 24 hours. There is also an arcade mode where you can test your skills. -Codeforces
    • Div 2 and Div 3 questions A,B should be reasonable (under contests => contest history)
    • Requires command line processing -Kattis, Kattis
    • Requires command line processing
  • Problem Solving Techniques for Programming Problems and Interviews
  • Project Euler -These can be quite mathy, but the first few 10 or so problems will be helpful if you can recognize the patterns
  • Advent of Code - The first couple days of problems are really good practice and should be manageable to solve (you can look at previous year's problems too)
  • CodingJS -Pretty straightforward problems that are broken down into data types, really helpful!

Algorithm Resources

Having an understanding of algorithms and data structures could make your interviewing process much easier, and will help you in the long run during your programming career. Often programming challenges will be based upon a simple algorithm, and being able to recognize which algorithm can be used will save you time during your interview.

BigO Resources

Big O describes the performance or time complexity of a program (that is, the execution time required or space used to run your algorithm). Many technical questions will be bound by a certain limitations in regards to how quickly or efficiently your solution needs to run.
