Best Programming Language For Coding Interviews

List Of Reading Lists

Jeff Atwood of Coding Horror fame published this list of recommended reading.

Jeff’s selections, especially compared to Steve Yegge’s below, are more focused on UI and usability than software patterns and algorithms. In his own words,

“It’s really a question of focus. I’m more interested in UI and usability.”

Especially if you are looking at positions in web development, product management, front-end development or project management, use Jeff’s books to branch out and learning a bit about topics outside of what’s considered “core” computer science.

Jeff’s selections give you a dangerous skillset. Anyone who has consumed all of these books should not have trouble finding or creating work for the rest of their life.

Job Opportunities In Javascript

If you want to be a front-end developer, you need to know JavaScript very well. However, JavaScript-based careers arent limited to only client-side programming. Full-stack development, data science, AI and machine learning, gaming, and information security benefit from JavaScript expertise. There are about 445,000 jobs advertised on Indeed and approximately on LinkedIn in the United States alone.

Is there a purpose to learning JavaScript?

• In terms of versatility, JavaScript is one of the best. Its utilized in AngularJS and NodeJS scripting, respectively, on the client and server.
• As a novice, JavaScript offers you skills that will help you learn Python, C++, and Java more quickly. It supports various programming paradigms, including object-oriented, imperative, and functional.
• Due to its asynchronous programming model, JavaScript is both interoperable and very fast when used for client-side scripting.

Struggles

• JavaScript is not as effective for cross-browser development since browsers read it differently.
• JavaScript doesnt provide client-side security for malicious reasons.

How Would You Implement The Insertion Sort Algorithm

• We assume the first element in the array to be sorted. The second element is stored separately in the key. This sorts the first two elements. You can then take the third element and do a comparison with the ones on the left of it. This process will go on until a point where we sort the array.

int a =

for {

int n = m

while {

int k = a

a = a

a = k

How To Create High

1. Cover as many survey responses as possible.

The code should be generic enough to apply to multiple comments, but specific enough to be useful in your analysis. For example, Product is a broad code that will cover a variety of responses but its also pretty vague. What about the product? On the other hand, Product stops working after using it for 3 hours is very specific and probably wont apply to many responses. Poor product quality or short product lifespan might be a happy medium.

2. Avoid commonalities.

Having similar codes is okay as long as they serve different purposes. Customer service and Product are different enough from one another, while Customer service and Customer support may have subtle differences but should likely be combined into one code.

3. Capture the positive and the negative.

Try to create codes that contrast with each other to track both the positive and negative elements of a topic separately. For example, Useful product features and Unnecessary product features would be two different codes to capture two different themes.

4. Reduce data to a point.

Lets look at the two extremes: There are as many codes as there are responses, or each code applies to every single response. In both cases, the coding exercise is pointless you dont learn anything new about your data or your customers. To make your analysis as useful as possible, try to find a balance between having too many and too few codes.

Are You Interviewing For A Language

If youre trying out for a rock band, you shouldnt sing opera during your audition. Your ultimate purpose in an audition is to show that you would be a good member of the band. Even if youre a great singer, unless the band has a need for someone to sing opera they dont really have any idea whether you will sound good singing rock. In the same way, why would someone want to hire you as an Android developer if all they know about you is that you are good at Ruby?

If the job youre applying to is language-specific, this makes choosing a language for your interview really easy. Interview in the language youre going to be using for your job.

The best way to show off your value to the company is to show them that you are good at what you will be working on. Be sure to know the language intimately and be prepared for language-specific interview questions, since these are all fair game during your interview.

While it is important to use the right language if youre interviewing for a language-specific job, many positions are more general, particularly for new grads. While these positions may use one primary language, there is little expectation that you will be very knowledgeable when you start and the plan is often for you to receive some training. If youre applying for a job like this, your next question is:

Best For Abstract Problems: Grokking The Coding Interview

Grokking the Coding Interview is a course that gives you the ability to map a new problem to an already known problem. Throughout the course, you will learn 16 different patterns for coding questions, based on the similarities in the techniques needed to solve them. The idea behind this concept is that once you are familiar with one of the patterns, you’ll be able to solve dozens of problems with it. This is helpful because, during the real technical interview, you will most definitely be getting a question you have never seen before. Being able to apply your knowledge and work through these abstract problems with little to no detail is what will get you through the coding interview. This resource is better than other books like programming interviews exposed and programming pearls because it gets right to the point. Grokking is a great resource for people just starting out.

How Easy Is It To Solve Algorithmic Problems In The Language

Some languages are better for different things. You wouldnt use C++ for your website, and you wouldnt use Javascript for statistical analysis. In the same way, some languages are better for interviews.

Since different languages have different built in types and different paradigms, the language you choose can drastically change not only how you solve the problem, but what problems you get asked.

For example, popular problems in Java involve modifying linked lists. However, in Python lists are a built in datatype, so those problems dont make a whole lot of sense. While you certainly could implement a list manually, why would you?

Ultimately, this is very much secondary to choosing your strongest language, but if youre struggling to decide, choose the one that will make your life easier. Many people prefer Python for this reason.

However, it isnt only about your ability to write code, but your interviewers ability to understand the code you write, so before committing to a language, ask:

Study Common Interview Concepts

A large percentage of interview questions feature data structures and algorithms. For better or worse, this is the truth. We gather question details from our candidates who interview at companies , and algorithm questions make up over 70% of the questions that are asked. You do not need to be an expert, but knowing the following list of algorithms and data structures will help at most companies.

• Dynamic programming
• Big-O analysis

Depending on your background, this list may look trivial, or may look totally intimidating. Thatâs exactly the point. These are concepts that are far more common in interviews than they are in production web programming. If youâre self-taught or years out of school and these concepts are not familiar to you, you will do better in interviews if you study them. Even if you do know these things, refreshing your knowledge will help. A startlingly high percentage of interview questions reduce to breadth-first search or the use of a hash table to count uniques. You need to be able to write a BFS cold, and you need to understand how a hash table is implemented.

Studying algorithms and data structures helps not only because the material comes up in interviews, but also because the approach to problems taken in an algorithm course is the same approach that works best in interviews. Studying algorithms will get you in an interview mindset.

Picking A Programming Language

Before anything else, you need to pick a programming language for your algorithmic coding interview.

Most companies will allow you to code in the language of your choice. The only exception I know is Google. They allow their candidates to pick from only Java, C++, Python, Go or JavaScript.

For the most part, I recommend using a language that you are extremely familiar with, rather than one that is new to you but that the company uses widely.

There are some languages that are more suitable than others for coding interviews. Then there are some that you absolutely want to avoid.

From my experience as an interviewer, most candidates pick Python or Java. Other languages commonly selected include JavaScript, Ruby, and C++. I would absolutely avoid lower-level languages like C or Go, simply because they lack standard library functions and data structures.

Personally, Python is my de facto choice for coding algorithms during interviews. It is succinct and has a huge library of functions and data structures.

One of the top reasons I recommend Python is that it uses consistent APIs that operate on different data structures, such as len, for … in … and slicing notation on sequences . Getting the last element in a sequence is arr , and reversing it is simply arr. You can achieve a lot with minimal syntax in Python.

Python Is Simple To Learn

One reason why Python is so great for coding interviews is because of its simplicity. If you have programming experience in any other language, Python will be very easy to pick it. Especially if you have coded in C, C++, or another object-oriented programming language.

If you havent coded before, Python is also a great first choice.

Choosing a language that is easy to use syntactically is important. The algorithms and data structure challenges that will be provided will be challenging enough. You dont want to make your life harder than it needs to be by choosing a difficult language to use.

I first learned Python a few years back when I took an online course in computer science fundamentals and was able to quickly pick up the language in about a week. If I were to start over again today, I could probably learn it in a day. So dont let the learning curve stop you from picking up Python! It is always great to have multiple languages on your resume anyway.

If you are new to Python and need a learning resource, this is a great place to start.

What To Do When You Get The Question

Many candidates start coding as soon as they hear the question. That is usually a big mistake. First, take a moment and repeat the question back to the interviewer to make sure that you understand the question. If you misunderstand the question, then the interviewer can clarify.

Always seek clarification about the question upon hearing it, even if you think it is clear. You might discover that you have missed something. It also lets the interviewer know that you are attentive to details.

Consider asking the following questions.

• How big is the size of the input?
• How big is the range of values?
• What kind of values are there? Are there negative numbers? Floating points? Will there be empty inputs?
• Are there duplicates within the input?
• What are some extreme cases of the input?
• How is the input stored? If you are given a dictionary of words, is it a list of strings or a trie?

After you have sufficiently clarified the scope and intention of the problem, explain your high-level approach to the interviewer, even if it is a naive solution. If you are stuck, consider various approaches and explain out loud why it may or may not work. Sometimes your interviewer might drop hints and lead you toward the right path.

Only start coding after you and your interviewer have agreed on an approach and you have been given the green light.
