Whether you're a beginner or looking to strengthen your existing knowledge, a well-structured course can help you unlock your full coding potential.

Apparently it's a month of code or something because my dash is filled with people trying to learn Python. And that's great, because Python is a good language with a lot of support and job opportunities. I've just got some scattered thoughts that I thought I'd write down.

Python abstracts a number of useful concepts. It makes it easier to use, but it also means that if you don't understand the concepts then things might go wrong in ways you didn't expect. Memory management and pointer logic is so damn annoying, but you need to understand them. I learned these concepts by learning C++, hopefully there's an easier way these days.

Data structures and algorithms are the bread and butter of any real work (and they're pretty much all that come up in interviews) and they're language agnostic. If you don't know how to traverse a linked list, how to use recursion, what a hash map is for, etc. then you don't really know how to program. You'll pretty much never need to implement any of them from scratch, but you should know when to use them; think of them like building blocks in a Lego set.

Learning a new language is a hell of a lot easier after your first one. Going from Python to Java is mostly just syntax differences. Even "harder" languages like C++ mostly just mean more boilerplate while doing the same things. Learning a new spoken language in is hard, but learning a new programming language is generally closer to learning some new slang or a new accent. Lists in Python are called Vectors in C++, just like how french fries are called chips in London. If you know all the underlying concepts that are common to most programming languages then it's not a huge jump to a new one, at least if you're only doing all the most common stuff. (You will get tripped up by some of the minor differences though. Popping an item off of a stack in Python returns the element, but in Java it returns nothing. You have to read it with Top first. Definitely had a program fail due to that issue).

The above is not true for new paradigms. Python, C++ and Java are all iterative languages. You move to something functional like Haskell and you need a completely different way of thinking. Javascript (not in any way related to Java) has callbacks and I still don't quite have a good handle on them. Hardware languages like VHDL are all synchronous; every line of code in a program runs at the same time! That's a new way of thinking.

Python is stereotyped as a scripting language good only for glue programming or prototypes. It's excellent at those, but I've worked at a number of (successful) startups that all were Python on the backend. Python is robust enough and fast enough to be used for basically anything at this point, except maybe for embedded programming. If you do need the fastest speed possible then you can still drop in some raw C++ for the places you need it (one place I worked at had one very important piece of code in C++ because even milliseconds mattered there, but everything else was Python). The speed differences between Python and C++ are so much smaller these days that you only need them at the scale of the really big companies. It makes sense for Google to use C++ (and they use their own version of it to boot), but any company with less than 100 engineers is probably better off with Python in almost all cases. Honestly thought the best programming language is the one you like, and the one that you're good at.

Design patterns mostly don't matter. They really were only created to make up for language failures of C++; in the original design patterns book 17 of the 23 patterns were just core features of other contemporary languages like LISP. C++ was just really popular while also being kinda bad, so they were necessary. I don't think I've ever once thought about consciously using a design pattern since even before I graduated. Object oriented design is mostly in the same place. You'll use classes because it's a useful way to structure things but multiple inheritance and polymorphism and all the other terms you've learned really don't come into play too often and when they do you use the simplest possible form of them. Code should be simple and easy to understand so make it as simple as possible. As far as inheritance the most I'm willing to do is to have a class with abstract functions (i.e. classes where some functions are empty but are expected to be filled out by the child class) but even then there are usually good alternatives to this.

Related to the above: simple is best. Simple is elegant. If you solve a problem with 4000 lines of code using a bunch of esoteric data structures and language quirks, but someone else did it in 10 then I'll pick the 10. On the other hand a one liner function that requires a lot of unpacking, like a Python function with a bunch of nested lambdas, might be easier to read if you split it up a bit more. Time to read and understand the code is the most important metric, more important than runtime or memory use. You can optimize for the other two later if you have to, but simple has to prevail for the first pass otherwise it's going to be hard for other people to understand. In fact, it'll be hard for you to understand too when you come back to it 3 months later without any context.

Note that I've cut a few things for simplicity. For example: VHDL doesn't quite require every line to run at the same time, but it's still a major paradigm of the language that isn't present in most other languages.

Take-home assignments, on the other hand, give you the opportunity to work on a coding problem at your own pace and showcase your problem-solving skills in a more relaxed environment. Pair programming sessions involve collaborating with an interviewer to solve a problem together, demonstrating your ability to work effectively in a team setting.

Essential Skills for Coding Interviews

Preparing for a coding interview requires mastering several essential skills. Let's explore these skills in detail.

Programming Languages to Master

Individuals should be proficient  in at least one programming language commonly used in the industry, such as Python, Java, C++, or JavaScript. Understanding the syntax, data types, control structures, and libraries of your chosen language will help you solve coding problems efficiently.

Problem-Solving Skills

Problem-solving skills are an integral part of a coding interview. Being able to approach a problem strategically, break it down into smaller subproblems, and devise an efficient solution is highly valued. Practice solving coding challenges and algorithms to sharpen your problem-solving abilities.

Understanding Data Structures and Algorithms

Data structures and algorithms are the building blocks of computer science. Familiarize yourself with various data structures like arrays, linked lists, stacks, queues, trees, and graphs. Additionally, learn popular algorithms for searching, sorting, and optimization. Understanding these concepts will help you analyze problems and devise optimal solutions.

Pre-Interview Preparation

Embarking on the journey of pre-interview preparation is akin to laying the foundation for a successful career in the tech industry. The diligence and effort you put into honing your skills now will pave the way for future opportunities and growth. Here are a few steps you should take before the interview.

Review Common Coding Questions

Start by researching and reviewing common coding questions asked in interviews. Online platforms like LeetCode or HackerRank offer a vast collection of coding problems categorized by difficulty levels. Spend time solving these problems to familiarize yourself with the question patterns and potential solutions.

Practice on Coding Platforms

Practicing on coding platforms simulates the interview environment and helps improve your coding skills.

During the Interview

Now let's focus on what to do during the coding interview to maximize your chances of getting hired.

When you enter the interview room, remember that your body language and demeanor also play a significant role in making a positive impression. A firm handshake, good posture, and maintaining eye contact can convey confidence and professionalism. These non-verbal cues can complement your technical skills and create a well-rounded image for the interviewer.

Effective Communication During Coding Interviews

During the interview, effective communication is crucial. Clearly explain your thought process, rationale, and any assumptions you make while solving a problem. Communicating effectively helps the interviewer understand your approach and evaluate your problem-solving abilities.

Moreover, active listening is equally important during coding interviews. Pay close attention to the interviewer's prompts and questions. This demonstrates your ability to process information in real time and adapt your problem-solving strategy accordingly. Engaging in a dialogue rather than a monologue can showcase your collaborative skills and willingness to take feedback.

Demonstrating Your Thought Process

Interviewers are interested in how you approach problems and arrive at solutions, rather than just the end result. Be vocal about your thought process throughout the interview. Explain the steps you're taking, potential optimizations or trade-offs, and any ideas that come to mind. This demonstrates your ability to analyze problems and think critically.

Also, don't hesitate to ask clarifying questions if you encounter ambiguity in the problem statement. Seeking clarification shows your attention to detail and ensures that you and the interviewer are on the same page. It's better to take a moment to clarify the problem than to proceed with a misunderstanding that could lead you down the wrong path.

Handling Unknown Problems

Not all problems presented in coding interviews are familiar or straightforward. Interviewers often assess candidates' ability to handle unknown problems and think on their feet. When faced with unfamiliar problems, stay calm and logical. Break down the problem, identify patterns or similarities to other problems you've solved, and come up with a step-by-step approach.

Remember, the interviewer is not just evaluating your technical skills but also your problem-solving methodology. Demonstrating resilience in the face of uncertainty and showcasing adaptability can leave a lasting impression. Embrace the challenge of unknown problems as an opportunity to showcase your creativity and resourcefulness in problem solving.
