Learn how to explore a grid and find a goal point with breadth first search in this pathfinding tutorial. You will use Processing and Java to code the breadth first search pathfinding algorithm and create a graphical demo so you can see it in action.

In the last tutorial, we programmed depth first search and watched it explore a node graph. In this tutorial we will program breadth first search and watch it explore a grid.

The breadth first search algorithm will add every unexplored adjacent node to a queue, and explore all of the added nodes in sequence. For each node explored, it will continue to add the adjacent unexplored nodes to the queue. It will continue to do this until the goal is found or all connected nodes have been explored.

How to Prepare for a Coding Interview

Coding interviews are a crucial part of the tech hiring process. As a candidate, you'll need to showcase your technical skills, problem-solving abilities, and understanding of data structures and algorithms. To succeed, it's essential to be well-prepared. In this article, we'll discuss the steps you can take to prepare effectively and increase your chances of getting hired.

Understanding the Coding Interview Process

Before diving into the preparation, it's important to understand the coding interview process. 

These interviews are not just about writing code; they also test your ability to think critically under pressure and explain your reasoning behind the solutions you propose. Interviewers are interested in understanding your approach to problem solving and how you handle challenges in a real-time setting.

The Role of Coding Interviews in Tech Hiring for Candidates

By evaluating your coding abilities, interviewers can determine if you're the right fit for the job and the company culture. However, it's not just a one-sided test. It's also an opportunity for the candidate to learn more about the company and its work environment.

Developers will only be successful in a role if the environment is one that is conducive to how they like to work, collaborate, and engage. It’s a win-win benefit for both candidates and employers if both sides are equally excited at the prospect of working together.

Different Types of Coding Interviews

Coding interviews can vary in format and structure. Some companies may conduct coding interviews in-person, while others prefer remote interviews. Additionally, coding interviews can be divided into different types, such as whiteboard coding exercises, take-home assignments, or pair programming sessions.

Each type of coding interview has its own unique challenges and requirements. Whiteboard coding exercises, for example, test your ability to write code on a whiteboard while explaining your thought process out loud. 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. These platforms often offer interactive coding challenges, enabling you to practice solving problems under time constraints. Engage in coding competitions or take part in mock interviews to get a real feel for the interview process.

Brush Up on Technical Knowledge

Aside from coding skills, brush up on your technical knowledge. Review key concepts related to your preferred programming language, data structures, algorithms, and system design. Understanding these concepts in-depth will help you during technical discussions and coding challenges.

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.

In Conclusion

Preparing for a coding interview requires a combination of technical skills, problem-solving abilities, and effective communication. Understanding the coding interview process, mastering essential skills, and thorough preparation will increase your chances of getting hired. Remember, practice makes perfect, so devote enough time to solving coding problems, reviewing concepts, and gaining confidence.

"Fuck, fuck, fuck.” Mia shouted angrily, grabbing some clothing she found laying on the floor. She couldn’t be fussy this morning, she had to wear whatever she just picked up - after all, she was running late for work. The brown haired woman couldn’t exactly be late for work either as she had to hand over her presentation to her boss before the children came in. Mia questioned why she wanted to work as a teacher when all she truly wanted in that moment in time was more sleep. “Coffee.” She blurted out to herself, shrugging on her backpack. The brunette looked in the mirror, she really looked like a school kid. She was wearing a jumper, leggings, boots and a backpack with her hair tied in a bun. Mia always worried the children wouldn’t take her seriously if they had her in class and she felt as though her attire wasn’t helping her case either. Mia ran out the door, locking her apartment after her.

Mia was currently on one mission - get coffee. The short woman ran down the streets, trying her best to make it in time for coffee and work - she couldn’t do her job this tired after all. The brunette wasn’t usually one for coffee either, she was truly a tea lover through and through. Although, she did know when she was needing it - it just meant that she would be up all night marking papers before crashing hard. “Coffee, coffee, coffee.” The girl murmured, looking up at the shop that stood before her - Java Junction. She sped in, not realising she had jumped the queue. “Can I get a triple-shot espresso iced coffee please?” She asked the server, pulling out her phone from her bag to pay. The brunette looked up at the server with a puzzled face before turning round to the person before her who was also about to pay for their items. “Oh my God, I am so sorry.” She blurted out, looking the person up and down. “I just jumped didn’t I? I’m like the worst person ever. Please let me buy you your stuff.”
