    There’s no doubt about it: coding interviews are stressful. But you don’t have to worry! We’re here to help. In the following sections, we’ll walk through everything you need to know about preparing for your coding interview in 10 steps.

    Prepare for the questions

    The first step to preparing for your coding interview is knowing what kind of questions you will be asked. There are many different types of questions, from simple logic puzzles to complex algorithms. You can find lists of common interview questions online or even practice with friends who are also interviewing for jobs at tech companies.

    You should also think about how to best prepare yourself for each type of question so that when it comes time for the actual interview, nothing will surprise you–and even better: You’ll know exactly how long it will take to solve each problem!

    Practice your coding skills and get feedback

    Once you’ve learned the fundamentals of programming and data structures, it’s time to practice what you’ve learned. The best way to do this is by writing programs in an IDE (integrated development environment) like Visual Studio or Eclipse Code*Blocks*.

    You can also use online tools like Codewars and HackerRank that allow you to solve problems in several different languages (Python, Ruby etc). If you want something more freeform but still helpful for practicing syntax and getting used to working on a whiteboard with pen or pencil then check out CodeWars where users post their solutions in Jupyter Notebooks which are interactive javascript files that let you run code directly from within them

    Learn about the company you are interviewing for

    Once you have a date for your interview, it’s time to start preparing. The first thing that you should do is research the company and its culture. You can find this information on the company’s website or LinkedIn profile, but it’s also helpful if people who work there give you tips about what it was like when they were hired and what they like about working there.

    Once you know what type of work the company does and how long they’ve been doing it (as well as whether they’re expanding), ask yourself: Is this something I want to be part of? If so, why? What makes them unique? How will my skills fit in with their needs?

    Find a way to practice with a whiteboard and pen or pencil

    Practice with a whiteboard and pen or pencil. This can be done by yourself, but it’s more fun to do with friends. If you don’t have access to a whiteboard, try using paper (you might want colored pens).

    Practice on your own computer if possible — this will help you get used to writing code in front of other people without feeling self-conscious about what’s showing up onscreen!

    Another option is online quizzes like InterviewCake, CodeFights or CodinGame where there is no time pressure and lots of room for experimentation.

    Ask about the company’s culture and values

    If you’re interviewing for a position at a company, you should ask about the culture. How does the team work together? What are their values? Are there any specific traits that they look for in potential employees?

    If you’re interviewing with a company that has an open-source project or two under its belt (and if not, why not?), then it’s even more important to know what they do and don’t value. The best way to learn this is by looking at their GitHub repositories: You can see how often they commit code; whether or not they use feature branches; if they follow industry standards (like Semantic Versioning); and other signs of good engineering practices.

    Meet the team you’ll be working with

    You will be spending a lot of time with them, so it’s important to know if you can get along and work well together.

    You can prepare for your coding interview in 10 steps, but it will take some time.

    To prepare for your coding interview, you can follow these 10 steps:

    • Find out what tools and languages are used in the company you’re applying to. Make sure that your programming skills are up-to-date and relevant to what they need. If possible, try out some of the tools on their website or Github page (if they have one). This will give you an idea of whether or not it’s something you want to learn in order to get hired there!
    • Practice writing code on paper before going into the interview room so that when it comes time for questions about algorithms or data structures, etc., there won’t be any surprises about whether or not these concepts make sense at least at a high level; this way when asked questions like “How would we go about finding an element in an array?” We won’t freeze up because we weren’t expecting such specific technical question types!

    I hope this article has given you a better idea of how to prepare for your coding interview. I know that it can seem overwhelming, but remember: there’s no such thing as perfect preparation. The key is just to do the best you can and keep practicing until you feel confident in your skills.


    how to prepare for coding interview: How To Prepare for Your Coding Interview in 10 Steps


    The process of preparing for a coding interview can be intimidating, especially if you don’t know what to expect. But before we dive into how to prepare for your upcoming interview, let’s look at some things that are essential to understand before you start practicing:

    1. Set a goal and plan your study

    The first thing you need to do is set a goal and plan your study. This can be difficult because there are so many resources available on the internet, but you have to find what works for you.

    The most important thing is understanding the format of the interview, which will vary from company to company and even from role-to-role within one company. You want to practice answering questions in this format before going into an actual interview so that when it comes time for real life, nothing feels foreign or unfamiliar.

    Another good idea would be finding someone who has been through this process before–a role model or mentor–and asking them questions about their experience: what worked well; what didn’t work so well; things they wish they knew beforehand… The more information about how these things work in advance means less stress during actual interviews!

    2. Understand the format of the interview

    The next step is to understand the format of your interview. You should be prepared for a coding interview that lasts anywhere from 30 minutes to an hour and a half. Some companies may even have multiple rounds of interviews, so it’s important to know how long each will take and what you have coming up next if you are interviewing with multiple companies in one day.

    Also, be sure to know what type of environment you’ll be interviewing in: whether it’s a quiet room or loud coffee shop; whether there will be other people around; whether they’ll ask questions directly or via Piazza (a discussion board used by many tech companies); etcetera!

    3. Find a role model or mentor who has been through the process before

    • Find a role model or mentor who has been through the process before

    Find someone who has been through the process before, and ask them for advice. Ask them to help you prepare for the interview.

    4. Build a strong resume that shows off your relevant experience, education, and unique skills

    • Make sure your resume is up to date.
    • Include relevant experience, education, and unique skills.
    • Use a professional resume format.
    • Use a resume template or builder tool if you’re not sure how to write one yourself (or just want some help).
    • Use a service like ResumeGo or Resumonk if you don’t have time to do it yourself or aren’t confident in your writing abilities yet!

    5. Study for the technical skills of the job you’re applying for

    The first step to preparing for your coding interview is to learn the basics of the language. You should be able to write a simple program in this language, and understand how it works. You don’t need to be an expert; just enough so that you can read other people’s code and understand what they’re doing!

    Next, learn how to use libraries and frameworks: what are they, why do we use them? This is important because most projects rely heavily on some external library (for example React Native). If your interviewer asks about using a specific library/framework in their project, then knowing how it works will help greatly with answering questions correctly.

    Finally–and this is probably one of the most important parts–learn how testing works in whatever language(s) you’re learning about! Having good test coverage means fewer bugs after deployment; being able to write effective tests early makes development faster later on down the line too because there won’t be as much manual QA needed before pushing new code onto production servers

    6. Focus on learning about the company where you want to work

    It’s important to know more about the company you want to work for, especially if it’s your dream company. This will help you prepare for an interview by giving you more information about what they do and how they work.

    You should learn:

    • The company culture – How do people behave? What are their values? Are there any unique perks or traditions that make this place unique compared with others in its sector/industry space (for example, Google has a slide!)? If possible, read interviews from former employees who left on good terms so as not only get feedback but also hear from someone who knows what life there is like firsthand!
    • Company history – Who founded it and why did they start this business? What has been achieved over recent years; how has growth been managed so far; what plans do they have for future expansion (if any)?

    7. Practice making it through an entire interview process from start to finish at least once, if possible

    The final step in preparing for your coding interview is to practice the entire process from start to finish, if possible. This will help you get used to the flow of an interview and make sure that everything goes smoothly on the day.

    If you’re not able to practice with a real recruiter or hiring manager, then try doing this with friends or family members who can play those roles instead–they’ll be happy to help!

    8. Know how to answer any question no matter what it is — even if they don’t ask it directly!

    You should be prepared for any question, no matter what it is. This means you need to have a solid understanding of your strengths and weaknesses, as well as the answers to questions about your work history and education. You also need to be flexible enough in order to answer questions about your interests or hobbies outside of work–the interviewer wants to see how well rounded you are!

    If you’re asked a question that doesn’t pertain directly with coding or data science (or whatever field they’re hiring for), don’t panic! Think through all possible angles before giving an answer–do some research on Google if necessary–and try not make assumptions about what they want from their answers; instead focus on providing clear details about why something could work well/poorly depending on certain factors such as time constraints or budget constraints etcetera…

    9. Prepare for behavioral questions and practice answering them under pressure in a mock interview setting using practice coding questions that mimic real ones! (example –

    • Prepare for behavioral questions and practice answering them under pressure in a mock interview setting using practice coding questions that mimic real ones! (example –
    • Know your resume inside and out. You’re going to be asked about it, so make sure you know how to explain every line item on your CV in detail!
    • Practice the interview process from start to finish at least once before your actual interview day arrives. This will help ensure that there are no surprises when it comes time for real world testing!
    • Have a plan for the day of the interview: what time do I need to leave for my Lyft or Uber ride? Where should I park at this location? Is there anything else important about getting into this building or arriving at said location that I should know beforehand?
