Phases Of A Coding Interview
Congratulations, you are ready to put your skills to practice! In a coding interview, you will be given a technical question by the interviewer. You will write the code in a real-time, collaborative editor or on a whiteboard , and have 30 to 45 minutes to solve the problem. This is where the real fun begins!
Your interviewer will be looking to see that you meet the requirements of the role. It is up to you to show them that you have the skills. Initially, it may feel weird to talk while you code, as most programmers do not make a habit of explaining out loud their thoughts while they are typing code.
However, it is hard for the interviewer to know what you are thinking by just looking at your code. If you communicate your approach to the interviewer even before you start to code, you can validate your approach with them. This way, the two of you can agree on an acceptable approach.
Preparing for a remote interview
For phone screens and remote interviews, have a paper and pen or pencil to jot down any notes or diagrams. If you are given a question about trees and graphs, it usually helps if you draw examples of the data structure.
Use earphones. Make sure you are in a quiet environment. You do not want to be holding a phone in one hand and typing with the other. Try to avoid using speakers. If the feedback is bad, communication is made harder. Having to repeat yourself will just result in the loss of valuable time.

Dont Forget The Unasked Question
Most interviewers are so focused on determining your analytical and algorithmic skills, they will often simply forget to ask you the big picture questions about security and performance. If you are applying for a senior technology role, this unasked question should always be proactive answered:
What is the performance trade offs of your solution? If youre working with large data sets, is the performance O, O, O or O? Are there multiple solutions that trade off engineering complexity for performance?
How are you protecting the data? If the dataset contains sensitive or classified material, is the data encrypted at rest? If it is a publicly facing login page, what are the usual techniques to head of a SQL injection attack?
As you are answering your question, feel free to ask for input from the interviewer of what they think so far. If youve gone off track, they will gently guide you back to the answer they are looking for. If you have brought up a discussion topic they had not anticipated, they will appreciate the intellectual diversion.
To sum it up, our interviews are not designed to trip you up. Instead, they are designed to provoke a thoughtful discussion about the pros and cons of various solutions to any given problem. So relax, start sketching on the whiteboard and you will find that just talking through to a solution will put you on the right track.
Skills Necessary To Learn Coding
The revolution in the field of Information Technology has made coding a new literacy. Knowledge of coding has become a basic job requirement in IT industries. Despite the demand, not many know who to code properly. Contrary to what many beginners assume, coding is really fun and easy to learn. One must come out of the notion that coding can be done by mugging up syntaxes. Before you start your first communication with computers through code, you need to possess the following basic skills:
Steve Jobs said, Everyone should know how to program a computer because it teaches you how to think. Learning how to code not only paved the way for a rewarding career but make your brain sharper, smarter and more intuitive.
1. What is the major difference between Coding and Programming?
In the basic terms, Coding relates to the process of writing code or the set of instructions that guides the Computer or an electronic device for performing a specific task. The coder is responsible for translating the human language into compilable and well defined texts. The Programming, on the other hand, has a wider definition and it is associated with all aspects related to creating applications. The terms Programming and Coding tend to be used interchangeably.

Coding Bootcamp Interview Questions
Many aspiring programmers and software developers enroll in coding bootcamps. While coding bootcamps are an excellent way to hone your skills, they often require candidates to complete an interview process before they’re accepted into the program. Whether you’re planning to apply or already preparing for an interview, familiarizing yourself with the questions interviewers often ask during the admissions process can improve your chances of being accepted into a coding bootcamp.
In this article, we share eight common coding bootcamp interview questions, provide examples of how to answer them and list 10 follow-up questions you can ask during your interview to make a good impression.
How Do You Keep Your Technical Industry Knowledge Current
The programming field is constantly evolving, and you can highlight that you enjoy learning new elements and languages to grow.
Example:I enjoy keeping my programming knowledge current and the challenge of learning new languages. I regularly listen to programming podcasts and participate in online communities with other programmers. I also find that online courses are helpful to learn new skills. While I was learning Python, I used podcasts and online courses to study the language while working on a project. I feel these methods work well for me.

Given A Roman Numeral Convert It To An Integer
Cody Daig, technical mentor at Galvanize
What skillset is this testing for? Once you see the solution, it can be very easy to figure out however, getting to that solution is often a struggle for most people. Because you have to think not only about where youre at, but the next value in that Roman numeral. So, for example, four is IV. And so you cant just go, I, thats one, V, thats five boom, were at six! Actually, youre at four. So how do you differentiate between adding and subtracting not only looking at where youre at but where youre going? So its kind of got those two different pieces there.
Is this a good interview question? It depends on the knowledge of the interviewee going into the question here. I make the assumption that most of the time people know Roman numerals, and that can be an incorrect assumption, because not everyone actually knows or understands Roman numerals. So if you are coming into it not even knowing Roman numerals, its a challenging one. In general, I would say youre not at that much more of a disadvantage, as long as youre upfront and honest, like, Hey, Ive never worked with Roman numerals before.
A Simple Guide To Coding Interviews
What most people dont realize is that interviewing is a skill in its own right, one that you can learn and get better at, by studying and practicing. Not only will your knowledge in algorithms and your stack be tested, but also your character, overall knowledge, and your ability to work under pressure.
Ive been in my fair share of interviews, as the interviewer, and the interviewee, and in time I gathered enough experience to know how to land the job, or the contract, and negotiate for the highest salary that I can get. And this is the skill that I hope to pass on to you through this guide.
Most young grads, perceive coding interviews, as this huge monster, standing between them, and their dream job, but know that with enough preparation, you can make this monster your bitch.
Now lets get down to business, Ill break this guide down to 5 sections, Technical questions, Design questions, Behavioral questions, psychological tricks and finally some negotiation tips to make sure you have enough in your bank account to treat yourself every now and then, and maybe buy me a beer if I help you land a job.

About Gayle Laakmann Mcdowell
Gayle is also the founder and CEO of CareerCup.com.
She put together Cracking the Coding Interview for anyone who wants to be prepared when interviewing at a FAANG company.
Cracking the Coding Interview is broken down into two sections:
The Interview Process
- The Facebook Interview
- The Palantir Interview
McDowell gives a detailed rundown of what to expect for each companys recruiting process, how to prepare and what is unique about their interview.
Lets take her Facebook interview as an example.
Interview process: You can expect a phone screen that will involve coding via an online document editor. Then you may have a series of coding and algorithm assignments. Following that, an on-site interview.
No detail is spared in explaining every step of the process.
But note: According to McDowell, Facebook prefers fast, entrepreneurial, and accurate coders. They also interview for non-specific departments. If hired, youll go through their bootcamp for their code base, get mentorship from senior devs, then earn flexibility in your choosing projects.
Can You Tell Me About Your Favorite Project You’ve Worked On So Far
Interviewers may ask this question to learn about your work experience. Highlight a project you worked on that was successful and share what you learned through this process. Then discuss what this project meant to you and why you enjoyed working on it.
Example:”Last year I worked with a team of developers to create an educational app that teaches children how to read with interactive, choose your own adventure e-books. Within the first quarter, we received more than 50,000 user downloads. Working on the app itself was really fun because I got to combine my love for reading with my love for programming.
It also helped me develop my skills using Python, but the reason this project is my favorite is that both parents and children seem to enjoy it so much. Reading their reviews makes me feel good about the work my team did.”

Listen To Every Detail
Coding interviews are interactive so practice your attentive listening! Your active listening reveals the intelligence and inquisitiveness in the interview.
When you listen to a problem, you need to pay attention to all of the details so that you are not off to the races solving the wrong problem. Asking for clarification is encouraged.
What Is Coding In Qualitative Research
Coding is the process of labeling and organizing your qualitative data to identify different themes and the relationships between them.
When coding customer feedback, you assign labels to words or phrases that represent important themes in each response. These labels can be words, phrases, or numbers we recommend using words or short phrases, since theyre easier to remember, skim, and organize.

Google Is Allowed If You Ask
We dont usually tell the candidates that they can Google at the beginning of the coding. We believe the candidate should know the basic syntax and built-in operations of the language they choose.
However, when they are stuck and ask whether they can use Google, we gladly tell them to do so. There is nothing wrong with Googling things you hardly use because we do it every day.
If youre stuck and your solution depends on it, dont be afraid to ask if you can Google. Be honest and only search for the built-in function you have to use, not the entire solution.

Design A Parking Lot Using Object
Cody Daig, Galvanize.
Cody Daig, Galvanize
What skillset is this testing for? Here were looking at, Can you think through how to take something thats not obviously an object at first, and turn it into a series of objects to accomplish what youre trying to accomplish? This will vary a little by language, but ultimately its a class. Its a problem to get you to think through and break down classes.
Sure, you have the parking lot and you have parking spaces. But if we have a programming need for this, we probably need to think through, is a space occupied?That means you have to have the concept of a class of a vehicle, and the vehicle has to occupy a space. You can have the concept of entrances, and parking lots can even have more than one floor. So it really comes down to whether you can take this problem and break it down and think through all of the possible things that need to be considered when building a parking lot.
Is this a good interview question? Its very common to have a question that is vague, but its also acceptable for the interviewee to come back and ask questions. What are you looking for out of this problem? Are we talking a parking lot at Walmart? Are we talking a parking lot with multiple floors? You can ask questions to determine how complex you need to make this. But its a very valid piece for them to just see your thought process and things that you might need to take into consideration.
How To Prepare For Your Phone Interviews
These types of questions arent going to be different from what we have already discussed previously.
But because the purpose of these interviews is to weed out the sub-par candidates in a limited amount of time, expect your interviewer to jump straight into coding questions.
There is no time for lengthy resumes or behavioral questions.
There are a few tips that will help you make the best out of this experience
After your phone interviews, take a deep breath and relax!
It is a waiting game now.
Your recruiter will get back to you in a few days or weeks with general feedback on your performance and the decision they have come to.
If everything went well, then your recruiter will congratulate you and schedule some time for your next big milestone.
Your on-site interviews!
On-site interviews are fundamentally different from phone interviews.
I personally like on-site interviews more.
I mean I like to be interviewed face to face rather than be interviewed on the phone.
It is just easier to communicate with your interviewer face to face and it makes the whole process much simpler.

What Types Of Coders Are There
To fully understand the coding background, you need to know that there is a wide range of different types of coders out there. Each of them specializes in a different thing, and each of them is required to learn different languages and techniques that allow them to specialize in these things.
Although we have explained what is coding and three of the most common types of coders below, there are many, many more. Some of the other types not touched on include systems engineers, game developers, and AI programmers – among others.
Know Your Type Of Coding Interview
Coding interviews could follow many different formats. For example, your interview might focus on answering questions or using a whiteboard to write information down for the hiring manager. In other cases, you may have completed a coding test before the interview, allowing the hiring manager to focus more on your work process and ability to fit in with the company culture.
Find out what interview type you’ll have before you begin practicing to divide your time wisely. Consider contacting the company directly and asking them what kind of interview to expect.
