Best Tips And Strategies To Prepare For A Coding Interview

Preparation for acing a coding interview starts months before the interview itself. You will have to get the right experience, build projects outside of school, find internships, do mini-projects to solidify your understanding of key concepts, practice explaining code, and a lot more things. We know that its hard to prepare for tech interviews, and we all need some guidance to start preparing in the right direction. To resolve this problem and clear your doubts in this article, we are going to talk about some points which are going to help you tackle the coding interview preparation process effectively. Below are some basic things that a person need to get a job in an IT company

1. Creating a Good Resume: Creating a good resume means your resume should be able to pass the initial screening of an applicant tracking system that is programmed to match keywords from the job description. Your resume should contain only information which is relevant to the job description and that too should be highlighted as the recruiter will go through your resume for few seconds. For example put the job title of the job description right under your name at the top so that ATS ranks your resume higher and the recruiter can immediately observe it.

Create a cover letter that tells about common problems in your industry, and how youve solved that problem in the past. Tell them why you want to work with them by expressing your excitement, and thank them for reading your letter.

Prepare Questions To Ask The Interviewer:

At the end of every interview, the interviewer will ask the candidate to ask any doubts regarding the interview process as a form of feedback. Many people usually ignore this aspect, but asking a good question can do you wonders for the interview. Try spending some time in researching good questions, as it can be a chance to impress your interviewer.

There is no clear distinction between good or bad questions. Also, asking such questions will give the interviewer how much you are keeping up with the present time and technology. Also, if you do not find anything suitable to ask, you could ask simple questions based on the technology used, infrastructure and other formalities of the company. Also, do not ask any feedback regarding your performance in the interview.

Know The Company And The Interviewer

Do your research on the company. Find out what technologies and frameworks they use. What are their five year initiatives? What markets and domains do they work with? Research gives you not only good talking points and shows your interest in the company, but also helps you pinpoint where your skills align with the job requirements.

While researching the company, look up your interviewer on LinkedIn. Knowing a little bit about this individual can help you tailor your answers in a way the interviewer will best understand. For example, an HR director may not understand technical jargon whereas a lead software engineer would welcome it. Lastly, know the interviewers name and use it somewhere in the interview. Remember that youre speaking to another human being, and using someones name shows respect and expresses interest in possibly working with this person.

Learn A Consistent Method

The problems you can expect to face in your coding interview are highly ambiguous and can usually be solved many different ways.

To guide and structure your thinking, youll therefore want to use a consistent answer framework that you can apply to each question.

One of our favorite approaches is summarized in the following video from Amazon:

Here is a summary of the approach:

Five step approach to coding interview problems

    Using this framework will give you a structure which you can use to show your problem-solving skills and, of course, your coding knowledge, which well move on to now.

    Data Structures & Algorithms

    Honestly, these are foundational to everything that we do in coding interviews. Trying to do a coding interview without having your data structures and algorithms down would be like trying to play a game of basketball without knowing how to dribble. No amount of strategy is going to help you when you can’t move the ball down the court.

    Since you don’t have a lot of time here, you need to be very focused in your approach. You definitely don’t have time to study everything so you want to focus on the few things that are going to give you the most bang for their buck. I’d focus on the following: Trees, Graphs, Recursion, and Strings & Arrays.

    Obviously this isn’t everything, but you don’t have a lot of time here, so I’d spend the first 2 days of my 1 week on these and really getting them dialed in.

When a hiring manager wants to learn about your thought process, they might ask you to explain concepts. Before your interview, explain complex coding topics out loud to a friend.

    Tip #: Stay Optimistic But Prepare For Challenges

    Best FREE site for coding interviews

    If youre the luckiest developer on the planet, you might be able to sail through your first interview and land a job right away but for most people, the process takes a bit longer.

    According to Hireds research, candidates with four to six years of experience field an average of 7.7 interview requests before landing a job. For some, it can take even longer a cursory internet search reveals countless stories of beleaguered coders who interviewed at 30 or even 40 companies before eventually getting a job.

    Getting turned down for a job can feel demoralizing. However, you should try to stay as positive as possible because every interview offers a learning experience.

    As Quora software engineer Udayan Banerji once shared in an article for Forbes, There is no shortage of amazing companies So dont lose hope. No matter who rejects you, walk in to the next one better prepared. If it takes 10, 20 or 40 rejections, so be it. Every interview you lose will teach you something. Take notes after each, improve on those. Rejections are not personal, not in the tech world anyway. And eventually when you get the job you want, these 12 years of rejections wont matter. You wont even remember it.

    Tip #: Dont Forget To Make Small Talk

    Yes, the focus of a coding interview is on a candidates programming savvy but the conversation will drive quite a bit of an interviewers impression.

    Interviewers are as human as the rest of us. They laugh, they share experiences, and they think highly of the people they like. When youre in the interview room, you should make an effort to push aside your nerves and make a connection with the person on the other side of the table.

    Chris Lee might have put the matter best in an article for Learn to Code With Me. An interview is not just about answering questions correctly, but also about a conversation. Ask good questions. Laugh and make jokes at appropriate junctures. At the end of the interview, even if you missed a few questions, the overall feeling the interviewer has about you should be positive. If you know that you are not a great conversationalist, make sure to focus on improving this.

    Interpersonal interaction matters so dont let small talk fall to the wayside!

    Coding Interview Tips:

    • Come up with a few good questions to ask your interviewer about their experience with the company.
    • Make a few jokes .
    • Make small talk.

    How Is This Repository Different

    Above all else, interviewers want to know that you have a solid grasp of the fundamentals, regardless of whether you acquired your knowledge through a degree program, a coding bootcamp, or some other way. Sure, its a nice bonus if an applicant can write in a flashy new language but generally, employers just want to know that the people they hire can problem-solve and write good code. Rather than trying to cram in a few impressive new skills on the day before your interview, set aside some time to brush up on your foundation and work through practice problems.
