How to crack a coding interview

If approached correctly, it does not matter if it is a coding interview or any kind of job possible. The interview can be one of the easiest aspects of a company’s recruitment process; otherwise, it can be one of the most difficult obstacles to overcome. I’ve watched people struggle for a long time in coding interviews, and just a few of them have been chosen in the end. That is why the purpose of this article is to assist you in understanding what a company looks for in an interview and how you can prepare for it.

We are going to separate or article on three little interviews that will get you the job you always wanted. Follow this article step by step, and you will be unstoppable. 

The recruiter interview

How to crack a coding interview

A recruiter is a person who has a one-on-one chat with an employee, but he is not a management or appointing authority. The recruiter delivers your resume to employers who require the abilities you possess; he should be aware of the job’s requirements and then select employees based on the employers’ desires.

He assists the employee or applicant in practicing for the real interview and building confidence. This recruiter interview is an initial interview, so be on your best behavior and dress appropriately for the job.

If you are wondering how you can make a perfect first impression here are some advice:

Demonstrate the fundamental abilities that qualify you for the position:

HR personnel or recruiters will often not look at your educational qualifications or other important aspects such as technical skills; instead, they will look at whether you are qualified for the position and meet the minimum standards.

They will send potential applicants to company authorities and hiring managers after the basic interview; the recruiters will merely examine the baseline requirements.

Recruiters will always encourage you to conduct thorough research of the job description and list of required abilities. Always remember to emphasize your experience and accomplishments, and if you are employed as an interrogator, attempt to be on time.

Demonstrate your excitement for the job by:

Recruiters always favor candidates that are enthusiastic about the job and also possess the necessary skills. If you only have the qualifications but show no interest in the job, the recruiter will assume you are not interested; thus, demonstrate your willingness to the recruiter.

This produces a favorable impression on the recruiter, who will recommend you to the company’s recruiting managers if he believes you will be a good worker and perform well in the position.

Show that you fit in their team environment

The last condition is important since the worker must stay in the workplace for at least a few hours each day, and if he is not comfortable, it will impact his working capacity and performance.

So, first, try to learn the workplace culture and requirements by speaking with the employees, and then do your best to blend in. Follow the firm on social networking sites like Facebook and Twitter to learn more about the work environment and culture; do an online search on the company to learn more about its requirements and employees.

These were just some basic points to complete the first interview on the right foot. 

The technical interview

The interviewers need to understand more about your technical skills after you amazed the recruiter. An online technical coding test will be issued to you to evaluate your programming, development, and technical skills. This is your chance to show your abilities.

Do background search:

So for the first step, I chose one of the most important ones, which is the background search about the company you want to be part of. Before sitting in the interview you should know some things about them, like whos the most used programing language etc. Knowing all this you can study and refresh your knowledge some days before the interview happens. Also, you will be able to ask the right question about the job.

Utilize your time:

Usually, there is quite some time that separates the initial interview from the real technical one. You better use this time and practice some of the most common questions that might happen in a technical interview. The interviewer might ask some questions on topics that you feel rusty about and forgot about the answer to. 

Don’t get demotivated if you fail to answer some questions?

Often for the interviewers is not that important if you answer right away to all of their questions. They also look closely who you approach their question. Keep your cool, do not answer right away even if you heard the question before, breathe and take your time. And if you haven’t come with the solution after 3-5 minutes you can just tell straight away that you can’t solve it so he/her can proceed with the next one.

Use logical algorithm:

If you can’t code the whole solution because of many factors you can always ask the interviewer if you can proceed with the solution with a logical algorithm. This solution can be way better than no solution at all. 

Stay cool:

The trinity for the interview to go well is: being confident, smile and maintain eye contact. If you keep your cool, you will be able to think clearly, take your time and you can show them exactly what you can do. 

The final interview

The final interview is focused more on your soft skills. For a company is not important only if someone can do his job good in his little corner but also if he/she can work and cooperate on a team project. Most of the questions at this stage will be about your creativity, communication, teamwork, problem-solving, etc. Try and show your interviewers that you are a team player and everyone can rely on you how you would on them.
