What Does Cors Mean And How Does It Work
From Mozilla:
Cross-Origin Resource Sharing is an HTTP-header based mechanism that allows a server to indicate any origins other than its own from which a browser should permit loading of resources. CORS also relies on a mechanism by which browsers make a preflight request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request.
Make Sure You Understand The Question
Before you start writing code, take some time to think about the challenge. If you need any clarifications, ask the interviewer to repeat the question or clarify something.
It may sound like you are doing the right thing by getting to work immediately. But your brain needs time to think about the problem before you can get started. If you ask questions, you can make sure you know exactly what they expect of you, and you can show the interviewer that you value clarity.
Research Standard Technical Questions You Might Expect For Your Job Role
Every job has different technical questions pertaining to specific responsibilities and situations. Because of this, review online resources that provide sample technical questions for your job or industry. This can help you get a better idea of potential questions to expect at your technical interview.

How To Pass A Technical Interview
After taking all the steps to ensure that you’re ready to put your best foot forward, it’s time to take your technical interview. Technical interviews can occur both in-person or remotely. If it’s in-person, you may be asked to write your code on a whiteboard. If it’s remote, you might use a code editor.
Regardless of where it’s held, there are several steps you can take to make sure your technical interview is a success.
Technical Testing Aka Whiteboard Tests Aka Code Tests
Up until this point, weve been talking about interview questions the standard back and forth you can expect in job interviews across many different fields.
And just like how another job might require you to prove your skill set in some way, many technical jobs require you to show your design or development work. These are known as technical tests, whiteboard tests, or code tests.
Code tests are often the most dreaded portion of the technical interview, especially for beginners in the field. But just like the rest of the technical interview, there is plenty you can do to prepare, and youre not expected to execute flawless code live in an interview. Its all about how you work through it.
Technical interviewers might ask you to do one of these types of tests to show them how well you know your stuff: project-based tests, logic tests, or live problem-solving tests.
Lately, project-based tests are more common than live tests, likely due to the pandemic and the turn to remote work.
In a Dice article in 2020, Nick Kolakowski found that with COVID, project-based assignments were replacing live problem-solving tests because interviews as a whole were being conducted virtually.
While its possible to code live on a Zoom call, it might not be ideal, and some companies may throw out that portion of the interview altogether if the interview is remote.

Stages Of The Technical Interview
In general, the technical interview consists of 3 stages:
Stage 1: Phone screening The candidates resume has been selected, and the company wants to know more about the candidate. Basically, in this stage, the company contacts the candidate to inform them about the section of their resume and see whether they are enthusiastic and eager to proceed to the interview rounds.
Stage 2: Assignment/ remote coding assignment Employers should then test the candidates skills before proceeding with the personal interview. In this preliminary test, the company will provide the candidate with an assignment or an examination relevant to test their business. The candidate would be required to solve the task simultaneously and submit it to the company. Employers could use specific online or in house tools for candidates to give the test.
Stage 3: Whiteboarding challenge/onsite interview Employers call the 3rd stage the real technical interview round. In this stage, the employer calls the candidate for a personal interview and gives them a coding challenge to solve under the whiteboard interviewers supervision.
Most Common Technical Interview Questions
Are you interviewing for an IT job? If so, you should prepare to answer technical interview questions designed to determine whether you possess the hard skills required to do the job well.
During the job interview, you will need to share examples of your skills as they apply to the job for which you’re interviewing. Taking the time to match your qualifications to the job description will make it easier to respond.
Review this list of the top technical interview questions that are most often asked by tech employers and recruiters. Depending on the job you’re interviewing for, you will be asked about the skills, experience, certifications, competencies, language, processes, systems, and tools you have that are a match for the job requirements.
As you structure answers to the most commonly asked questions, jot down anecdotes and specific examples from your previous work experiences so that you have plenty to elaborate upon.
In addition to practicing your responses to these questions, you should also be ready to take advanced skills tests to prove your level of aptitude in software programs, coding / programming, and / or web development .

What Is A Non
When youre interviewing for technical jobs, youre going to have to ask technical questions.
However, to get to know your candidate and his suitability for the job hes applying for, you must ask some non-technical questions too.
A non-technical job interview is a job interview that does not focus on technical knowledge.
In this article, well show you the most common types of non-technical questions, some uncommon ones, the different types of non-technical questions you can ask, and a few other things too.
Live Problem Solving Aka Whiteboard Testing
One last potential test type is live problem solving. As its name implies, for this test, youll be asked to solve a problem during the interview itself, often in the form of a whiteboard test. Many new developers are the most nervous about this kind of test, and thats understandable.
If youre new to a field, it makes sense that having to prove your readiness could be scary. Just like other technical tests, live problem-solving tests arent about getting it right so much as showing your work and how you approach problem solving.
While the logic based test is more often a test of your theoretical reasoning skills, the whiteboard test tackles your practical coding skills and knowledge base. It asks you to solve a problem based on what you know about the theory and practice behind programming.
One example of a problem solving test is to return the indices of two numbers given an array of integers so that they add up to a specific target with the assumption that each input would have exactly one solution and the same element cannot be used twice.
Another real world example is the palindrome challenge. A palindrome is a word or phrase that reads the same backward as forward, like Hannah or taco cat. The problem youre given can be to return true if a given string is a palindrome and return false if its not.
Conversely, if the reversed string isnt the same as the original input string, the latter is not a palindrome and your function is expected to return false.

Technical Interviews Are Conducted Using Purpose
Software engineers have been loath to recall requests to write code in a shared document, like Google Docs, when a proper integrated development environment isnt available.
An IDE allows interviewers to see how candidates normally develop or debug code, verify its functionality, and develop their write-ups based on a relevant interview rubric. These features dramatically improve fairness to candidates, ease, and accuracy for interviewers, and improve the effectiveness of the hiring process.
Proper technology for conducting a technical interview:
- Allows candidates to run their code in an IDE
- Includes video chat between the interviewer and candidate
- Supports the interviewer with a pre-approved interview question and format that will ensure interview consistency
- Removes opinion-based recommendations by allowing an interviewer to enter a rubric-based structured write-up that drives the recommendation
Inside The Technical Interview Project
Clement created a sample project to demonstrate how we use GitLab to power our technical interviews.
In the gl-commit-example group, there is a subgroup with all the interview projects we are seeding to the imaginary candidates, a template, and a project seeder.
The interview project’s subgroup, template, and project seeder application lives inside the sample project for the technical interview.
Inside the template, there are GitLab pages and the interview test merge request.
The assignment here is pretty simple. The candidate needs to update the website to say “Hello GitLab Commit SF,” but in order to accomplish this, the candidate will need to fix the failing pipeline.

What Coding Language Are You Most Comfortable With
The interviewer will probably ask you a question about the coding languages you know to determine whether you have a comprehensive understanding of how to use the language they expect you to use and whether you are comfortable using more than one language. When answering this question, it is important to mention the specific coding languages you have worked with and are comfortable with. Then, choose one specific coding language you are most comfortable with and explain why.
Example:”While I am comfortable with several types of coding languages, including SQL, Python, C++ and Visual Basic, the coding language I have the most hands-on experience working with is JavaScript. Because JavaScript was the first coding language I learned and I have used it on several projects over the past 10 years, this is the language I am most comfortable with.”
Tips For A Positive Interview
