How to Secure a Job Role as a Front-end Engineer
Not every applicant gets the job, and too often, candidates who do their due diligence are the ones who stand a chance. One would expect that having the skill is enough to get them on the job, and It’s not wrong to think that your qualification also plays a vital role in the HR decision-making process.
However, every organization has a unique taste in its choice of candidates. They all try to see who fits their goals and work ethic.
Certainly, you wouldn’t sabotage your organization's goal by playing the favoritism card. Perhaps you’d rather stick with a candidate who better fits your work culture and is fairly qualified over an arrogant candidate, which is the essence of interviews.
Interviews bring you closer to the candidate, beyond CVs and resumés. It helps those who see what’s behind that pretty face and appealing resume. And every interview question like the ones above is geared towards fishing out the ideal candidate amongst the herd of the applicant. How? Let’s find out!
HR expects some dynamics in your answer to interview questions. And as an applicant, you should provide these dynamics. Let’s explore how to provide dynamics and cut-fit answers to interview questions.
Know the Job
Landing a Front-end engineering job is challenging and seldom gets easier. But, for an applicant who already knows what it takes, securing the job becomes tard easier.
Organizations looking to fill a front-end engineering job role almost always publish a list of what they’d be looking for in a candidate. Your first job is digesting every bit of that job and paying attention to its details. When you see information like “we are looking for an applicant who can take the initiative and run with it, " it means they are looking for a candidate who is a team leader –a candidate that needs less monitoring to get things done.
When you answer questions or write a resume, it’s not enough to give a theoretical answer. You must show practicality. That’s all HR is asking for anyways! It’s a show, don’t tell ordeal. Anybody can quote or give non-practical answers to interview questions. But, if you are experienced enough to apply for the job, do more than give answers; take them on a journey of how you’ve implemented whatever you are saying and show the result you got.
One of the best ways to show experience is to make difficulty look easy. And there’s no better way to do it than provide concise or straightforward answers to front-end interview questions. Rambling has no use or positive advantage to it. Just say what needs to be said and leave out the excesses.
Take Your Time
One myth that surrounds interviews is the belief that “you’re expected to provide spontaneous answers.” Well, you’re not! What’s the rush anyways? Take calculated pauses to let your answers sink. It’s also a display of confidence, and you should learn to maximize the power that comes with momentary silence in interviews.
“Tell me about yourself.”
One of the most conflicting questions candidates might face in an interview is “tell me about yourself!” When asked, kindly note that HR is not interested in the fact that your mum gave birth to five kids or any answer that doesn’t concern how you can rightly fill the role.
Having airtight answers to possible interview questions gives you a headstart over another applicant. It might take a few practices in front of the mirror, but it’s the right way to stay prepared ahead of a job interview. Here are some of the possible questions you might want an answer
Q1. How do you practice front-end?
