A Guide to Ace a Technical Interview

Job interviews can be unnerving. A thousand thoughts are running through one’s head with preparations done days or weeks in advance. Imagine this, while you’re busy compiling all your necessary documents and memorising algorithm, chances are, there is a possibility that a dozen other candidates are doing just the same thing. Hence, how then can you stand out and put yourself at the forefront of the interviewer’s mind when it comes to picking the right person for the job?

In the tech industry here at home, there are a few types of technical interviews that are common practice.

1. Call Screener

A Call Screener is usually done when a candidate has been shortlisted for a position. It is generally treated as the first interview before he or she is called in for a face-to-face meeting. The interviewer might ask a few technical questions which should be simple enough to answer if your experience and background is well suited to the position.

2. On-the-spot Technical Interview

The candidate will be given a task to complete at the interview. An employer will likely opt for an on-the-spot technical interview as they would not only know how well-versed you are with the specialised subject at hand but also test your speed, critical and analytical thinking capabilities. So, remember that practice makes perfect. So be sure to brush up on any programming language that could be a little rusty. Being prepared would also help to calm fraying nerves during the interview.

3. Whiteboard

This type of test is an excellent opportunity to show off your technical skills. You will be tasked to solve a problem which requires knowledge in technical fundamentals. You will then be assessed by how well the problem is solved.

4. Spot the error

Usually used for more senior tech talents, the candidate will is given a code segment with mistakes. According to Dawe, this may mean locating syntax errors, logic problems, missed edge cases, or performance issues. An experienced candidate will likely be able to spot those errors and will be one step closer to landing the job.

Don’t Forget to be Human

No double your technical skills are of great importance but don’t forget beyond that; you will likely make the cut with the right attitude and mindset. Here are some vital interpersonal skills to nurture that would be a great accompaniment to your tech skills.

Communication Skills

We’re sure you’ve been told that this matters umpteen times, but it’s so important that we had to stress it again. Although your device will likely be closest to you at work, you will probably have team members, partners and potential clients. So, loosen up and look past that device from time-to-time, who knows what great friends you’d make out of your workmates.

Problem-solving Skills

Solving a problem brings all sorts of challenges, and when one gets frustrated, it can be easy to lose your cool— job interview or not. So while solving the task at hand can be stressful, do handle yourself well and keep calm. You’re likely to do better when you’re in the right state of mind too.

Critical Thinking

A well-rounded candidate needs to be able to see the bigger picture. Chris from LaunchSchool explains that “The goal is not to see if the candidate knows a specific piece of knowledge, but if they understand how systems interact and consequences of infrastructure decisions.”

Depending on the company, some may request additional interviews to meet with different levels of key personnel within the organisation. But, most importantly, like any other job interview, it would be wise to drop the interviewer a thank-you note via email. Hence all-in-all, be prepared, believe in your capabilities and give it your best!
