What To Expect in a Developer Interview


Interviews are the gateway to landing your dream job, but for most people interviews are a stressful and uncomfortable endeavour. You finally have your chance to impress a prospective employer and secure that golden opportunity, but unnerving thoughts and doubts begin to make you nervous. Nerves are to be expected, but if you let them overcome you, they could dampen your chances of securing the job that you may well have the skills and expertise for.

What is the best way to ease your apprehension? Being prepared.


Having an understanding of the overall interview process, the types of questions asked and what is expected of you will not only enable you to be more prepared, but it will serve to quieten some of them unsettling anxieties. So, what should you expect from a ‘typical’ developer interview? Every company has their own way of doing things and the procedure may differ slightly depending on the role that you are, but a lot of companies follow a similar process.


The interview process tends to comprise of one or two phone interviews, followed by up to four on-site face-to-face interviews. The initial phone interviews are used to simply screen candidates to assess whether they are worth meeting in person. The first of the two phone interviews (or first half of the interview, if there is only one) will ask primarily behavioural questions.


Behavioural questions are not designed to challenge you; they’re used to get you talking and to make you feel comfortable. Big open-ended questions are often asked such as “talk me through your CV” or “tell me about a challenging project you worked on”. The questions are designed to help HR professionals get a feel for you, the type of person you are and whether you’re a good fit with the company. Some light technical questions may also be posed asking you about your relevant coding knowledge, database expertise and so on.


Following the initial phone screenings, you may be invited in-house for a series of face-to-face interviews with the appropriate members of the team. Large companies such as Facebook, Microsoft and Google hold four face-to-face interviews lasting approximately forty-five minutes each. These interviews primarily focus on your technical abilities with only one focusing on your behavioural traits and/or culture fit with the respective company.


The technical interviews are a means of evaluating your problem-solving skills. The interviewer wants to see if you can translate your thought-process into reasonably correct, well-structured code. You will be asked a coding/algorithm question and be expected to write, test and optimize code often using a whiteboard, with some companies offering a laptop instead. Having a foundation in data structures and algorithms is really important. These are fundamental concepts, like binary search trees and breadth-first search. You will also be asked to develop an optimal algorithm for your code.


It’s important to note that your code and algorithm does not need to be flawless. It is your approach and methodology that is being evaluated. Once the technical side of the interviews are complete, you will be given time to ask questions that you may have regarding the role or company or whatever may be on your mind.


This is what a ‘typical’ developer interview process is like. However, every company is different.

Most in Demand Tech Jobs in 2019

Most in Demand Tech Jobs in 2019

Technology is moving at such a rapid pace that we are at a point where jobs that didn’t exist a few years ago such as data science are now some of the highest paid and most recruited for positions. Emerging technologies continue to be the catalyst for increasing demand as there are clear shortages of suitable talent for roles that simply didn’t exist before the technology emerged. Here are three of the most in demand tech roles across the EU for 2019. Cybersecurity Professionals European firms are poised to hire a large number of cyber-security professionals in the next 12 months to fight the increasing threat posed by hackers. A survey conducted by the International Information System Security Certification Consortium (ISC)² conveyed that up to 38% of European firms are set to increase their cyber-security teams by up to 15% in a bid to protect company information from potential cyber-attacks. The survey also relayed the massive talent shortage of cyber-security professionals within the EU that is projected to rise to 350,000 by 2022. This has led to a significant rise in salary and remuneration packages being offered to cyber-security professionals. Full Stack Developers We have seen a lot of companies seeking to remove the traditional departmental gap between backend and frontend developers by moving towards more agile and scrum methodologies. Full stack developers are able to seamlessly integrate the software layers and are aptly suited to work on cross-functional teams. Furthermore, start-ups actively seek out full stack developers due to their wide range of skills, they understand the full cycle of software development and can be a one man band in the early stages of a start-up. As a result, demand for full stack developers is increasing year on year with Indeed statistics portraying a 607% increase in the UK and a 207% increase in the US between 2015-2018. ​Data Scientists Data science is a vibrant field to be in at the moment. It carries a lot of dynamism in terms of the skillsets that candidates need to be successful, as well as the impacts that good data science can have on an organisation. In 2017, a report by the European Commission signified that the number of data professionals will increase year on year by approximately 14.1% by 2020. As data science is a relatively new field, there is a clear talent shortage with the European Commission estimating that 769,00 data science positions will go unfilled by 2020. Data science is a lucrative career being the highest paid profession on Glassdoor (in the US) for 4 years running with a median salary of $95,459. European counterparts such as the Netherlands and the UK offer a median salary of €69,000 and €65,000 respectively. Switzerland offers the highest salary in the EU with a median salary of €115,000. Machine learning and AI are two other areas within data science that are ones to watch. These innovative activities are very new but hold substantial future potential as they can be effectively implemented to improve business processes and products in a wide variety of industries. From predictive analytics to self-driving cars in the automation industry, this technology is going to influence the majority of industries in the future. Machine learning is one of the fastest growing jobs on LinkedIn with data showing that there are now 9.8 times more machine learning engineers than there was five years ago. The roles here presented are just a fraction of the growing roles within IT. Other prevalent jobs that are on the rise include; Web Application Developer Computer Systems Analyst Data Analyst & Data Administrator Mobile App Developer Market Research Analyst Blockchain Specialist UX & UI Developer


Automation - The Impact on Human Jobs

Automation - The Impact on Human Jobs

The robots are coming. Automation is a polarizing topic as despite the benefits and opportunities that new automation technologies offer, the impact on human jobs is a real concern. Regular reports warn that the automation apocalypse is coming within the next decade with studies from Oxford and McKinsey predicting that automation will eliminate 30 – 60% of all workplace tasks. These tasks which are carried out by human workers account for a significant portion of employment in some industries. Not all jobs are created equally, and some are more likely to be automated out of existence in the near future. To truly understand the reality of the threat that automation poses, we must examine examples of jobs that are at a high risk of automation. The long-standing staple of the taxi driver is likely to be a profession of the past. The taxi industry has already been turned on its head in a few short years with the introduction of apps such as Uber and Lyft. The human element of ordering a taxi has already been automated out of existence, is the driver next? Autonomous vehicles are no longer science fiction with major automotive brands heavily investing in autonomous technology. As the technology continues to advance and proliferate throughout society, it’s likely the lone taxi driver will simply be replaced by technology. The ‘Future of Employment’ have ranked taxi driver as one of the ‘least safe’ jobs with an 89% chance of being automated. On a similar note, truck/delivery drivers are likely to be a thing of the past alongside taxi drivers. We have already seen the first warning signs with Tesla’s fully electric autonomous semi-truck entering the market. Imagine; you order an item through a well-known online retailers’ website. All payment is made securely through the website, you provide your delivery address while ordering, but instead of your order being collected from a warehouse by an outsourced delivery partner, which is often the case at the moment, a dedicated robot tracks the order from the warehouse/ It is then loaded into a self-driving vehicle/drone and delivered safely to you, with no human interaction whatsoever. Amazon have already trialled this new tech using drones to offer same-day delivery on small Amazon purchases. US Netflix series Black Mirror provides many insights into the future of our society and how technology influences it. Take episode three of season four, Crocodile. In this episode, an autonomous pizza truck delivers a pizza while cooking it in-transit. It sounds like science fiction yet in Silicon Valley, a company called Zume is pioneering the concept of a ‘robot pizza truck’. An order is placed through the Zume app, the self-driving truck begins its journey to the destination address, and by the time it has arrived at the delivery address, the robot chef will have a freshly baked pizza ready for delivery. Household brand PizzaHut came out in 2018 saying it was teaming up with Toyota to bring the robot pizza truck concept to life. The ‘Future of Employment’ has ranked fast food cook at an 81% risk of being automated. The pizza truck will automate both fast food cook and delivery driver out of existence. As well as the food, e-commerce and driving industries, another area which faces potential extinction in the coming years is that of customer service. Customer service spans across a range of roles, yet a significant portion of these roles are on the way out. UI chatbots continue to proliferate throughout many large organisations removing the need for customer support agents. As this technology continues to improve and become a more cost and time efficient method of customer support, why would companies choose humans? Evidently, automation poses a higher risk to some industries more than others. Jobs that are highly routine with a high proportion of repetitive tasks are most at risk of being automated in the near future. However, this does not mean the job in its entirety will disappear, automation will change how we work. The reinvention and re-engineering of jobs is the key story, not job losses. For example, automating the last kilometre of truck deliveries is an inconceivable task at the movement, the journey still requires a qualified human driver. Customer service agents can upskill and work in other areas of the business such as sales or account management. Technology and automation have always changed how we work throughout history without causing an unemployment apocalypse. Automation will no doubt change how we work but the threat it poses can be mitigated by continuous upskilling and reskilling. Jobs will change, it important that we change as well.

What to Wear to a Tech Interview

What to Wear to a Tech Interview

As the old saying goes, first impressions count and that is never truer than when it comes to an interview. How you present yourself paints a picture in the prospective employer’s mind of your interest and dedication to landing the position. But does this apply to whne interviewing with a tech company? ‘Silicon Valley’ culture has strongly influenced the IT industry uplifting many long-standing traditions in the world of business. The stereotypical ‘IT guy’ is depicted as a laid-back person wearing jeans and a hoody at best, but is this appropriate when interviewing for a full time position? There are a number of things that must be taken into consideration when gauging what to wear to a interview. First and foremost, it is important to note that tech positions are open in a wide array of industries ranging from a small tech start-up to a global bank. The culture and industry in which the company operates in will dictate what you should wear to the interview. For example, in a bank, formal business attire is expected and worn by nearly all employees. If the employees are wearing suits, you should suit up for your interview. If a suit just isn’t for you, dress smart. A co-ordinated, well fitted smart outfit with dress shoes will suffice. A bank is a very black and white example. The tech scene is a different story, where the lines can oftem become blurred. Most of the top tech firms dress more on the business casual side, making it hard to gauge what is deemed office appropriate. Smaller tech firms can dress very casually, with a suit not being expected or even appropriate. A good trick is to research the company’s culture through a simple Google search, Glassdoor and LinkedIn or even try speak to an employee of the company to get an idea of what is expected. Interviewees are always susceptible to underdressing to match the company culture. It is recommended to always dress professionally, no matter what type of company you are interviewing with. Your appearance signals who you are, your professionalism and your commitment to landing the job. Men should consider wearing trousers or khaki pants with a long sleeve shirt and dress shoes. No jeans or trainers, its simply too casual for the occasion. Women should consider wearing a pencil skirt or trousers with a collared shirt. A work dress is also suitable. Wear whatever you are most comfortable in but err on the side of overdressing. Whatever you decide to wear, ensure the clothes are clean, crease free and the shoes are polished. Good personal hygiene and care is a must. For men, make sure you’re clean shaven or your beard is very neatly trimmed. If you use hair product, go easy with it. For women, keep the make-up light and professional. If you have a lot of jewellery and/or piercings, best to take a minimal approach to both. Make sure your nails are neat and if you are wearing nail polish, make sure it’s not chipped. Last but not least, try not to use overpowering perfume or aftershave - a subtle scent is best. During an interview, there are a lot of variables outside of your control, so why not make the most of the variables you do control. Research has shown that the first few seconds of meeting someone is the most crucial, with the visual impact you make being the most important factor.
