Forging ahead, despite the pandemic
Uncertainty and ambiguity have been the central themes of the ongoing COVID-19 crisis. The macroeconomic aftereffects of the pandemic are likely to sustain for times to come. Diverse sectors of industries have been impacted by this unforeseen disruption, which has derailed their quotidian practices – the global markets are in a ‘wait-and-watch‘ mode. Social distancing and discretionary movement have taken precedence, bringing the hiring process to a virtual standstill. However, this has also allowed companies to revisit their recruitment strategies.
Amid the doom and gloom, various C-level executives in top tech companies are also hiring. They reckon software engineers to be the company’s real assets and maintaining business continuity hinges upon onboarding quality candidates. Therefore, they need fail-safe means to assess, interview and hire the most competent professionals without risking applicants’ safety.
It is well-accepted that HR professionals face constraints in hiring tech candidates as, often, hiring managers don’t understand what needs to be deduced in a technical interview. HRs are inclined toward traditional face-to-face interviews to assess technical candidates. There is nothing wrong in the process, but interviewers can only evaluate an individual’s characteristics, perception, opinion, and attitude, rather than hands-on coding skills. Add to that a long list of considerations, lengthy screening processes, wrong candidate filters or an outdated interview approach that impacts quality hiring.
Mathematical puzzles continue to form a part of the technical interview process.
These techniques may seem intriguing, but cannot circumvent a wholesome candidate selection that meets hiring goals. They do exhibit candidates’ intellect and craftiness or their levels of logical reasoning skills but don’t assess the real coding ability and knowledge needed for the job.
Hence, one of the ways that HRs can strengthen their recruitment process is by streamlining their technical interview process. They are closer to the goal to interview and hire the best by eliminating pre-interview inefficiencies and bringing clarity to the initial selection. The more refined your filter is, the more purposeful is your interview.
Here are the two prerequisites to conducting a successful tech interview:
An efficient interview process begins with choosing the right candidate for the interview via effective screening methods. Companies receive a vast number of resumes and often struggle to filter quality candidates. By using a combination of knowledge and application-based questions such as MCQs and coding simulators, hiring managers can gain a holistic, evidence-based overview of a programmer’s potential before advancing to the interview round. Here’s how:
Technical screening verifies more than merely the coders’ fundamental skills. It showcases their real-world coding ability, coding knowledge, language proficiency, usage of frameworks, etc. It ensures that employers don’t have to sit through time-consuming interviews with applicants who are neither qualified nor suited for a particular position. You’ll be amazed at the number of candidates technical screening weeds out. Also, valuable evidence-based analytics on candidate potential and performance deter hiring managers from biased shortlisting, leaving the company with the best for the interview.
The most common interview approach used by hiring managers to assess a coder’s capability is via Whiteboards. This interview approach traditionally involves using a whiteboard or paper to write an algorithm or an actual code instead of an IDE (Integrated Development Environment) or an editor. The coder is expected to use a specific programming language and solve a coding problem by penning down the process on the spot. Sometimes, whiteboard questions are simple wherein the candidates are asked to draw a circle or a grid using only an algorithm. They are also complicated, with more than one programming language to judge how coders handle complexities.
Such a traditional interview is conducted face-to-face with the candidates. The interviewers observe their approach to articulating a question, deciphering and solving it. They note every word and step taken by coders. They also acknowledge how often the candidates communicate and discuss their codes, uses and functionalities, which can take up to hours or even a day. Though a whiteboard coding interview is entirely unrelated to deciphering a coder’s on-the-job potential, recruiters have a soft spot for it.
There is now a growing consensus that this process is slow and unscalable. It is unable to simulate real-world problems, which negatively impacts the quality of hires. As technology becomes more affordable, and the demand for software engineers grows exponentially, writing code to test a candidate’s technical prowess on a whiteboard has become primitive.
How do hiring managers understand a candidate’s potential? How do they make technical interviews an experience and not a burden? Hiring managers need clarity when deciding what to judge in a technical interview.
Let’s elucidate what a hiring manager should assess in a technical candidate during a coding interview.
It includes, and is not restricted to:
In today’s competitive scenario, hiring managers must look beyond a candidate’s resume and redundant traditional interview approaches. They need to undertake an interview approach that provides a deeper understanding of a coder’s proficiency.
Time to embrace live coding interview as a game-changing interview approach
We understand the current scenario has disrupted the usual interview process. Hence, organizations must creatively assess candidates to improve the interviewing process for tech talent. Phenomenal tech advancements can enable companies to conduct their technical recruiting process virtually, without compromising their experience. Administering live coding interviews via online coding interview tools have lent incredible ease for the recruiters, regardless of the candidate numbers.
A live coding interview is a next-generation candidate interview process wherein the interviewer assesses a coder’s proficiency in real-time. A prerequisite to the interview is that candidates have to accept sharing their screen, video and audio. They are then asked to code in a programming language of their choice. Aside from the fact that the interview is being hosted remotely, it is as natural as a physical interview. It is also substantially more realistic than a traditional pen and paper, whiteboard coding interview approach. It offers the interviewer an accurate idea of how a candidate thinks and collaborates and utilizes various languages, frameworks, libraries or APIs.
In a live coding interview, the screen is split into three parts:
Live coding interviews often employ concepts such as pair programming interviews that mirror the coders’ real-life scenario, using the same resources people have on the job. Hence, it reduces the hiring time, without losing on quality candidates, also streamlining the process.
With a shared, live development environment enhanced by audio, video, and chat, hiring managers can undertake pair programming interviews to assess real-time skills and make quality decisions for tech candidates. This efficient interview approach in today’s remote hiring environment makes for an ideal online coding interview tool.
A pair programming interview is a modern game-changing interview approach. It is also famously used as an online coding interview tool that assesses a coder’s proficiency using embedded code simulators.
This agile and interactive practice consists of two people- the coder and the assessor. The coder writes the code, and the assessor (interviewer) guides them through the process to gauge their skills. Rather than making the candidate anxious, this concept boosts confidence by making the process quite conversational. During the interview, the interviewer and the coder can easily ask questions, voice opinions, and clear doubts about the next possible moves.
Pair programming also goes hand-in-hand with test-driven development (TDD). This means both parties get a real idea of the written code’s ability to function without errors.
Far more realistic than a whiteboard coding interview process, pair programming online gives the interviewer an accurate idea of how a candidate thinks, collaborates, and utilizes various languages, frameworks, libraries, or APIs. The pair programming interview is also possible remotely from start to finish.
When the interviewers are viewing the coders’ pair programming online, live, they are also listening to the coders explain the design decisions and the thought process behind it. Hence, the interviewers review the code’s performance and gain insight into the coders’ potential, focus and productivity, all in real-time.
Automated grading of online pair programming interviews replaces the static grading process, scaling an organization's interview capacity, which improves operations. Pair coding online eliminates the unnecessary back and forth while reducing human errors and inaccurately recorded information. This ensures a continual interview process, considerably shortening the decision-making and feedback process.
Pair programming interview enables evaluating the candidates thoroughly and objectively based on auto-graded simulators. Comprehensive reports elucidate the candidates' performance, offer a comprehensive summary of their attempt and enlists a detailed code journey. This thorough evaluation of a pair coding interview is free from hiring bias and ensures immediate results with optimum reliability and validity of a coder's potential.
Talented developers are in short supply, which requires being time-sensitive, or you risk losing out on top talent. Hence, the speed, efficiency, and convenience of online pair programming offer a hiring advantage. A custom environment can be set up seamlessly. One can create new and meaningful tests, quickly compiling any popular programming language with the pair coding interview. This saves time that can be utilized better in strategic tasks. Furthermore, a real-time review optimizes selection quality.
