How to Crack a Technical Interview?

Technical interviews are known for assessing the problem-solving skills, technical knowledge and core competencies of the candidate. Every software-based company is very particular while recruiting such candidates. These interviews are a mandatory part of the recruitment process of technical experts to check their ability. However, candidates often have a hard time cracking the technical interview owing to its level of difficulty. We have incorporated a list of best practices on how to crack a technical interview!

What is a Technical Interview?

Technical interviews are often conducted by employers who are looking to recruit candidates for engineering, computer and IT-based roles. Although not all technical interviews consist of technical problems, they are designed to understand the capabilities and technical abilities of the candidates. More often, employers assess your numerical and analytical reasoning abilities.

These interviews revolve around understanding your critical thinking skills, complex problem-solving skills and level of technical skill. You can expect an array of questions including brain teasers, numerical reasoning problems and technical assessment problems. Technical interviews can be conducted either by a telephonic interview, face-to-face video calls or in-person interview.

Format of a Technical Interview

Technical interviews generally consist of three major stages. However, depending on the company type, the size of the company, the job role and the experience of the candidate, these stages may vary. 

Phone Screen or Telephonic Interview

Post selection of your application, you may be asked to appear for a technical phone interview. This is your first opportunity to leave a good impression on your prospective employer. This part of the interview is usually taken by an HR member of the team. They may ask questions with regards to your professional background and resume highlights. At this stage, you won’t be expected to answer any technical questions, most of the questions are structured to assess your enthusiasm and interest in the company and the job role. You need to sharpen your soft skills while attending a telephonic interview. 

There are a few companies that often skip this stage of the telephonic interview and ask candidates to directly appear for the on-site or in-person interview. Professional and experienced candidates are often exempted from this stage of the interview.

At-home Assignment or Remote Coding Assignment 

Employers ask potential candidates to complete an at-home assignment or a remote coding assignment to evaluate their level of technical skills. This stage of the technical interview is very crucial as it is a great opportunity to secure an in-person interview. The type of challenge or task provided to the candidates may vary: 

  • Some companies will provide you with tools such as a CoderPad, Collabedit or even a Google doc along with a real-time monitored challenge to solve
  • Some companies may test your ability in programming languages and development of user interface which is also monitored in real-time
  • Certain start-up companies may simply give at-home assignments with a deadline of 24 or 48 hours 

Employers usually evaluate your coding skills and collaborative skills under this stage. Some small companies may choose to skip this stage of the technical interview and ask candidates to directly appear for the on-site interview. 

On-site or In-person Interview

Candidates who successfully clear the assignment or the coding challenge will qualify for the in-person interview. This is considered to be the most intimidating part of the entire technical interview process. The formality of the interview and questions may differ according to the size of the company. The major types of questions that candidates can expect are:

  • Behavioural questions
  • Situational questions
  • Technical questions
  • Educational background questions

Although not that common, certain companies include the whiteboard challenge as a part of the final stage of the technical interview. Here, you will be required to solve a complex programming problem or write a series of codes. Certain companies may even ask you to solve hypothetical UI/UX design problems. Employers often expect their prospective candidates to articulate and verbalise their thought-process and reasoning while attempting this challenge. The final round of the technical interview usually lasts for 30 minutes to 1 hour.

Tips and Tricks to Ace the Technical Interview

Now that we have gone through some of the best answers that you can pitch your interviewing committee, let’s check out how you can ace in the interview in an overall sense: 

Do a Thorough Background Research

It is vital that you do thorough background research of your prospective company. This will give you a fair idea of the potential questions that may be asked during your technical interview. Each company has their own personalised set of questions which are designed to test the suitability of the candidates for their organisation. The background check gives you valuable information on your prospective employer. It sheds light on the roles and responsibilities that you may encounter while applying for the job. 

Prepare an Elevator Pitch about Yourself

The basic question that is common to all technical interviews is “Tell me about yourself”. While this is the most predictable question that can be asked by any company, candidates often struggle to form a proper response and therefore fail to impress their prospective employers. Hence, you should prepare 30 seconds to a 1-minute elevator pitch that properly describes your academic background and achievements, past working experiences and career goals. This also gives a detailed glimpse to the employers regarding your communication and verbal skills. 

Consider the Tools and Skills Necessary for the Role

Before you proceed to your interview, keep in mind the basic requirement of the job role that you’ve applied for. You should review the job description in order to determine the concepts and fundamentals to ace the interview. A strong understanding of the technical tools and skills puts you in a better position to answer any question, no matter the difficulty. Therefore, prepare a basic outline of what you need to study or review before attending the interview. 

Regularly Practice Coding Challenges

As mentioned earlier, certain companies may expect their candidate to prove their abilities by completing coding challenges. Hence, begin your preparations in coding and programming languages from an early stage so that you are prepared to face any challenges that have been put forward by the employer. Go through past challenges and interviews of older employers to have an idea of the test. 

Have Confidence and the Right Attitude

During the process of the technical interview, employers do not merely look for the right answers. They also judge your ability to confidently answer the questions and the attitude and ease with which you handle the questions. Therefore, do not be eager to answer the questions immediately, think thoroughly before responding to the interviewer’s question. If you’re unable to answer a question, be frank and open with your employer, it portrays your honesty and confidence.

Be Verbal

Employers also assess candidates on the basis of their ability to properly articulate their thinking process while solving any challenges. This gives them a glimpse of the working process and manner of thinking of the candidate which allows them to evaluate whether they’re a good fit for their company. Do not hesitate to give your two cents while completing a project or challenge given by your prospective employer. Sometimes, employers enjoy valuable input from their potential candidates since it showcases their ability to reason and give constructive criticism. 

Ask Questions

There is a well known saying, “Curiosity killed the cat but satisfaction brought it back”. Most often, candidates are afraid to ask their potential employers questions or doubts while responding or solving assignments. This leads to more confusion and misunderstanding because of which they may fail to ace their technical interview. Therefore, you must write down questions or doubts that you wish to resolve during the interview. However, keep in mind that it is customary for candidates to hold their questions until the end of the interview. 

Manage your Time Efficiently

The more focused and prepared you’re for your technical interview, the more likely you are to pass it. Carefully calculate your answers and be precise while responding to any questions. Do not take a long time while solving any assignment or real-time challenges. As a matter of fact, while practising your mock coding or technical challenges, set a timer to ensure you complete your task within the stipulated time. The more time you waste while responding or solving a challenge, the less likely you are to be considered for the job position. 

Remain Calm and Do Not Be Afraid of Rejection

Rejection is a common fear among candidates and most often, candidates fail to appear for technical interviews due to their fear of being rejected by their prospective employers. However, it is important to know that you should not succumb to the fear of rejection and pressure that comes with every interview. Be confident in your own ability and skill set. Instead of seeing rejection as a mark of failure, see it as an opportunity to learn from your mistakes and improve your skills.
