How to Master the Technical Interview (Part 1 in our 2-part series)

In what may be one of the most stressful technical interviews on record, Lee Ballentine was interviewing for an applications engineer manager position with the CEO of a Silicon Valley company in the mid-1980’s when the room began to shake. As the shaking intensified and books started falling off the shelves, Lee watched people running by the room he was in towards the building exit. Seemingly content to ride out the earthquake, however, the CEO did not flinch and kept asking questions. Lee figured that if the CEO could handle the stress, so could he, and so the two kept right on talking until they were the only two left in the building. This unusual interview eventually concluded around the time everyone had calmed down and returned to work, and a few days later, Lee was offered the job.

While a technical interview can certainly be a very stressful experience, the good news is that it most likely won’t involve an earthquake. In addition, there are a number of things you can do to prepare that will reduce your stress levels, increase your chances of success, and hopefully land you that coveted position.

About the Technical Interview

Technical interviews are common amongst companies recruiting for IT, engineering or scientific positions. For many companies, technical Interviews are used only for the top candidates at the end of the process. Essentially, this type of interview is designed to determine your level of technical knowledge in an area that is specific to the position for which you are interviewing. You may be asked to give a presentation on previous work, projects, or success stories. Other times, you may be given a problem to solve in real time, requiring you to walk through the solution on-the-spot. If you are interviewing for a position requiring a scientific or engineering degree, you may be asked to work out a solution to a problem on a whiteboard in front of the interview team. Although assessing technical knowledge is obviously important for a technical position, the interviewer will also want to know how you think, problem-solve, communicate and interact with people.

In a technical interview, candidates may be asked questions that:

Whether you are presenting your project history or working through difficult questions one-on-one,  the interviewing team is not so much looking for the “right” answers as they are trying to gain insight into how you think and problem-solve, and how you communicate your thinking.

Though facing a technical interview may at first appear daunting, there are ways to prepare. Preparation is, in fact, essential to mastering technical interviews – this is not the place to just wing it.

Preparing for the Big Day

Interview preparation allows you to go into an interview empowered to engage your interviewer(s) with questions and comments, as opposed to just passively submitting to an evaluation of your skills and knowledge. As early as possible before your interview, you should start preparing in a number of ways:

During the Technical Interview

Doing the homework described above can go a long way towards setting your mind at ease before a technical interview. Armed with the knowledge from your preparation, it may be helpful to think of the interview more as an opportunity to meet and interact with company employees in order to determine if this is the right fit for both you and the company. The experience is really what you make of it. Why not take advantage of this chance to meet with others knowledgeable in your field in order to learn something new, for example?

Here are some things to keep in mind in order to make your technical interview a success:

Someone who goes to an interview just to get the job and get out, will likely turn into a bored employee who just punches the clock and collects his or her paycheck. At an ideal job, you’re growing, communicating, learning and contributing every day. The above suggestions allow you to begin creating an ideal job for yourself by demonstrating the qualities during an interview that employers are looking for.

At the End of the Interview

You know an interview is coming to a close when your interviewer asks you, “Do you have any questions for me?” Never say “no” to this question, as it communicates that you are not interested or prepared. Instead, ask the questions that came up for you while you were researching the company and the job. Ask about the team you will be working with and the biggest challenge they face at this time, for example. Avoid questions about vacation time, salary, benefits, and other what’s-in-it-for-me questions  at this time – these questions are more appropriate for a human resources rep after you’ve been offered the position.

Finally, after you walk out of that room, don’t stop interviewing for the job. Send a short thank-you note or email as soon as possible that addresses specific and relevant issues you discussed during the interview.

In Closing

There are a number of different formats for technical interviewing. Not all technical interviews will be conducted face-to-face some might be telephone interviews, while others might be conducted over Skype or Google Hangouts. You may encounter one, some, or all of these formats during your interviewing journey. We’ll explore the nuances involved in the next piece, “How to Master the Technical Interview – Part II”.
