Cracking the Technical Interview

Covering a wide range of topics will help you answer and solve a lot more questions than an average candidate.

Youâll also be asked questions about the languages you are proficient in.

In addition, be prepared to answer any questions pertaining to the technical projects youâve mentioned in your CV or portfolio of work. Some of the interview questions could be around the tech stacks used and the reasons behind using them, challenges faced during the projects, and how you tackled them.

After The Technical Interview

When the technical interview is over, take a breath: you made it through! There are a few things you can do to follow up, but for the most part, its just a waiting game now.

Tips for after the tech interview

  • Keep some emotional distance from the process. Expect to get rejected a lot, and its important to not view it as personal judgement, advises Chris.
  • Even if you dont get the job, have the perspective that the interview was great practice for the future. If it was your first one, now you know what to expect from a technical interview! Glean insights from the experience and use them to propel yourself forward.

How to be a memorable candidate

Send a short and sweet thank you email to the recruiter/hiring manager within 24 hours of the technical interview.

Make a note of everyone you speak to during the interview and reach out to them with a quick note of thanks as well. You can send emails to them individually if you made more of a connection, or send a group email with a general note of thanks to everyone. It will definitely help the team remember you!

If you havent heard back after a week, send a brief follow-up email to the tech recruiter or your possible future manager, reiterating your interest in the role and asking about potential next steps.

Dont Get Demotivated If You Fail To Answer Some Questions

Often for the interviewers is not that important if you answer right away to all of their questions. They also look closely who you approach their question. Keep your cool, do not answer right away even if you heard the question before, breathe and take your time. And if you havent come with the solution after 3-5 minutes you can just tell straight away that you cant solve it so he/her can proceed with the next one.

You should always try as hard as you can to answer the questions. But if you donât know the answer to a question or cannot find the solution to a problem, say so. Perhaps, the interviewers may ask you to explain to them where youâre stuck and nudge you toward the right answer/solution. Pretending to know an answer is not a good idea â your pretense will show.

Meaningful Questions To Ask The Interviewer

Interviews are a two-way street. You should be learning about them just as much as theyre learning about you!

Asking thoughtful questions is also a good way to stand out in the interview. The age-old adage people dont remember what you say, but they remember how you made them feel is so true when it comes to interviews, says Refael . When a candidate keeps the flow going in a friendly conversation, instead of making me feel like I am conducting an interrogation, I will remember our brief time together fondly.

Of course, you should tailor your questions to the specific situation, but here are a few meaningful questions you can ask:

  • What do you like most about working here?
  • What frameworks, tools, tech stack, etc. does your company use?
  • Can you describe the development process here?
  • How do you test your code?
  • Does the company offer opportunities for professional development, training for engineers, etc.?
  • Whats the most challenging project youve worked on here?

The other upside: while youre listening to their answer, you get a little break from talking!

Tip : Dress For Success

No matter what the position is that you are applying for or what the company culture is, dressing professionally is necessary. Other than the unlikelihood that the employer specifies otherwise, a business professional outfit is appropriate in almost every situation. Be aware of strong cologne, perfumes, hair spray, and other smells. Any such product should be used sparingly as to not distract the interviewer. Details are important so make sure your shoes are dirt-free and shiny and your clothes are ironed and laundered. Makeup and jewelry should be kept to a minimum.

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, lets 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.

Onsite Interview And Whiteboard Challenge

Now weve arrived at the most intimidating part of the entire tech interview process. At tiny startups, onsite technical interviews might be a lot less formal than at bigger companies. Heck, there may not even be a whiteboard to do a coding exercise on! Still, whatever the company size, it never hurts to do coding interview preparation so youre ready for any situation that may arise.

What to do during the onsite technical interview + whiteboard challenge

1. Ask clarifying questions before you even start writing code.

I appreciate it when someone takes the time to evaluate the question he faces in the interview, says Refael . It shows me that this person is calculated and rather than just writing code, he sees the whole picture.

Ask questions around assumptions of the question, and try to reason about the question from a bottom-up perspective, adds Chris.

2. Talk through your code to give the interviewer a window into your thoughts.

What happens in a technical interview is as much about the journey as the destination. Its designed to test a candidates communication and problem-solving skills, says Refael. More important than the solution is how they work at getting the solution. Can they articulate their thoughts while writing out the code on the whiteboard? Are they putting together a clear response to the question?

3. Speak clearly and precisely.

Things To Keep In Mind While Preparing:

  • Well, the first thing is to stay focused. Come what may, don’t let your dedication and enthusiasm die in any way. As they say, ‘diligence is the key‘.
  • Having a knack of solving every problem at hand without giving up, is a skill that should be acquired, if not present naturally.
  • Knowledge of basic data structures and algorithms is always useful, whatever the profile you’re applying for may be. Lists, graphs, trees and sorting are some fundamental concepts that one should have a grasp on.
  • It should also be noted that most of the tech companies use Whiteboard Coding and do not provide laptops to code. The prime purpose of whiteboard coding is to allow you to speak more about your thought process. So there may be times when you cannot come to the exact solution, but do make sure that you speak your mind out in front of the interviewer. Though many may think that it becomes very difficult to code on a whiteboard since we are always coding on computers, the interviewer does not expect you to write a perfect code as there can always be syntactical errors. Another advantage of whiteboard coding is that you do not need to write the complete class definition and boilerplate code. But do keep in mind that you should not write pseudo-code.
