Crack Interview

Guide to crack the coding interview in any top software development /IT company

Updated on


If you’re looking for a job in software development or IT, you’ll have to interview at some point. The good news is that interviews are designed to be challenging. The bad news is they’re also designed to make candidates fail!

The interview process typically involves a series of coding challenges and problems, with some companies also including behavioral and soft-skills interviews. Common interview questions can range from simple coding problems to complex algorithmic questions. That’s why it’s important to know what to expect and prepare accordingly. But don’t worry, with the right preparation, you can ace the coding interview and land your dream job. Let’s dive in and explore the key areas you need to focus on to impress the hiring managers.

Follow our tips, and you’ll be sure to come out on top!

Resume Preparation

A resume is the first impression of a candidate. The resume should include personal details, contact details, educational details, coding skills, and other relevant information that can help you to prepare a good resume.

In today’s digital world, there are many online tools available to build your resume in few seconds just by filling up some fields including education qualification, job experience, coding skills and so on. Most of these tools will also suggest relevant keywords based on your profile which helps recruiters to find you easily when they search for specific profiles from their database or from outside sources like LinkedIn or Facebook etc. There are many paid as well as free options available in the market so choose any one according to your needs & budget constraints and start building!

Practice projects using the technologies you’re applying the job for.

You should create practice projects to build your portfolio and show off your coding skills for coding interviews. These projects can be done in a team or individually, but you need to make sure that they are relevant, realistic and use the technologies you’re applying for. I would recommend that you host these projects online using free tools like Netlify, Github, etc.

Prepare for common interview questions, body language & etiquette

The interview is the most important part of your job search, as it’s a chance for you to show off how well you can do the job. The first step in preparing for a coding interview is to know what common questions employers ask and how to answer them. Questions like ‘Tell me about yourself,‘ or ‘What are your strengths and weaknesses?‘ are very common, so be prepared with a short elevator pitch (1-2 sentences) that shows off your personality.

Additionally, try coming up with a list of 30-60 minutes worth of questions (with answers) that could be asked during an interview process if you’re lucky enough to go through multiple rounds. You might be surprised by how challenging this can actually be

Also, remember that body language speaks volumes during an interview—so make sure yours says “I’m confident” rather than “I’m nervous.” This may seem obvious but remember: even though they will most likely not ask anyone else what they think about their interviewing skills before choosing who gets hired, they’ll certainly notice when someone lacks confidence during interviews; it’s something we humans tend to pick up on quickly!

If possible practice answering questions aloud in front of friends before going into the actual room because this has helped me tremendously with realizing where my voice tends toward being too quiet or too loud while speaking out loud at work–it helps identify these issues early on so we can fix them later!

The interview process for software/IT development roles

The interview process for a software/IT development role is different for every company, and a general set of guidelines won’t help you much. However, below are some tips to help you understand what to expect in an interview process:

  • The first step of the interview process is usually a phone screening with HR or someone similar. They will ask you about your resume and experience, why you want this job, how long you have been coding and more. It may also include some pre-scripted technical questions like “How would you solve a problem using Java?” or “What are some programming languages that allow developers to write code faster?
  • The second step is usually an initial technical interview where they will ask more complex questions about algorithms or data structures (e.g., binary search tree). They may also give you example problems related to their business domain such as building filters based on keywords in emails from customers. You should try solving these problems on paper rather than typing up answers because it shows better communication skills! It does not matter if your solutions are perfect – just make sure that they can understand what went through your head when coming up with them!
  • Once both steps above have been completed successfully by candidates standing out during the process so far (i.e., those who had impressed us), our next step after contacting HR would be scheduling interviews with managers who make final hiring decisions within their respective departments here at Company Name.

How to prepare for programming questions?

It’s important to know the technology you’re applying for. After all, it’ll help you get a job in the first place!

Here are some tips on how to prepare for programming questions:

  • Prepare for Programming Questions—Practice with Mock Interview Questions & Answers

Get your hands dirty by practicing with mock interview questions and answers. You can find many good sources of coding quizzes online such as Leetcode or Hackerrank, which offer paid services or free access depending on your needs.

Prepare for the online coding tests

It’s common for software development/IT companies to have their own proprietary coding tests, in addition to the ones you might have prepared for in advance. The good news is that you can find plenty of resources online to get a head start on these tests before you even start applying.

Some employers will give you advanced notice about an upcoming coding test so as not to make it too difficult for applicants, but others will just throw one at you right when they are scheduling interviews with other candidates. If this happens, don’t panic—just treat it like any other interview prep session and try your best!

If they do give enough notice, take some time over the next week or two before your interview date to practice online coding tests (assuming they tell you what language they’re written in). You’ll want a few hours where no distractions are possible—it’s better than cramming since it allows ample time for planning out solutions and debugging mistakes after each submission!

Practice with mock interview questions & answers

The best way to practice for your interview is to do mock interviews.

Practicing with a friend, family member or partner, who can act as the interviewer and ask you questions. It’s like a role play but you actually get feedback on what went wrong and what could have been done better in each scenario. You should also try practicing in front of the mirror so that you know how your body language looks like when answering the question(s).

Try getting some professional help from a career coach or an experienced recruiter who will be able to spot weaknesses in your CV/resume/personality and give tips on how to improve them before going for an actual interview at any top software development company

What if you don’t know the answer?

When the interviewer asks you a question, the worst thing you can do is try to answer without fully understanding it. When this happens, your mind will be racing and you’ll end up looking like a bumbling idiot. If you don’t know the answer, be honest and say so (but in a confident way). You might be able to get more information on the question or time to think about it before providing an answer.

You might have questions of your own: “Could I see that again?” or “Could we discuss this in another meeting?” or even “Wouldn’t it make sense to research this question first?” These are all valid requests from candidates in interviews; there’s no reason why any candidate should feel embarrassed by asking for more information or clarification when something doesn’t seem right.

Ask relevant questions to interviewers

  • Ask questions to understand the role better:

To evaluate the role better, you need to ask questions regarding the scope of your responsibilities and how it will be assessed.

  • Ask questions to understand the company better:

You can also try asking about their product development process, technology stack or any other areas where you think your expertise can help them improve their work flow or increase efficiency.

Common mistakes in the interview that most candidates make

As an interviewer, I have to say that it’s not uncommon for me to be impressed by the candidate’s skills in their CV and on their Linkedin profile. But when they come into the interview room, they can suddenly become a different person: sometimes too nervous or shy; other times arrogant and rude. As a result, they end up making mistakes that are so common that I’d like to share them with you here.

  • Being late for your interview (or worse, being late without informing us)
  • Being rude to the receptionist or other members of staff at your company
  • Not doing any research about our company (and maybe even worse – lying about your knowledge of us)

Don’t lose hope, get help from others, seek feedback and keep trying

If you are one of those people who got stuck at a particular interview question, don’t lose hope. Most of the time, it’s not due to your own lack of knowledge or skill, but because there was something that was not mentioned in the question description. For example, an interviewer may ask you to write a program that reads and processes user input, but is actually looking for how well you can write code while handling user input and errors gracefully. In situations like these, it’s important to ask questions such as “What exactly do you mean by…” or “Are there any special requirements associated with this task?”

If your interviewer doesn’t clearly provide clarification then seek feedback from others (preferably seniors). This will help both you and them because they can better understand what kind of questions they need to ask and how they should describe them on their list while also helping you learn new things along the way!


You have made it to the final step in your job search.

This is where you will meet your future boss and get hired as an entry-level employee.

How do I prepare for an interview with a top IT firm?

Step 1: Learn about the company you are applying for and prepare accordingly

Step 2: Find out what they do, why they do it that way, what their values are & how they treat their customers (if any)

Step 3: Figure out which team or department would suit you best, depending on your skillset or interests.

Also, think about if there is any role playing be done during this meeting such as coding on whiteboards etc (not always necessary but might help if you’re nervous). Take note of any possible questions that could come up during this interview & prepare a few responses for each one based on how well-suited would these positions be to you personally.

Remember, cracking an IT interview requires a lot of preparation and hard work. However, it’s not the end of the world if you don’t make it through. Take it as a learning experience and move forward. Keep working on your technical and soft skills. Additional resources like online courses, mock interviews, and networking events can help you prepare better for your interview. Good luck with your next interview!
