How to prep yourself for a software engineering interview?
Here’s a list of prerequisites you should take care of before appearing for a technical interview:
A good resume is the first impression.
Your resume as a software developer is considered the first stepping stone towards landing a call for an interview. This is your first impression and should be powerful enough to last as well.
Preparation for a software engineering interview comes after you get shortlisted for one.
A good professional resume for a software developer should be well-structured, highlight results, and optimized for the right technical keywords according to your job, so that it can be passed as an ATS-friendly resume.

Know your Target company well
This is a crucial step before starting your preparation for a software engineering interview. Conduct thorough research on your target company and understand their mission, values, their in-house culture, the projects they have worked on earlier, and the technologies they use.
After that, focus on the job description and highlight the points that discuss your roles, major responsibilities, and Teck-stack required for the position.
Conducting research in this way will help you gather the basic knowledge needed to land that software engineer job in the target company.
This will prepare you for the interview questions according to the expectations of the employer, eventually helping you stand out among the fellow interviewees.
Choose a programming language of your choice
Since you’ve already researched the technologies used by the company, in this step, you should pick a programming language to use in your coding test.
When it comes to choosing a programming language, it shouldn’t be about being efficient in most of them rather being good and comfortable with one.
You can pick any among JavaScript, C++, Python, or others and use it for the preparation for software engineering interview questions effectively.
Effective use of a single programming language will also help you demonstrate your technical skills as a software developer, along with skills like problem-solving.
Conduct an informational interview
This is an excellent yet the most underrated step while preparing for a software engineering interview. This is an informal method to get yourself prepared for a job interview according to the employer’s expectations.
You can conduct an informational review by reaching out to experts in your field or, specifically, the current employees of the company, to get significant details regarding the role and company culture.

What questions are asked in a software engineering interview?
Looking for the right questions for a technical interview preparation?
Interview questions are designed according to the role you’re supposed to get interviewed for, but here’s a list of software engineering sections that are mostly used in interview questions for entry-level to senior developers’ interviews.
Section of a software engineering interview
- The Coding Test: These tests are almost a part of every interview conducted for a software engineering role to assess the knowledge of the candidate regarding data structures and algorithms.
During these tests, you will be given questions regarding graphs, arrays, dynamic processing, and others to analyze your problem-solving skills, along with efficiency in writing clean code.
- System Design Test: This test is mostly given to candidates who are interested in mid to senior-level software engineering roles. When it comes to these roles, interviewers want to assess the capability of the candidate to build scalable and secure systems.
Preparation for a software engineering interview for a senior level should include practice of designing systems with reliability and data management in mind.
- Behavioral Test: These software engineering interview questions are based on the non-technical aspect of being a developer.
Employers use these questions to assess a candidate’s soft skills, including communication skills, teamwork, leadership, and others.
Types of Interviews
Preparation for software engineering interviews could become easier when you’re aware of the types of technical interviews conducted by organizations around the world.
However, it is not necessary that you’ve to go through all interview formats, since it depends on the company you’re going to work with.
- Quiz or screening tests: These are initial tests with basic software engineering interview questions, structured in a way to assess the core concepts of the candidates to filter out the best one.
- Coding tasks (online): These tasks include algorithm issues, and candidates are expected to solve them by writing code through platforms like LeetCode, HackerRank, and more.
- Online interviews: These types of interviews are mostly conducted through phone or video call between the interviewer and interviewee through platforms like Zoom, Teams, or Google Meet. Candidates are mostly asked to solve code-related questions through collaborative platforms such as Google Docs, Coder Pen, and more.
- In-house interviews: This is mostly the final stage of an interview process before getting your hands on an offer letter. These interviews are mostly longer than others and consist of different phases of tests, including coding problems, designing questions, and behavioral tests.
What are five tips for a successful software engineering interview?
Preparation for a software engineering interview is one thing, but nailing the interview can be hard if you miss these useful tips:
Be clear
To crack a software engineering interview, you’ve to be clear about the interview and test questions as much as possible. For example, developers jumping in directly to write the code without getting proper clarifications regarding input/output, data size, edge cases, and other things end up failing the tests as well as the interview.
Put a solution first
Most of the time, candidates are given complex questions to solve within a limited time. To tackle this issue, you should always strive to give a solution verbally before starting to code so that the interviewer is aware of your answer and thought process as a coder.
Write efficient code
One thing that you need to focus on during technical interview preparation is to write code with clarity. Once you appear for an interview, you’ll be required to write clean and effective code that is well-organized so that you can crack the interview.
Prepare according to the STAR method
Suppose you ace the technical part of the interview but fail badly while answering the behavioral questions. You need to practice using the STAR method when preparing for a software engineering interview.
The STAR method is an abbreviation for Situation, Task, Action, and Result. This helps you structure your answers properly during behavioral tests and demonstrate your mindset, communication skills, and more.
State your past experiences
During your interview, you will be asked in detail about all your previous work experience, your main responsibilities, and the results that you achieved. It is better to highlight those experiences that used transferable skills that are required by the target company, for the role you’re seeking.
What is the STAR method?
As we’ve discussed earlier, the star method is an interview technique that is used to answer behavioral questions in an effective manner.
Preparation for software engineering interview’s behavioral questions becomes quite easy if you understand this method and try to implement it while describing your previous experiences.
Let’s break down the acronym STAR to understand the method in detail:
- Situation: Start by explaining the context of your experience accurately.
- Task: Then explain your main role in the situation as well as the goal you wanted to achieve.
- Action: In this step, shed light in detail on the steps you took to achieve that goal.
- Result: Lastly, share the output of the actions you took to complete the task. Explain the level of your success along with the learning experience you got while doing that task.
Using this method to answer the questions will increase your chances of clearing the interview.
How many rounds of an interview are normal for a software engineer?
The process of a technical interview consists of several rounds, timed for 45 minutes to an hour. During these rounds, candidates are assessed on different technical as well as non-technical bases.
In-house interviews typically consist of three or more rounds where candidates are expected to complete coding, designing, or other tests.
